HI 83141

Portable Analog pH/ORP Meter

HI 83141 is a handheld pH/mV/°C meter designed to be reliable and easy-to-use.

HI 83141 uses the HI 1230B pH electrode and HI 7669AW temperature probe using separate connections (both included).

Manual calibration is performed at one or two points by adjusting the knobs on the front panel. This instrument is ideal for applications that require a custom calibration point. Manual calibration can be extremely useful in order to achieve better accuracy.
