Good value industrial sensor
Does exactly what it says. The response time is quick enough for our HVAC control loop. Would have given 5 stars if the cable entry had a better strain relief mechanism.

Accurate and reliable
Great sensor for the price. Calibration seems spot on when compared to our reference meter. Only minor issue is the mounting bracket could be slightly more robust, but it works fine on drywall.

Easy setup with Modbus
As an automation engineer, I appreciate devices that just work. The Modbus register map is standard and documented well. Had it up and running in under 20 minutes.

Excellent build quality
The casing feels very durable and professional. We are using this in a greenhouse environment where humidity is high, and it has performed flawlessly for two months so far.

Perfect for our server room monitoring
We installed three of these units in our data center. The RS485 integration was seamless with our existing BMS system. The LCD display is clear and easy to read from a distance.

Clear display and precise readings
Bought this for a pharmaceutical storage area. The precision meets our internal compliance needs, and the large digits on the screen make manual logging easy during audits.
Q: What is the refresh rate of the LCD display?
A: The LCD updates approximately every 2 seconds to ensure stable readings while still providing near real-time data.
Q: Is the sensor probe replaceable if it drifts over time?
A: The sensor element is integrated into the main housing for better protection against dust and moisture. If calibration drifts significantly, the entire unit typically needs replacement or factory recalibration.
Q: Does it come with a DIN rail clip or is it wall-mount only?
A: The package includes a mounting bracket for wall installation. For DIN rail installation, an optional adapter clip is available separately or can be 3D printed using the dimensions in the manual.
Q: Does this device support multiple drop addresses on the same RS485 bus?
A: Yes, the CWS19 supports configurable Modbus addresses from 1 to 247, allowing multiple units to communicate on a single bus pair.
Q: Can this be powered by a standard 24V AC transformer?
A: No, the CWS19 requires a DC power supply between 12V and 24V. Please ensure you use a rectified DC source to avoid damaging the unit.
