-50°C to 110°C (-58°F to 230°F). Measurement Accuracy: ±0.1°C. Sensor Type: NTC (10K 0.5%) waterproof thermistor probe.
A: The module itself has a theoretical measurement range of . However, the final achievable range and accuracy are strictly determined by the limits of the NTC thermistor you attach to it.
The NT18B07 is a powerful and flexible tool for adding multi-channel temperature monitoring to any system that speaks Modbus RS485. By adhering to the specifications outlined in this manual—using the correct B3950 10K 1% NTC thermistors, properly configuring the RS485 network and unique module IDs, and correctly interpreting the scaled Modbus data—you can leverage this module for reliable and precise temperature acquisition across a vast range of applications.
Supports up to 247 modules via A0-A5 modification (default address depends on model). nt18b07 manual
