HI 23151-02 Conductivity meter with automatic temperature compensation, analog and analog output

HI 23151 conductivity is a professional bench multiscale, combining precision, ease of use and convenience. And ‘ideal for any application laboratory, especially for teaching. The 4 scales covering every possible application, from deionized water to brine. Calibration manual, 1 point is accomplished by simply turning the knob on the front panel of the instrument.
All measurements in each scale are performed with a single 4-ring potentiometric probe with platinum. This type of probe technologically advanced it is easier to clean and resistant to corrosion and temperature compared to a conventional amperometric. In addition to the change does not require recalibration of the measuring scale.
HI 23151, thanks to built-in temperature sensor in the probe, automatically compensates for measures with adjustable factor.
This tool comes with glass probe, platinum rings and protective sheath of plastic material, suitable for applications even in very acidic or alkaline, and in extreme temperature conditions. Thanks to the analog output is also possible to connect to the instrument recorder.
