Have had cheaper pens that have not lasted even with careful use. This pen has lasted through two seasons of almost daily use. Very accurate - hits test solutions perfectly. The extra money spent is worth it unless you like replacing pens every year.

Works great. I’m just now learning how to use it in my hydroponics greenhouse but seems to be accurate.

Great products that ar reasonably priced!every Blue lab product I have bought performs excellent.This EC meter is easy to use & Read.It feels like it is well built.you can get a $ 20 meter somewhere else but you will have replace every year or 2 .When dealing with something as important as EC & PPM for your plants or whatever,get the trusted name proven from years of well built products, Blue Lab.

I started with ordering the grower's toolbox at the very end of January -- it was delivered February 1st and the EC pen was dead before June 1st. I figured that it wasn't too serious, since sometimes these things happen and it should have a warranty. In the meantime, I decided I'd order a new EC pen since I have to make sure to feed my plants properly -- they're very picky. The new pen arrived within days and after thoroughly cleaning and rinsing, as instructed to before calibration, I attempted to calibrate the new EC pen. No dice. Tried cleaning and rinsing again -- nothing. I contacted Amazon and got a replacement sent (props to Dash for getting me taken care of quickly and painlessly), and tried to clean and calibrate the NEW EC pen...to absolutely no avail. Still getting "Er" code on the display.So it seems that no matter what I do, Bluelab products are simply not worth the effort to try and use and DEFINITELY not worth the cost. It's a shame, really, because I feel like I remember their products actually working when I first started using them 3 years ago or so. I will be looking for a new manufacturer for my plant feed analysis products and highly recommend that anyone reading this review does the same!UPDATE: After having reached out to Bluelab and left a message, I received a call back from a representative that asked for some details related to the products. She guessed that the EC control I was using was expired and sent me new EC solution, as well as pH probe storage solution and pH 4.0 and pH 7.0 controls. After cleaning the probes again and using the new solutions sent to me, both pens (pH and EC) were able to be calibrated. I was told that if, for whatever reason, the new solutions didn't work to contact Bluelab again so that they could rectify the situation. All in all, I'd buy this product again, but probably directly from Bluelab since they pointed out that solutions in/with products sold by other parties may be past their prime.

This company is great and has long lasting and accurate products. I use all their devices as I deal with a cash crop. I have tried other brands early on only to find them to be inaccurate and a short life.I have dealt with their customer service and they stayed in touch until a service check was done on one of my pens. It ended up that the pen was not faulty and the promptly returned my pen working flawlessly. I have come to trust bluelab’s product line and will not be changing where I choose to spend my money.I recommend this to any new grower to prevent failures in the field.

A necessary tool for beginners in hydroponics. I’ve been using it to maintain the desired nutrient levels in my first dwc for the past 3 months with no complaints. It would have been nice if it came with a pouch to store it in but that’s not a big enough con for me to deduct a star from it.

Highly recommend this accurate and built to last EC/TDS meter. I use this meter daily for monitoring the TDS of hydroponic system and this meter is by far the best. I’ve had numerous other cheap and one 3 in 1 meter in the past and they all stopped working accurately after only a couple of months of use to the point the weren’t able to be recalibrated. The BlueLab EC/TDS meter works without fail every time and it has a replaceable battery!!

Bluelab seems to make good quality products. My EC pen has worked well for over a year now. It has remained accurate.

Das Produkt funktioniert einwandfrei. Mir hat es die umweltfreundliche Verpackung besonders angetan, kein unnötiges Material verwendet. Alle Infos inklusive Anleitung wurden innen und außen auf die Packung gedruckt. Stark!
