Manual calibration is performed at one or two points by adjusting the trimmers on the front panel. Capable of measuring pH/mV and °C, this meter are great for field work, providing one meter for multiple uses. This instrument is ideal for applications that require a custom calibration point. Manual calibration can be extremely useful in order to achieve better accuracy.
This meter can also be used for ORP measurements with the optional probes below: HI3131B
