    This controller is great – I’ve purchase 4x so far. Previously used Cole Parmer controllers, but when I got a bad batch I found Sensorex’s and have decided to transition over entirely. The sensor they use for connecting to pH probes is great – I haven’t had problems with ANYTHING I’ve plugged into it. Wiring is very easy, even interns could figure it out with little instruction. It’s at least $100 cheaper than the next option – give it a shot!
