Recommend a good EC meter?

Blue lab EC pen. Comes with a year warrent, waterproof, and is top quality craftsmanship, not like those super cheap pens for under $20. But the cheap ones work fine too, I guess

I have a cheap £15 HM Digital off eBay and a BLT (Blue Lab Truncheon) both do same job, both match up. I calibrate the cheapo every 2 months or so in the recommended solution but never needed to do the BLT yet. You just put in solution and turn the little plastic screw until it reads 245 or whatever it is, reet simple imo. Truncheon is better as you can mix with it too 
OH IT ISN@T WATERPROOF!!!!

The combo meter is a Guardian that you can carry from res to res. I use mine a dozen times a day. I've broken one in four years of continuous use.
Bluelab EC meters DON'T NEED calibration.
PH tips eventually give up. Bluelab is very good about making sure their replacement tips don't sit on store shelves for too long and go bad.
Your water quality measuring equipment are your eyes and ears as to what's going on in your nutrient solution. You want 20/20... Or 'not exactly'? The potential value of the crop makes spending the coin for a top quality unit a no brainer.

Fuckin' Hanna, LOL an EC pen that ISN'T WATERPROOF?! WTF are they thinking?I have a cheap £15 HM Digital off eBay and a BLT (Blue Lab Truncheon) both do same job, both match up. I calibrate the cheapo every 2 months or so in the recommended solution but never needed to do the BLT yet.

Hanna has a factory here in in The Land Of Sticks, you can get one cheaper if I order
from the US and have it shipped back here.
Blue Lab will be my next EC meter, my Accent Meter is 13 years old and getting a
little worn out.

With bluelab stuff calibrating ppm just means cleaning the probe until it matches the calibrating solution ppm.

Yes I've cleaned it per instructions. It still reads 250 ppm off. I've cleaned 10 times. Same result.

I said anything about the Truncheon (I can even spell it). I am saying a decent meter does a great job for 90% of people smart enough to know how to use them. It is obviously a skill we don't all share. As evidenced by your post. Thanks for writing.

"The concentrations of KCl were confirmed using standard bench conductivity meter (HANNA Instruments, HI 8819, UK). The embryo chamber was filled with KCl solution (approximately 0.014 mL) using a pipette and covered with the cover plate. Both plates were then secured onto the holding electrodes of the impedance analyser."

Hanna Primos. Use the money you save for other supplies. But like I said to another poster the user MUST be smarter than the instrument they are holding. This goes for Blue Labs as well.

Why do things like this turn into a pissing match...the op asked for opinions on a good ec meter.Everyone is entitled to their own opinion.The op wanted some options now he has some good ones.
well worth the price. Still very accurate.

It's recommend you change it out every 6 months
I keep 3 together to make sure they are calibrated
