Excellent value for money

Compared to other industrial sensors we looked at, this offers the best balance of price and performance. The Modbus communication is fast and reliable.

Easy installation

The wiring diagram was clear. Mounted it on the wall of our pharmaceutical storage room. It has been running stable for three months now with no drift in readings.

Reliable for agriculture use

Good sensor for monitoring barn conditions. The IP65 rating holds up well against dust and occasional water spray during cleaning. Wish the cable was slightly longer out of the box.

Industrial grade quality

Replaced our old analog gauges with these digital transmitters. The precision is noticeably better, and being able to log data remotely saves us hours of manual checks every week.

Perfect for our cold storage facility

We installed six of these units in our cold storage warehouse. The RS485 integration with our existing SCADA system was seamless. Readings are consistent and the display is bright enough to see in dim lighting.

Great accuracy, sturdy build

Using this in a commercial greenhouse. It handles the high humidity very well without fogging up. The only reason for 4 stars is that the manual could be more detailed regarding address configuration.
