Perfect for industrial monitoring
Installed this in our warehouse HVAC system. The 4-20mA output integrates seamlessly with our existing PLC controllers. Readings are stable and match our calibrated reference meter.

Solid build quality
The housing feels robust and the IP65 rating gives me confidence for outdoor use. Setup took about 20 minutes including configuration of the Modbus address.

Good value, easy setup
The RS485 wiring was straightforward using the provided pinout diagram. Accuracy seems solid for the price point. Only minor issue was the cable gland could be slightly tighter.

Excellent precision
Compared this against a certified lab instrument and the deviation was negligible. Great choice for applications requiring consistent analog signals over long distances.

Reliable data logging
Been running this sensor in a greenhouse environment for three months now. No drift detected yet. The stainless steel probe holds up well against high humidity conditions.

Works as advertised
No complaints here. It provides real-time temperature and humidity data without lag. The support team was also helpful when I had questions about the register map.
Q: Is the probe replaceable if it gets damaged?
A: The probe is integrated into the unit for better sealing and accuracy. If damaged, the entire unit typically needs replacement to maintain calibration integrity.
Q: How do I change the Modbus address?
A: You can change the Modbus address via software configuration tools using the default address, or by sending specific write commands to the holding registers as detailed in the manual.
Q: Does it come with a mounting bracket?
A: Yes, the package includes a stainless steel mounting bracket and screws for easy wall or duct installation.
Q: Can this sensor operate on a 12V power supply?
A: Yes, the device supports a wide voltage input range from 12V DC to 24V DC, making it compatible with standard industrial power sources.
Q: What is the maximum cable length for the RS485 connection?
A: Under ideal conditions with proper shielding and termination, RS485 can support cable lengths up to 1200 meters at lower baud rates.
