Bluelab Commercial Truncheon Digital Nutrient Meter

I seemed to have variations in my EC measurements in the beginning. I used a calibration fluid, which that or the Truncheon were suspect. . I contacted Bluelab twice, they answered promptly and they gave me some good advice. If you don't have the cleaning kit; which I don't, they advise plain old baking powder. Make a paste and give the electrodes a good cleaning . I used a piece of chamois on a plastic handle (non oily) They sold these to clean styus on analog record decks. I began to use the Truncheon with confidence. I have tested my tap water which comes out between EC .3 / .4 - Rain water doesn't conduct and shows nothing on the scale as it should. I am sure it is working fine now. The nutrient charts showing dilution and target EC values are in the 'ball park'. Initially one considers it expensive? however the guarantee period gives assurance and value. The Truncheon is very well made/manufactured so very durable and should last a long time. Conclussion: very good value and recommended

Alittle expensive but definitely works good,

So easy to use

Bluelab products are usually reliable and this one is too.

Best nutrient meter out there. Very tough it's always accurate and simple too use. Last for ages.

Best product out there for the price

Ordered and received a faulty product, amazon sent a replacement the next day. Spoke with Bluelab directly as well they were very helpful. 10/10 tool, somewhat analogue, no need to worry or guess anymore!

Quality product.

He usado varios y han durado lo que han durado con este llevo un año y van de lujo muy cómodo y práctico y muy fácil de usar y mantenerlo

Fungerar som den ska. Verkar vara bra kvalite.

Un po' grosso ma molto preciso ed efficace !

product arrived in perfect condition. works great for my soil cannabis grow !! I like that it has PPM & EC so I can track both easily without having to do the mental conversion. And I like that its a big ass wand. makes me feel magical around my plants. Expensive but if you are trying to grow well and know what your doing - spend the $$

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!
