Product Introduction
Imported sensors are used, with temperature accuracy up to ±0.4°C and humidity accuracy up to ±2%RH, ensuring stable and reliable performance.
It adopts a large-size panel and red high-brightness digital tubes, and can display clearly during the day, at night, and even under strong light. The perpetual calendar model has a visible distance >15m, and the temperature and humidity model has a visible distance >35m.
The frame uses high-hardness aluminum alloy, making it sturdy and reliable.
The product adopts a 485 communication interface, standard ModBus-RTU communication protocol, communication address and baud rate are configurable, with a maximum communication distance of 2000m.
10-30V DC wide voltage power supply.
The upper and lower limit values and hysteresis values for alarms can be set.
Statically displays temperature, humidity, and time to prevent flickering in recorded images.
Exceeding the limit can be alarmed through sound and light alarm (optional)
