High precision as advertised
We needed high accuracy for a pharmaceutical storage area. This sensor maintains consistent readings even with fluctuating airflow speeds. The 4-20mA output is noise-free over long cable runs.

Solid build quality
The stainless steel probe feels very durable. Setup was straightforward using the DIP switches for output selection. Only giving 4 stars because the manual could be clearer on the wiring diagram for 4-wire setups.

Great value for industrial use
Compared to other brands costing twice as much, this performs just as well. The response time is quick enough for our control loop adjustments. Highly recommend for facility managers.

Reliable performance
Been running these for six months now without any drift. The housing seals tightly into the duct preventing leaks. Would prefer if it came with a longer mounting flange option, but overall very satisfied.

Perfect for HVAC integration
Installed three of these in our commercial building's main ducts. The RS485 communication is stable and the Modbus registers were easy to map to our BMS. Readings match our handheld calibrator almost exactly.

Easy configuration
Configuring the address for the RS485 network took less than five minutes. The data logs show consistent temperature and humidity tracking. Excellent product for the price point.
Q: Is the probe replaceable if it gets damaged?
A: The probe element is integrated into the transmitter housing for better sealing and accuracy. If the probe is damaged, the entire unit typically needs replacement to maintain calibration integrity.
Q: Does the RS485 output support Modbus RTU protocol?
A: Yes, the RS485 interface uses the standard Modbus RTU protocol. You can read temperature, humidity, and dew point values via specific register addresses detailed in the user manual.
Q: Can this sensor be used in pipes with high velocity air flow?
A: Yes, the sensor is designed for duct installations and can withstand air velocities up to 20 m/s. Ensure the probe is inserted correctly according to the installation guide for accurate readings.
Q: Can I switch between 0-10V and 4-20mA outputs on the same unit?
A: Yes, the output signal type can be selected via the internal DIP switches or jumper settings before installation. Please refer to the wiring diagram inside the cover to set your desired output.
Q: What is the power consumption of this unit?
A: The typical power consumption is less than 1W when operating at 24V DC. Please ensure your power supply can handle the total load if connecting multiple units in parallel.
