Best Handheld TDS/EC/TEMP
Posted: 12/12/2015 from Long Island, NY UNITED STATES
I've had a few different HM Digital handheld TDS checkers over the years. This is by FAR the best one. Not only does it check for Electrical Current (EC), it has a Fahrenheit Thermometer and has digital calibration, so no more turning screws with a micro-screwdriver to calibrate, as well as ppm & ppt in multiple formats (NaCl, 4-4-2, ect...). Another great aspect is that it's WATERPROOF and floats! You don't know how many of these I've accidentally dropped into the tank, sump or RODI reservoir. HM Digital also makes most of the inline TDS monitors for RODI systems. I would stay away from Hanna, but HM Digital is solid, in my opinion. Whichever device you go with, make sure you pick up the HM 342 NaCl Calibration Fluid for it. Good Luck with your tanks & Happy Holidays (written in December)
