Accurate real-time measurement with flexible outputs, Modbus communication and compact wall-mount design for easy installation.
Note: All Tongdy monitors and controls ship direct from the factory. Please allow 10-15 business days for shipping and handling.
RS485 interface with Modbus RTU supports seamless system compatibility. Analog outputs (0–10 VDC, 4–20 mA, 0–5 VDC) expand its flexibility. The accompanying mobile app offers data visualization, display, and download functions, complemented by a six-light, three-color indicator that clearly communicates environmental conditions. This transmitter consolidates sensing, recording, and networked monitoring into a single, reliable solution for professional applications.
