Calibration Solutions

Calibrating liquids for pH and Ec meters

Calibration Solutions are the only way to get reliable results from your pH and EC meters; these devices need to work as precisely as possible. Each solution is a specific pH or EC level, which allows you to calibrate your meter to the same level and keep it working like brand new.

You can choose between pH 7 and pH 4 buffers, which allow you to calibrate any pH meter on the market. Some of them simply require a button to be pressed, whereas most meters require you to adjust a screw that controls the calibration. The meters that require the screw to be turned usually only need one calibration sachet, whereas the other ones may require two, one of each.

We also stock EC liquids, 1413 and 12880 to be specific. Some meters require one type, and others require the other type. The 1413 buffer is usually required for meters that don’t go over 9.9, and the other one is for meters that go over 9.9 (even if your plants won’t even come close to this much EC) – very few meters require this specific liquid, such as the waterproof ADWA meter.

In order to keep your meters clean of minerals you’ll need to use a cleaning solution made specifically for this purpose. Simply place the sensor in the cleaning solution and it’ll rid it of any accumulated minerals, which can affect readings; keep your devices working as precise as possible.

You’ll need to do some regular maintenance when it comes to keeping your pH and EC meters working properly. It’s not good for the sensors to be dry for too long, especially not the pH sensor. When you put it away you’ll need to place the sensor in some liquid. This stops it from drying out too much, which can cause it to flake and break. Use our maintenance liquid in order to keep your sensors hydrated and working like brand new – if you use normal water and then let it dry out, it may end up covered in lime which could also break.

We stock 20ml sachets as well as 250ml bottles; depending on how often you plan on using your meters, you’ll need more or less – the sachets are one-use only, whereas the bottles save money and time; cleaning and maintenance liquids only come in 250ml bottle.
