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.

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.

Accurate thermometer but probes are a problem!
The RTD probes are very difficult to solder to the connectors!

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.

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.

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.

Good value, overall.
Soldering the extension wires to the probe connector was a bit of a challenge, but the finished product performs as expected.

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

DOES THIS COME WITH PROBES? IF NOT WHAT PROBES CAN YOU USE WITH THIS MODEL? I NEED TO MEASURE -80°
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 (https://www.omega.com/en-us/temperature-measurement/temperature-probes/probes-with-lead-wires/pr-10/p/PR-10E-4-100-1-8-6)

What is the part number for the USB cable for HH804U
Hi Davy,
Software and cable are sold as a set only; HH800-SW.
Best regards

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!
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.

is this product support windows 10? if so, I will buy right away.
The current version of HH800-SW is compatible with Windows 10 operating systems.

Is there publicly available calibration documentation ?
You can contact the Temperature Engineering group at temp@omega.com to access the calibration procedure.

How often does the HH804 unit need or recommended to be calibrated?
Hi, thanks for your question. We recommend a yearly calibration for the HH804. Please contact our Tech Support if you have any further questions. Thank you!

Do you sell an AC adapter for the HH804U, to plug into its 12Vdc power jack? If not, can you give me the size of the plug that fits that jack?
Yes! It's at https://www.omega.com/en-us/sensors-and-sensing-equipment/temperature/hygrothermometers/p/HH800-ADAPTOR
