Conductivity & TDS Meters with ATC, Digital - DiST 1 TDS Tester - HI98301

The DiST testers are reliable, pocket-sized instruments that will give you quick and accurate readings of conductivity and TDS. DiST 1 and DiST 2 measure TDS, while DiST 3 and DiST 4 measure conductivity. The probe is user replaceable. In fact, the whole PCB module slides out and can be replaced. The temperature sensor is exposed and provides faster response time. If calibration is necessary simply submerge the electrode into calibration solution, and turn the trimmer at the back of the tester.
