The HH370 is a waterproof, highly accurate handheld RTD temperature meter that uses the dedicated probes RTD-370-PT100 and RTD-370-PT1K. These probes have a water-resistant connection and a measurement range of -100 to 300°C (-148 to 572°F). The 100 Ω probe is included with the unit.

Stable, accurate and surprise extraThis unit has excellent accuracy specs and works perfect for the narrow temperature range I need it for. Not mentioned on the website description was a built in function to memorize a reference temp and monitor the change in temperature. This is perfect for my application and I’m very pleased with the unit.

The HH370 is just what I neededI bought this temperature meter about a month ago. I needed to insure that a low cost digital thermometer was measuring correctly. The HH370 allowed me to quickly and easily confirm the temperature measurements. I plan to use the HH370 as a temperature standard which will allow me to adjust other low cost temperature controllers and meters to insure that they are measuring accurately.
I did purchase the small carrying bag along with the meter. I was disappointed with the bag due to the fact that the probe will not fit in the bag. The probe is too long. This tends to render the bag useless since I prefer to keep the meter and the probe together as one unit.
