Bluelab Truncheon Nutrient Meter, Digital Conductivity Tester in Water (EC, 500, ppm 700, CF, TDS) Tool for Hydroponic System and Indoor Plant Grow

This item stopped working after 2 years. Has a 5 year warranty and I've contacted the seller with no response. If you buy it don't do it through AmazonUpdate: Beware of sellers on Amazon , they won't support you or the product they are selling. I am giving Blue Lab all the credit here. Their representative contacted me , got the info needed and refunded this purchase of the new one.Thank you Blue lab and I look forward to buying mor of your products .

Best one I ever used. I like not having to calibrate it ever. Exactly what I wanted a n d more.

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.

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 !

Works great easy to use, wait for a sale.

Great product package was negligent but it's a robust product

The media could not be loaded. We use it for measuring EC in the hydroponic nutrient solution on our market farm where we grow lettuce. It has been the best meter I've purchased so far due to not needing calibration and working as advertised right out of the box. Would buy again.

I bought a cheap brand from from Amazon and I was sorry. It took me a few days to realize what was going on, and by then, some of my plants were dead. The readings started being erratic, but unlike the airplane pilots that crash because they don't trust their instruments, I decided to trust my instruments, and that killed some of my plants. Then I bought this one from Bluelab. Problem solved. You get what you pay for and I know that, and I should have done this in the first place. It turns on when you put it in liquid and it turns off a few seconds after you take it out, to give you time to look at it even more if you want to before it turns off. It comes pre-calibrated and has a 5-year warranty. It's waterproof. It got here in about 8 hours with free shipping, and it came on Father's Day. Not that I want to but I can't figure out how anybody would rate this less than five stars.
