Product Specs

This product is no longer available and has been superseded by the OS-MINUHUB series.

Rated 3 out of 5 by from Poor support if you don't buy the add-on screen The manual doesn't instruct you on how to use the device with something like a Modbus RTU to USB converter. It also doesn't include the wiring diagram color code for the unit. Lastly, the manufacturer of the sensor is in the UK (this makes them hard to reach) and has not given register information to Omega either. With a support person from Omega I was able to eventually get the sensor working, but it was frustrating that the sensor is offered by itself but not supported at all.
