Both comestandard with a built in USB portand DC power jack. OptionalWindows software and AC adapterallow real time data logging to PCfor extended periods. The HH804Wmodel features aquick and easy to use wirelessinterface instead of USB. Thisallows real time data transmissionat distances of up to 75'.

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 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.

Rated 4 out of 5 by from 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?

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.

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.

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?

Asked by: JayF
Yes! It's at https://www.omega.com/en-us/sensors-and-sensing-equipment/temperature/hygrothermometers/p/HH800-ADAPTOR

Where can I find the protocol or functional description of the USB connection, or software app, please? Thanks.

Asked by: JayF
The HH804U uses the HH800-SW Software which is purchased separately and includes the communication cable.
