The Truncheon Meter - information

It is essential when growing with a hydroponic solution to know what the strength of the solution is before feeding your plants and while they are growing. If the conductivity reading is too low, your plants may not be getting enough nutrients. If the conductivity reading is too high, plants can dehydrate.

 

How to take a reading:

To measure your solution, simply place the meter's probe head into the solution and the reading will be indicated by flashing lights on the meter. 

If the flashing lights are alternating between two numbers, the reading is the value between those two numbers. For example, if the lights are alternating from 0.8EC and 1.0EC, the reading is 0.9EC.

To take another reading, simply submerge your meter probe head into the solution again. 

Calibration of the Truncheon® Nutrient Meter is not required, these meters are factory calibrated. The probe just needs to be kept clean.

The Truncheon Meter has four available scales: EC, CF, ppm500 (TDS) and ppm700 (EC x 700). 

 

How to clean your probe:

 

How to replace the batteries: 

These meters use 3x AA batteries - always ensure alkaline batteries are used.

Never use rechargeable batteries.

Unfasten battery cap and tip out old batteries.

Insert new batteries with positive (+) end down. Screw the battery cap back onto Truncheon securely, leaving not gaps between body and cap to ensure unit remains 100% waterproof.

Quick tip:
    Besides being used to measure nutrient levels, the Truncheon Meter can also be used to mix your nutrients into your solution.
