  • Both items measure conductivity across all scales: EC, ppm 500, ppm 700 & CF. The original Truncheon (the page you are on) measures in tighter increments, while the Commercial Truncheon (the other option) measures a wider range, up to 6.0 EC.

  • The Bluelab Truncheon is designed for growers who use batch tanks and/or who hand-mix their nutrients. It's rugged design allows you to use it as a stir stick while you mix your solution, getting instantaneous conductivity readings at the same time.

  • We did! This is an original proprietary design by Bluelab, built on our over 30 years of growing & hydroponics experience. Each Truncheon is built, calibrated and tested by our trained technicians in New Zealand. Please beware of imitations.

  • The Bluelab Truncheon has been built tough to withstand the day to day rigors of growing and is virtually indestructible. It is fully waterproof, does not need to be calibrated, and only needs a simple rinse after each use.

  • The Bluelab truncheon was designed to work effortlessly right out of the box. It auto detects when placed in liquid, with bright LED lights showing the measurement. No calibration is required, and the Truncheon is super easy to clean & disinfect.

The meter feels solid and well constructed. The plastic is thick and study (no creaking or flimsiness). The battery compartment has a proper O-ring and the rest of the unit looks to be sealed with glue/silicone. Nice Japanese OEM batteries are included so it's ready to go out of the box.It's a bit larger than other meters, but that makes it easier to handle. The lanyard very convenient when taking direct measurements inside larger reservoirs such as 50 gallon drums. Even if you do drop this meter into your reservoir it'll be fine because it's fully waterproof.This meter does not provide exact numeric measurements on a display like some others, but the LED indicators are easy to read and intuitive. If one indicator blinks, then your nutrient concentration is at that level. If two LEDs alternate blinking then the measurement is about halfway between those values. The precision should be enough for any hydroponics system.The meter turns on automatically when it detects water above the minimum PPM and turns off automatically after displaying the reading for a while. There are no controls on the meter. It doesn't turn on when immersed in common tap water, so accidental battery drain isn't a problem. The detector element itself is also very sturdy and easy to clean. I usually rinse it off every few measurements and store it in the protective case.Buy it!

Bluelabs make the best devices for ph, ec and temp in the Hydroponic community ! They last a long time and they have grate customer services it you have a problem, you can all them and they will help you get your problem fixed. I bought this EC tool so that I could muser the amount of nutrient that I had in my nutrient tank to make sure that the levers are the right amount. I grow many different kind of vegetable and I use different kind and mik different types of NPK for all they different system that i have so I use this tool to make sure that each nutrient tank has the right amount of nutrient in it. I love this tool . It is worth paying for the real name brand tool !

This product is a joy to use! Upgrading from a cheap Chinese-made digital meter, the experience is night and day different. The readings are quick, CONSISTENT, and super easy to read. I love that this doubles as a nutrient stir stick, and the no button/no switch design makes it effortless to use.Here's the difference between this product (commercial) and the standard truncheon: the commercial has a wider measurement range, from 0.4 EC to 6.0 EC. That's it. The standard truncheon goes from 0.2 EC to 3.6 EC. The standard model is fine for any hobbyist, but you may want the commercial if you are going to mix up nutrient liquid concentrates, and then add them to your nutrient reservoir through an automated measuring and dosing system.I purchased the commercial model because it was on sale for the same price as the standard model, and I thought "commercial" must equal "better." I probably don't need the increased range, but I have no regrets: it works perfectly fine for my purposes, and I can upgrade later to an automated dosing system if I choose.Whichever model you get, the Truncheon is absolutely worth the price of entry. It's so easy and intuitive, and cleanup is just a spritz of tap water or a dab with a towel. Nutrient testing is now my favorite part of the routine.

I absolutely love it. It is so simple and the idea behind being able to stir and drop it is definitely what got me to buy it i highly recommend
