Networked environmental facility safety and automated alarming reach absolute stability when using the Comet H4531 wall-mounted web thermometer module. This single-channel tool features an integrated internal temperature sensor covering a stable -30 to +80 °C measuring range with high precision. Driven by an external 9 to 30 VDC power structure, it automatically updates a dual-line LCD layout while managing two independent on-off power relays over a native Ethernet 10/100 communication bus line.
