Supported Applications

The Omega HH376-Series is a digital RTD thermometer data logger designed for use with platinum-type temperature sensors. It features a 5-digit LCD display and supports both Celsius and Fahrenheit scales, enabling users to log temperature data at configurable intervals.

  • Data hold function
  • Relative mode operation
  • Max/min tracking
  • PC communication via USB interface

Operating Conditions & Performance

The HH376-Series measures temperature across the following ranges with specified accuracy:

  • -100°C ~ 400°C: ±(0.05% reading + 0.1°C)
  • -148°F ~ 752°F: ±(0.05% reading + 0.2°F)

Resolution is provided at 0.01°C and 0.02°F. The device operates within an ambient temperature range of 0°C ~ 50°C (32°F ~ 122°F) and a humidity rating of 0 ~ 80% RH. Storage conditions are specified as -10°C to 60°C (14°F ~ 140°F). The basic accuracy specification does not include the error of the probe; users must refer to the specific probe accuracy for additional details.

Rated 5 out of 5 by from Irreplaceable Tool Needed The Omega RTD Handheld Data Logger Thermometer allows us to retrieve the data we need to fine tune our testing systems. We use it here at an engineering firm where we design and manufacture advanced testing systems for material characterization. We consider the RTD Thermometer an irreplaceable tool we need to do our job.

Rated 5 out of 5 by from High accuracy and inexpensive Great little handheld with 2 digits of precision after the decimal. Data logging for charting responses, easy connect to computer for download of data. We use it to monitor differential temps near 100C and it’s very repeatable. Also nice is the 120V adapter so no worry about battery life. Highly recommend.

What would be the combined tolerance in °C @ 400°C? I'm getting conflicting answers with the probe being an A Grade.

Asked by: Earl
The total accuracy is the sum total of meter ±(0.05% reading + 0.1°C) and probe ±(0.15 + 0.002 · l t l )°C At 400 C the tolerance is +/- 1.05 C

I just got a brand new HH376 today, and noticed that when powering up, the display shows a number...."15959" and then the number disappears. I could not find any reference to this in the user manual and cant understand why this number shows up.

Asked by: Bob8900
Thank you for your inquiry. That number represents the number data logging points remaining in the unit.

Can you explain the accuracy spec? It reads 23+/-5°C, with no spec, then a range spec for -100 to +400°C.

Asked by: RPMS
The 23 +/-5 C is the ambient temperature the meter needs to be in to meet the accuracy specification over the measurement range.

NIST traceable option?

Asked by: Bumbleguy
Thank you for your inquiry. Unit is supplied with a NIST certificate (No Points). For an additional cost you can order with a NIST certificate with points.

Good day please, Does this thermometer include the temperature sensor or must be purchased separately

Asked by: Andres Cardona
The HH376 comes with it's own RTD probe with a special connector so it is included.

For the RTD HH376 unit, what temperatures are included in the optional 3 point NIST traceable certificate?

Asked by: Claybert
The NIST Certification included is a No Point document but usually the unit is checked at the low and high extremes and a value around room temperature.
