Long-life pump heads are easily replaced in seconds without tools.



This is probably a little bit tight so Im going to change this to 1.0 so if it goes below 4.9 or above 6.9 it will set off an alarm. It takes relatively small amounts of pH adjuster to make big swings in pH. Controller, dosing pumps and water manifold are all conveniently mounted on a stainless steel back panel simplifying installation and providing a clean appearance.

The Quick Connect DIN connector creates a waterproof seal with the meter making it ideal for reducing electrical noise issues with the connection caused by humid environments. |

MDXP Modular Dosing Panels automate nutrient dosing, pH and ORP control in large or small re-circulating hydroponic systems or drain-to-waste fertigation systems fed from a pre-mix stock tank.



If you have a commercial enterprise then this is a must, you wouldnt want to lose an entire crop due to a bad pH probe adding a ton of acid/base to your solution. The controller then shuts off the pump.

There are a few settings here.

If you can then I would advice you build your own controllers using things like arduinos, raspberry pi computers and robust immersion pH probes so that you can have an optimum setup that can deliver all the advantages of pH control with as few disadvantages as possible.

A representative will contact you within the next 2 hours.

All rights reserved. If you use too strong of an acid solution the controller may not shut off the pump in time and the pH will drop well past the pre-set limit.

When using a pH controller you should place the pH probe as far away as possible from the place where your pH up/down solutions will enter the hydroponic system. I like to make a Styrofoam float for the probe to keep it from sitting on the bottom.

These units are very accurate and only need to be calibrated every two weeks. The HI981412 uses the HI10063 amplified probe that incorporates both pH and temperature sensors and connects to the controller with a single waterproof Quick Connect DIN connector. If an electrode is covered in biofilm the putting it in a hot bleach solution for half an hour before the buffer immersion is also necessary.



Dont use very concentrated acid/base input solutions. So right now its saying that if it goes point five outside of your set point that the alarm will go off. Tmall Taobao World The peristaltic dosing pump can be controlled by simple on/off or more advanced proportional control which helps prevents overshooting of the set point. For example a controller can be told to maintain pH in the 5.6-6.4 region and then it will act whenever the pH reaches 5.6 or 6.4 to take it back to 6 when any one of these two thresholds is breached.

Regular pH electrodes including those sold with some automated pH controllers are not meant to be immersed the whole time and therefore get damaged and lose calibration much more quickly when used in this manner.

Thank you for your interest in our products.

The pump delivers acid solution to the reservoir until the pH drops to your selected set point. pH fluctuations in your reservoir are not only time consuming to correct but can have negative effects on your crop performance. 33010002000092

Dont place your pH probes near pumps or other electrical equipment in reservoirs. Although most growers control pH manually it is often desirable to implement automatic pH control so that you can ensure that your solution always stays within an optimum range. Thanks for signing up.

Growers everywhere have stopped the daily battle with pH levels, giving them more time to spend on their plants. Allowing a pH controller to add as much substance as needed to correct the pH can be a very bad thing to do. Usually they wont do that that often but that would give you a heads up that maybe something is wrong with either your solution or the probe if it is dosing more often than that. When the pH raised above the set point than you have selected the Controller turns on a small pump that is placed inside a bucket with a diluted acid mixture (water and Phosphoric Acid usually).

Hold edit and you can move it up to exactly 7.0 and get it set in and then once youve calibrated to the 7 you calibrate to the 4 and you hit menu and you can go to your basic readings.

Terms & Conditions, Agrowtek Inc. Available in 1, 2, 4, 5 or 6 pump configurations.

You should use a diluted acid solution.



Therefore its always best to use two-probe controllers where readings are always verified across the two probes to ensure that the reading the controller is getting is accurate. You select a slightly lower set point for the back-up controller. Dont ignore your controllers data.

The pH controller monitors the pH of the system.



Precision sensors and rugged pumps offer reliable and accurate control.

Maintaining the correct pH of plant soil or hydroponic nutrient solution is an ongoing task.

HI10063 amplified pH/Temperature probe with quick connect DIN connector - galvanically isolated. You then have your alarm dose count per hour so currently it set at if it dosing more than 10 times in one hour it will set off an alarm. Its a really simple doser unit and it just adds pH adjustor to your reservoir, as needed, to maintain your pH levels.

This unit comes with a peristaltic pump, allowing you to keep your pH adjuster in larger containers on the floor, avoiding issues associated with gravity-fed valves. Usually the best way for a controller to act is to have a range with high/low thresholds where the controller will act to take the pH to the middle of the range when these thresholds are exceeded. Simply insert the probe and injection valve in-line with the recirculation pump and provide the chemical to be dosed. Hi, Im Kelly with American Hydroponics and I want to talk to you about our pH Mini Doser.

- Manuals & Videos Add a peristaltic pump to create a fully functional dosing system.

It makes for a more accurate reading.

How often your pH controller has to add acid/base and how much acid/base its using to perform its job are important pieces of information that you need to take into account in order to ensure that your system is working properly.

The store will not work correctly in the case when cookies are disabled. A pH probe can get damaged, it can lose calibration or it can give erratic readings due to other reasons (for example electrical interference from other things in the reservoir).

It saves you a lot of time and energy and makes your plants really happy.

Recirculating Hydroponics Systems (NFT, DWC, etc.

The pH Mini can dose pH either up or down, depending on your systems needs.



Placing the probe close to the inputs will cause very erratic changes in the pH that do not really reflect the effect of the addition across the entire reservoir. Right now we have it set to off but if you want it to audibly make noise in your grow room you can just change it on.

However if the pH is at 6.4 and the controller drops it to 5.8 it will not try to then bring the pH up (because its above the lower threshold).

From all of us here at American Hydroponics, happy growing.

Remember that pH controlling substances often also contribute nutrients like phosphorous or potassium so its important to keep all these additions in check.

Do place your electrode as far as possible from your pH changing inputs. If I wanted to change my set point, right now were reading 5.9 pH, I go to menu, settings, go down and it says S1, so thats S1 and thats my set point and if I hit edit I can change that lets say to 6.0. The controller will add either acid or alkali (to lower or raise the pH). Always have controllers where maximum additions per unit of time can be specified so that the possibility of this happening is minimized. pH control by the experts! So its very simple to set. -

Of course pH control is no simple task and different pH controllers will have different advantages and disadvantages. This input can be used to disable the dosing pump when there is no chemical left in the reservoir tank or there is no flow due to the pump being turned off.

If I go down to S3 which is my dosing interval, thats how long it waits between doses and I have it set at 20 minutes if I wanted to change this lets say 15 minutes because its a pretty small reservoir, I hit edit, get to 15, release and thats set.

This means that testing your pH meter with a buffer solution often every week is ideal is necessary in order to ensure that you are getting accurate readings.

A pH controller should not aim for a specific value of pH but to maintain pH within an adequate range. I usually take the stock liquid pH adjuster available from most Hydro shops and dilute it to 1 part pH adjuster to 8 parts water.



This simple pH Mini will monitor your pH levels and add pH adjuster to maintain your desired set-points. You should have very good circulation in the reservoir so the acid will mix quickly with the nutrient solution. In hydroponics pH meters can lose calibration rather quickly as a consequence of being immersed in a nutrient solution that is at a lower ionic concentration than whats ideal for most glass electrodes. The system is designed to lower pH only.



Macro and micro nutrients, as well as calcium and magnesium bloom boosters, require the correct pH for absorption into the plants root system.
