Great accuracy, manual could be better

The sensor itself is excellent and very precise. The LCD is easy to read even in low light. I deducted one star because the wiring diagram in the manual was a bit small, but once figured out, it works flawlessly.

Perfect for our server room monitoring

We installed three of these units in our data center. The RS485 integration with our existing SCADA system was seamless. The readings are stable and match our calibrated reference instruments perfectly.

Reliable and consistent

Been running this for six months in a greenhouse environment. Despite the high humidity fluctuations, the sensor has not drifted. Very happy with the purchase.

Good value for industrial use

Compared to other brands costing twice as much, this performs just as well for general industrial monitoring. The response time is quick enough for our HVAC control loop.

5 FAQ

Q: Can this be powered by a standard 24V AC transformer?

A: Yes, the device supports a wide voltage input range of 10-30V DC or 24V AC, making it compatible with most standard industrial transformers.

Q: What is the maximum cable length for the RS485 connection?

A: Using standard shielded twisted pair cable, you can achieve reliable communication up to 1200 meters (approx. 4000 feet) at lower baud rates.

Q: Is the sensor probe replaceable if it gets damaged?

A: The sensor element is integrated into the housing for better protection and calibration stability. If the unit fails, the entire device should be replaced to ensure accuracy.

Q: Does it come with a calibration certificate?

A: Standard units include a factory test report. If you require an ISO-traceable calibration certificate, please select that option at checkout or contact sales before ordering.

Q: Does this device support logging data internally without an external computer?

A: This specific model acts as a real-time transmitter via RS485. For internal data logging without a host, please check our standalone data logger series which includes SD card slots.
