Rated 1 out of 5 by from Connectors are an issue!! Connectors require DIN probes. Only a couple of probes are capable of being purchased with the correct DIN probes. No adapters exist. You'll be soldering these and hoping they work. And you won't be able to use the style of RTD probe which best suits your application.

Rated 2 out of 5 by from Difficult connectors Stupid me. The other reviewer warned that the connectors are difficult to solder to the RTD leads. Well, I verified that for myself. I regret buying this device because of that. A good solder connection is critical for proper temp measurement, as well as to keep the conductors from pulling loose during use. Too bad, as the device itself would probably work fine.

Rated 3 out of 5 by from Accurate thermometer but probes are a problem! The RTD probes are very difficult to solder to the connectors!

Rated 2 out of 5 by from No longer CE compliant! Really?!! Meter works great & seems to be quite accurate; however, this item was just designated as "No longer CE compliant". This should be documented somewhere! We planned to give these to our service technicians in Europe, but without CE compliance, it might be held up at customs. Seeking new meter now...

Rated 5 out of 5 by from Robust Travel Thermometer Our company relies on accurate and precise temperature measurements. This thermometer has been bumped around in a tool case, traveled hundreds of miles, and continued to provide results we can count on. An easy to understand user interface and long lasting battery makes this a great tool for those who rely on great results.

Rated 4 out of 5 by from Good unit This unit is a good bang for the buck. The only thing I would change is adding another digit of resolution. Make sure you are good at soldering, the connectors can be a bit tricky.

Rated 4 out of 5 by from I love this meter If you know that you soldier skills are lacking do not buy this meter. I did not have any issue with putting the connector on and have bought about three of these meters. You cannot beat this meter for the price. The connectors were a non issue for me and others that I recommend to purchase.

How do/can you retrieve readings off the HH804 that doesn't have a USB option?

Asked by: KMehne
The HH804 does not have any internal memory for data storage and there isn't an output connection to link to your PC or Laptop so you cannot data log on this meter.

Asked by: Benchmark
Thank you for your inquiry! Unfortunately, the HH804U does not come with probes. The PR-16-2-100-1/16-6-E-HH804 is a handheld probe with the HH804U connector. The PR-10 can also be configured to have this connector on the product page (

If I want to use this with a flexible RTD sensor, will an HH804 connector type allow for easy use without soldering? (Specifically used with product # HSRTD-3-100-A-40-E-HH804-CONN)

Asked by: Achilles88
Thank you for your inquiry. Soldering is the only way to attached the HH804-CONNECTOR to a RTD.

What is the part number for the USB cable for HH804U

Asked by: DAVY
Hi Davy, Software and cable are sold as a set only; HH800-SW. Best regards

Does the HH804U need to be connected to computer while collecting data to keep record values? Or can you access recorded values after collecting temperature?

Asked by: Msna
The HH804U does not have any internal memory storage so to collect data you would need to be connected to a Computer via the USB cable and have the Software loaded and running.

What software does the Omega HH804U with USBD connector need in order to transfer data onto the connected computer?

Asked by: Ew0809
The HH804U uses the HH800-SW Software to transfer data to PC's and Laptops.

Will you provide the communication protocol (or VI) that allows accessing meter readings using Labview. I've search forums & found partial code but haven't been successful. Doing this is VALUE ADDED & streamlines integration with test setups!

Asked by: ValueAdded
Omega will provide the HH800 series protocol upon request but does not offer technical support in writing code or debugging issues that may arise. Omega sells the HH800-SW Software to use in collecting data from the HH804U.
