Model WL-15A Ion Meter ------serial products of ion meter Model WL-15A Ion Meter is a great tool for any laboratory operator and field user, which is one of the most accurate ion concentration (pX) testers available in the market. It has the functions of automatic temperature compensation and self-diagnosis. Equipped with different ion selective electrode, it can measure different ion concentration value of different sample solutions and the potential (mV) of electrodes. Furthermore, it also can be used as a terminus display device for potential titration analysis. Its high accuracy and resolution make it suitable even for all the most-demanding solution pX/mV measurement, such as chemical solutions, waste water or any other water based liquid. Specifications: Measuring range: pX: 0.001 10.000pX mV: -1999 +1999mV Temp: 0 60 oC Accuracy: pX: 0.005pX mV: 0.03% FS Temp: 1 oC Resolution: pH: 0.001pH mV: 0.1mV Temp: 0.1 oC Temperature compensation range: 0 oC 55 oC Input resistance: ≥3×1012Ω Power source: AC 220V ± 20V 50Hz ± 0.5Hz Dimension: 300mm×280mm×180mm Power consumption: 25W Weight: 3kg Characteristics: Automatic temperature compensation Two- point or three- point calibration High accuracy and resolution Reliable and stable Easy-to-operate
