Perfect for our warehouse monitoring

We installed six of these units across our cold storage facility. The RS485 integration was seamless with our existing SCADA system. Readings are consistent and the IP65 rating gives us peace of mind in humid conditions.

Excellent for greenhouse automation

Using these to control ventilation fans in our commercial greenhouse. They handle the high humidity spikes without drifting. The response time is quick enough for our automated controls.

Best choice for HVAC logging

We replaced our old analog sensors with these digital transmitters. The data stability is impressive, and we no longer have noise interference issues on the long cable runs.

Reliable and accurate

Compared this against a calibrated handheld meter, and the deviation was negligible. The wall-mount design is sturdy and looks professional in our server room.

Good product, fast shipping

The sensor arrived well-packaged. Setup took about 10 minutes per unit. Only minor issue is the cable gland could be slightly larger for thicker conduit cables, but manageable.

Solid industrial sensor

Very robust build quality. The documentation for the Modbus registers could be slightly clearer, but once configured, it works flawlessly. Great value for an industrial-grade transmitter.

5 FAQ

Q: Do you provide a configuration tool or software?

A: We provide a free Windows-based configuration utility available for download on our official website. It allows you to read real-time data, change addresses, and adjust sampling rates.

Q: Can this be powered by 24V AC directly?

A: Absolutely. The unit has a wide power input range supporting both 12-24V DC and 12-24V AC, making it versatile for various industrial power supplies.

Q: What is the default baud rate out of the box?

A: The factory default settings are 9600 baud, 8 data bits, no parity, and 1 stop bit (9600, 8, N, 1). These can be easily changed via software commands if your system requires different settings.

Q: Is the probe replaceable if it gets damaged?

A: The sensing element is integrated into the housing to maintain the IP65 rating. If the sensor fails, the entire unit typically needs replacement to ensure calibration integrity and weatherproofing.

Q: Does this sensor support daisy-chaining multiple units on one RS485 line?
