The HH800 and HH801 handheldsare easy to use Type K inputthermocouple thermometers.Both feature a large 31/2 digit LCDwith a maximum reading of 1999.The HH800 is a single-input modelwhile the HH801 has two inputs andallows for display of T1, T2 or .T(T1-T2). Both models feature T/Coffset adjustment and are °C/°Fswitchable. The HH800A andHH801A offer most of the featuresof the HH800 and HH801, butboth also have data storagecapability and accept J or K Typethermocouples. The HH801B andHH801C offer most of the featuresof the HH801, but they accept fourdifferent thermocouple types. Bothunits feature settable Hi/Lo limitsfor both inputs and have an integralalarm beeper. The HH801Balso features three displays forsimultaneous viewing of bothinputs and the differential.

Rated 5 out of 5 by from Quick & Efficeint Delivery We were on a tight schedule to receive the HH800 at our facility. We didn't have any issues with timeliness and are very appreciative of Omegas quick & reliable services. The HH800 successfully met it's function & has not seen any quality issues.

The spec sheet and manual have different accuracies. Which is correct? Spec sheet shows ±0.1% rdg + 1C for the entire range. Manual shows a decrease in accuracy to ±0.1% rdg +2C when below -60. There are other small discrepancies as well.

Asked by: BenjaminSLC
The HH801B has a resolution of 0.1C over the full range and the accuracy is +/-0.1% of reading +1C for -60 to 1372C and +/-0.1% of reading +2C between -220 to -60C. There a several models on the data sheet so send a request for information to concerning a specific model.

Is cold junction compensation temperature sensed directly at the k-type input (ala Fluke 54 and 80TK), or with an internal temp sensor not located on the jack?

Asked by: Anonymous
Thank you for your request. The internal temperature sensor is not located at the input connection.

Does this meter come with any connectors or leads? Which of your connectors/leads would be most suitable to connect to a kiln type K thermocouple. I will be using it to verify temperatures in a knife heat treating kiln.

Asked by: MG35
Thank you for your inquiry. The HH800 series thermocouple meters only come with a beaded Type K thermocouple with a connector (one per channel). For any further questions, please email us at or call 1-888-826-6342.
