💡 Description
GT-AT0637 Wireless Smart Pressure Monitor integrates pressure and gas monitoring for multi-scenario industrial use. It offers customizable pressure ranges (0-35kPa/0-600kPa) and gauge pressure, with ±0.5%F.S accuracy, and detects methane (0~100)%LEL with ±2%LEL accuracy via a laser sensor. Powered by a DC3.6V battery, it has a five-year typical life, with adjustable pressure sampling (30~60s) and methane sampling (15~30min) intervals, and 6-hour adjustable heartbeat interval. Equipped with LCD display, 4G/NB-IoT customizable transmission, and magnetic switch, it supports remote management, switch quantity control, and real-time power outage alarm. With explosion-proof protection, wall-mounted installation, customizable process connections, and -40°C~70°C operating temperature, it meets integrated monitoring needs with high stability.
