Connect the correct thermal probe to your Field Gauge
Detachable thermal probes are not interchangeable with other Field Gauges. Each temperature probe is calibrated precisely to the Field Gauge it ships with at Ralston Instruments' ISO/IEC 17025:2017 Accredited lab.
To log temperature data to the highest possible accuracy, you must reconnect each thermal probe to the gauge it was lab-calibrated & certified with.
At the end of the job, it is common practice to disassemble equipment and pack it safely for storage and transport, including removing thermal probes from Field Gauges. Having multiple Field Gauges with temperature probes in your team's tool arsenal is also common. Because they all look identical, re-pairing probes with the correct gauges can quickly get confusing.
