Features
The OMEGA™ HH42A digital thermometer is the most recent addition to a series of instruments based upon our high precision temperature measurement system technology.
This instrument provides the accuracy and resolution needed to meet the measurement needs of a precision laboratory or critical process control and testing functions. Free software is included enabling users to start recording, charting, and storing data in a familiar file format on their PC within minutes of opening the box. A well-defined command set and output data format allows users to easily connect computer systems to the thermometer to create custom displays and report formats. There are a wide range of custom designed application specific thermistor probes that can be selected for use with this instrument. The selected probe would be hardwired to the instrument and calibrated together to meet specific high accuracy requirements. Interchangeable probes with plug-in connectors are also offered.

Good Unit
Unit works great when it works. I have problems with the 1/4 inch phono jack on the unit recoginizing the temp probe. It is intermittent and I have to wiggle or re-insert it a couple of times so I can get it to work.

Excellent temperature meter
We have had these units for several years. What is great about them is that I can switch meters and/or probes and the replacements will always read the same to +/- 0.1 C. They really are this good, which means we don't need to do extensive internal calibrations.

Is there a calibration procedure available for the HH42A Thermometer?
The HH42A meter must be returned for calibration as it is an electronic proprietary process.
Date published: 2021-12-22
Is this product RoHS compliant
Yes the HH42A is ROHS compliant.
Date published: 2022-11-18
Are there drivers or documentation to communicate with the HH42A with an end user developed application (C, LabVIEW)?
Omega provides the Software to communicate and Data log with the HH42A and no additional protocols are available. The drivers are accessible from the Software link of the product page.

Hi, the software in link does not has logging capability, is there another software for that?
This is the only Software for the HH42A and has well defined command sets and output data formats.
You can copy data into EXCEL for making graphs and data files.

i am looking to buy Ultra-High Accuracy and Resolution Digital Thermistor Thermometer. Item# HH42A does this model come with probe ?
Thank you for your inquiry! The model does not come with a probe included.
Date published: 2023-01-19
What is the accuracy of this by itself? The datasheet says that there is an accuracy up to +/-0.015 °C and +/-0.02°C. I imagine the accuracy is really in Ω.
The HH42A accuracy is +/-0.02C worst case over it's measurement range for the meter only and the probe accuracy would need to be added. For further questions contact the Temperature Engineering group at temp@dwyeromega.com.

Will this Thermometer work with the HSTH-44033-40-PP and the HSTH-44033-120-PP?
Yes, the 44033 thermistor element (2252 ohm) is compatible with the HH42A meter which accepts the 2252 ohm thermistors.
Date published: 2019-12-14
The thermistor probe is already included in the total price of this unit?
Thank you for your inquiry. No Probe Included.
