Supported Applications
The Omega HH370-Series is a digital RTD thermometer designed for industrial temperature measurement applications. It operates with platinum-type Resistance Temperature Detector (RTD) sensors, specifically Pt-100 and Pt-1000 elements.
Operating Conditions & Performance
The series measures temperatures across two defined ranges: -100°C ~ 300°C (-148°F ~ 572°F). Accuracy is specified as ±(0.1% reading + 0.4°C) for the Celsius range and ±(0.1% reading + 0.8°F) for the Fahrenheit range; this specification excludes probe error, which must be referenced separately from the probe accuracy data sheet.
The device features a resolution of 0.1°C or 0.1°F on its 4-digit LCD display. It is rated IP67 for enclosure protection and operates within an ambient temperature range of 0°C ~ 50°C (32°F ~ 122°F) at humidity levels between 0 ~ 80% RH. Storage conditions are defined as -10°C to 60°C (14°F ~ 140°F).
Configuration Options
The HH370-Series is powered by three size AAA batteries at 1.5V each. The unit measures approximately 150 x 66 x 31mm and weighs about 175g.
- Sensor Compatibility: Designed for Pt-100 (Class A) and Pt-1000 probes.
- Housing & Protection: IP67 waterproof rating suitable for industrial environments.
- Power Source: Battery operated (3 x 1.5V AAA).
- Accessories: Connection cables are available as optional accessories alongside the Pt-100 probe and instruction menu.
Key Product Differences
The series is identified by the model code HH370. The product overview notes that these devices carry CE, ISO 9001, and ISO 9002 certifications. A specific warning states that these products are not designed for use in human applications.

Stable, accurate and surprise extra
This 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 needed
I 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.

Can I order the HH370 RTD Thermometer with its probe calibrated at two points 0 & 100 C with NIST cert included ?
Calibrating at customer specific temperatures needs to be priced by the Temperature Engineering group. You can send your request to temp@omega.com and someone will assist you.

Can RTD Pt100 &amp handheld measure when extend the Rtd PT100 with cable to 100m far away? Is it suitable with an explosion proof ExiaI?
The meter and probe are an integral system for this meter and there are no extension cables offered. In general it would not be recommended to run long lengths of RTD cable as the wire would add additional Resistance affecting the accuracy of the measurement.
