Supported Applications
The Omega HH508 and HH509 series are compact, portable digital thermometers designed for temperature measurement using external Type K, J, T, E, or S thermocouples. These handheld meters provide a backlit LCD display with automatic polarity indication and overrange protection (-OL). The instruments follow Reference Temperature/Voltage Tables (N.I.S.T. Monograph 175 Revised to ITS-90) for temperature indication.
Key functional capabilities include:
- Data Hold, Max/Min recording, and Relative measurement modes
- Hi/Lo limit settings with an audible beeper warning
- Clock function and elapsed time tracking (HH509 series)
- Differential thermocouple input capability (T1-T2 on HH509 models only)
- Auto Power Off after 30 minutes of inactivity
Note: These products are not designed for use in, and should not be used for, patient-connected applications. Do not make temperature measurements inside microwave ovens.
Operating Conditions & Performance
The series supports a broad measurement envelope across multiple thermocouple types. The overall range spans from -210°C to 1767°C (-346°F to 1999°F), with specific limits per sensor type:
- K-TYPE: -200°C to 1372°C, -328°F to 1999°F
- J-TYPE: -210°C to 1200°C, -346°F to 1999°F
- T-TYPE: -200°C to 400°C, -328°F to 752°F
- E-TYPE: -220°C to 1000°C, -364°F to 1832°F
- S-TYPE: 0°C to 1767°C, 32°F to 1999°F
Resolution is selectable at 0.1° or 1°. Basic accuracy is stated as ±(0.1% rdg + 1°C) for K-type sensors in the -60°C to 1372°C range, with specific tolerances defined per type and temperature band (e.g., S-TYPE: ±(0.0% rdg + 2°C) on 0°C to 50°C). Accuracy specifications are stated at an ambient of 23°C±5°C <75% RH.
Environmental limits include:
- Ambient Operating Temperature: 0°C to 50°C (32°F to 122°F) with humidity <80% R.H. per manual, or stated at <75% RH for accuracy.
- Storage Temperature: -20°C to 60°C (-4°F to 140°F) with humidity <70% R.H.
- Enclosure Rating: NEMA 4X Dustproof, Water/Splash Resistant
The meter updates readings at a rate of one time per second. Input protection is rated for 24V dc or 24V ac rms maximum input voltage on any combination of input pins.
Configuration Options
The series offers configurable options regarding channel count, communication interfaces, and accessories:
- Housing & Display: Compact dimensions of 192 H x 91 W x 53 mm D (7.6" x 3.6" x 2.2"). Weight is approximately 255 g (9 oz). Features a backlit LCD with a maximum reading of 1999.
- Power: Operates on one included 9V alkaline battery, providing typical life up to 200 hours. Spare batteries are available as Model No. MN1604.
- Connections: Accepts standard subminiature thermocouple connectors (flat blades spaced 7.9mm center-to-center).
- Sensor Options: Models include a free Type K insulated beaded wire thermocouple with subminiature connector and spool caddy (1 per channel). Spare probes are available, including the KTSS-HH: a 150 mm (6") long, 3 mm (¼") diameter stainless steel Type K probe with a retractable cable expanding to 1.2 m (48").
- Calibration: Optional NIST-traceable calibration is available as HH-NIST (no points) or CAL-3-HH (with points).
Key Product Differences
The series consists of three primary model configurations distinguished by channel count and communication features:
- HH508: Single-channel digital thermometer.
- HH509: Dual-channel digital thermometer with T1-T2 differential input capability.
- HH509R: Dual-channel digital thermometer featuring RS232 communication output in addition to the HH509 capabilities.
All models share the same NEMA 4X enclosure, measurement ranges per thermocouple type, and basic accuracy specifications. The primary functional distinction is the ability of the HH509 and HH509R to measure two inputs simultaneously or calculate differential temperature (T1-T2), whereas the HH508 measures a single input.

Is there an upgrade?
We purchase stab probes that we use in your handheld thermocouples but the probes break often and the jack that the probe connects to within the thermocouple wears out and no longer holds the probes in place and/or gives false readings due to poor connection. We are using probe type 88301K probes and HH508 handheld thermometer. Is there and upgraded version that we could invest in to prevent having to re-order probes and thermometers due to the issues noted above?

Very poor quality
If you need to test temperature with a robust, reliable and accurate unit, this is not it. Where the probe meets the unit is very loose and after a short time taking temperature readings is a nightmare. You have to fiddle with the unit just to get a reading for several minutes with it sometimes not working at all. It is also very slow

HH509 Handheld Digital Thermometer
The HH509 was easy to set up and use. The construction of the unit is of high quality and seems to be quite durable.

How often does the HH508 have to be calibrated.
It is recommended the HH508 be checked for calibration at least once per year and adjusted if out of tolerance.

Does the HH509R Come with a NIST Certification
The HH509R does not come with a NIST certificate standard but is optional. The meter will come with a C of C no charge but is not NIST traceable.

Does this unit come calibrated when purchased?
Thank you for your inquiry. Item# HH508 does not come calibrated. Only Item# HH508-CAL-3 comes with the calibration data.
Date published: 2023-02-17
Display will show type K, J,T, and E but not S. Wondering if when type is not displayed is that S?
The HH508 only has icons to highlight for J,K,T and E and if none of these are illuminated then it is set for type S.

the HH509 meter has a reading without the probe connected and reading 28.2 C constant. tried reset the meter via removing the battery , did not work. it was recently calibrated
The meter appears to be reading the internal CJC continuously which may indicate a short circuit. You can jumper between the + and - on the input and if there is no temperature reading change this is most likely the problem and the unit would need to be returned to repair.

If I were measuring a point of contact temperature- I'm trying to measure the exact temperature of a heating element, what probe might I use, and would this be an acceptable model to use for the above application?
Thank you for your inquiry Textiles. Please send an email to temp@omega.com or call 1-888-826-6342 and describe your application.

What probe lengths are available, and what diameter? I need a probe length of approximately 12-inches, 1/4-inch diameter. Thanks
Probe in the picture is 1/8''. Please see attached link for probe with the specs you are looking for: https://www.omega.ca/en/temperature-measurement/temperature-probes/handheld-probes/jhin-rsc/p/KHSS-14U-RSC-12

The spec's say the meter can resolve 0.1°/1°, but the manual doesn't mention how to change display resolution; how is this done?
The HH509 is a 3 1/2 digit display and will have a 0.1 resolution up to 199.9 then automatically change to 1.0 resolution from 200 degrees and above.
