Meters


Bluelab Truncheon Nutrient Meter Bluelab Truncheon Nutrient Meter
The Bluelab Truncheon Nutrient Meter measures the nutrient strength of a solution. It is essential when growing hydroponics to KNOW what the strength of the solution is before feeding your plants AND while they are growing.
To take a reading of your solution - simply place the probe head into the solution for 1-2 minutes to reach the same temperature of your nutrient. Remove from the solution and place back in to take the reading as indicated by the flashing lights. Rinse the probe after use in fresh water and clean once a week to ensure the Truncheon Nutrient Meter remains accurate. It's great for stirring your nutrient tank too!

Electrode Storage Solution
Electrode Storage Solution
Use to store your pH meter electrode between use. This solution is designed to keep your electrode sensing membrane and reference junction clean and unclogged and ready for use. Store you electrode directly in a small cup of solution or saturate a sponge in the cap of your meter for storage between use. This will prevent your permeable glass membrane from becoming dry and from mineral deposits clogging the surface. This solution is designed to equalize the osmotic pressure of the reference solution in your meter junction to keep the reference solution from seeping out and prematurely aging your meter. Should your electrode membrane dry out soak it in this solution for at least two hours before use. NEVER STORE AN ELECTRODE IN DISTILLED OR DEIONIZED WATER.
