The ARTM-24 is a 24-channel temperature measuring instrument designed for comprehensive thermal monitoring of electrical equipment. It supports multiple sensor types including NTC thermistors (10kΩ to 100kΩ), PT100/PT1000 three-wire RTDs, and K/T/J/E/N thermocouples, covering measurement ranges from -200°C to 1372°C. The device features DIN35mm rail mounting, dual independent relay outputs for AL1/AL2 alarm functions, and RS485 communication via Modbus-RTU protocol for seamless industrial integration. Each channel offers individual enable/disable control and configurable high/low temperature thresholds with hysteresis settings through dedicated debug software. Optional wireless communication extends flexibility while an integrated ambient temperature/humidity sensor provides environmental context. With wide auxiliary power support (AC/DC 85-300V or DC 12-30V) and ±1°C measurement accuracy, the ARTM-24 is ideal for continuous temperature surveillance in transformer windings, motor bearings, and low-voltage electrical connections.
