1. Product overview
WS-885 is an alarm temperature adjustable temperature detector (hereinafter referred to as the detector). The detector adopts a precise and reliable thermal sensor. When the ambient temperature rises to the alarm temperature value you set, the detector will generate an alarm, and Transmit the alarm signal to the alarm controller. The product uses a digital tube to display the real-time temperature. The alarm temperature can be set from -10°C to +90°C. This product can be used in computer rooms, warehouses and other places that require real-time monitoring of the ambient temperature.
