Bluelab Truncheon Meter

The world's favorite nutrient meter! With its super tough, high quality, fully waterproof design, no calibration required, daylight readable blue LED's and no on/off buttons to worry about, the Bluelab Truncheon Nutrient Meter has proven itself as the world's favorite nutrient meter.

There is no easier conductivity meter to use than the Bluelab Truncheon Meter! OK...how simple is it to use? To find the conductivity of your solution, simply place the probe head into the solution for 1-2 minutes (automatically turns on) to reach the same temperature of your nutrient. Remove from the solution (automatically turns off) and place back in. The bright, easy to read Blue LED's will flash next to a number/s on the scale of your choosing. Rinse the probe after use in fresh water to stop nutrient salts building up on the probe face and clean once a week to ensure the Truncheon Nutrient Meter remains accurate. It is fully waterproof so if you drop it in the tank or into the swimming pool, it's OK!

Calibration of the Meter is not required and it's great for stirring your nutrient tank too!

The Truncheon Meter measures the amount of dissolved solids in a solution and gives you a conductivity reading. To maintain optimum plant growth and phenomenal crops, you need to KNOW what the conductivity of the solution is before feeding your plants AND while they are growing. If the solution is too weak, your plants will miss out on the vital elements they need to grow. Too strong and you risk root burn, especially if evaporation occurs within your growing environment. The nutrient solution needs to be measured regularly so you know when to add more concentrated solution or when to add fresh water. Without a Truncheon Meter to measure it, you are only guessing and risk crop failure.

Conductivity is the total soluble salts contained within a liquid solution. Because pure water does not conduct electricity it has a conductivity measurement of zero. By adding soluble elements to the water, electricity is able to move through the solution giving it a conductivity rating. Conductivity is measured using various scales. The scales the Truncheon will provide you is EC (Electrical Conductivity), CF (Conductivity Factor), ppm 500 (parts per million) which is also known as TDS (Total Dissolved Solids) and ppm 700.

EC and CF are the only two absolute scales of conductivity, however the USA mainly uses the ppm 500 scale (also known as TDS). The UK mainly uses the ppm 700 scale. Conductivity range for the Truncheon is; EC (0.2 - 3.6), CF (2 - 36), ppm 500 (100 - 1800), ppm 700 (140 - 2520)

Nearly all conductivity meters need to be calibrated. The great thing is, the Bluelab Truncheon Meter does not need to be calibrated as this is locked in during manufacture. The only maintenance it requires is cleaning the probe and changing the batteries. 'The instrument is only as accurate as the probe is clean' - easy probe cleaning and a quick test is all you need to do to keep the Truncheon Meter operating perfectly for years!

The Truncheon is 400mm/16" long and 24mm/1" wide. It weights only 225grams
