This document is the user manual for Hanna's thermometer.
This document is the instruction manual for the Hanna Instruments HI 146-00 and HI 146-01 thermometers. These instruments are designed for simple continuous monitoring of temperature with a sealed housing and an easy-to-clean stainless steel probe.
The manual provides operational instructions, including how to dip the probe, avoid damaging the cable, and interpreting display readings. It also details procedures for performing a calibration check using an internal switch and replacing the AA alkaline battery when the display fades.
