Description
Overview
This upgraded version of GAOTek’s ion meter supports a large range of ion modes such as H+, Ag+, Na+, K+, NH4+, Cl-, F-, NO3-, BF4-, CN-, Cu2+, Pb2+, and Ca2+. It allows users to measure pH/pX, ion concentration, and potential temperature. Moreover, the device provides several ion concentration measurements, including direct reading of concentration, standard addition mode, sample addition mode, and GRAN mode. With three measurement modes, including continuous mode, timed reading mode, and auto-lock reading mode, this ion meter can recognise several pH buffers which meet with the GB, NIST, and DIN standards and can calibrate up to 5 points. The device adopts dot-matrix LCD screen with light touch keys that offers power-failure protection functions as well as automatic temperature compensation functions. By having a USB interface, this ion meter allows users to delete, view, print, and exchange data with computers.
