EC METER HANNA DIST 4

Regardless of what field you are in, the amount of salt or solids (TDS) in water is important. The DiST testers are reliable, pocket-sized instruments that will give you quick and accurate readings of conductivity and TDS.
The casing of the popular DiST testers has been redesigned for increased strength, to better fit your hand and also offer a much larger LCD for easier viewing.
The graphite sensors provide better repeatability since they do not oxidize.
The probe is user replaceable. In fact, the whole PCB module slides out and can be replaced.
The casing has been shaped in such a way as to ease air bubbles out.
The temperature sensor is exposed and provides faster response time. Temperature effects your conductivity measurements by 2% per degree centigrade.
Automatic Temperature Compensation assures that all readings are corrected to compensate for the effect of temperature. An LCD displays the digits clearly so they can be read at virtually any angle. If calibration is necessary simply submerge the electrode into calibration solution, and turn the trimmer at the back of the tester.
