Product Overview
Temperature control is a critical requirement in many industrial environments such as factories, warehouses, cold storage areas, and technical rooms. A small temperature change can directly affect product quality, equipment performance, and storage safety.
The AT-TMS3.1 is an industrial temperature monitoring device designed to measure and display temperature values in real time. With a compact structure, clear LED display, wide measuring range, and optional RS485 Modbus communication, it is a practical solution for indoor temperature supervision.

Overview of AT-TMS3.1 Temperature Monitor
The AT-TMS3.1 is a digital temperature monitor that provides continuous temperature readings through an LED display. Unlike handheld thermometers, this device can be installed permanently in a specific location, allowing operators to monitor temperature conditions easily without manual checking.
This model is suitable for industrial indoor environments where stable temperature monitoring is required.
Key Features
The AT-TMS3.1 is designed for stable temperature monitoring in industrial indoor environments. With a clear LED display, wide measuring range, and optional RS485 Modbus communication, this device supports continuous supervision and helps reduce temperature-related risks in factories and storage areas.
Red LED Display
The device uses a red LED display, making temperature readings easy to see in industrial working conditions similar to large-format temperature humidity displays.
Wide Temperature Measuring Range
AT-TMS3.1 supports a wide measurement range, making it suitable for many industrial applications:
- Temperature range: -40°C to +125°C
· High Resolution and Accuracy
For stable monitoring, the device provides:
- Resolution: 0.1°C
- Accuracy: ±1°C
This ensures temperature values are displayed clearly and consistently.
Optional Modbus RTU RS485 Communication
The AT-TMS3.1 supports Modbus RTU RS485 communication (optional), allowing integration with PLC or SCADA systems for centralized monitoring and data logging.
Standard Power Supply and Protection
The device operates using standard industrial power:
- Power supply: 100–240V AC, 50/60Hz
- Protection rating: IP50
It is designed for indoor use in industrial environments.
