Just plug the temperature sensor into an RJ-45 port on the AlertWerks ServSensor and the ServSensor detects it automatically. Never needs calibration. A built-in graph option includes on the sensor graphs temperature variations over a period of time. Has its own SNMP OID so it can collect data over a network and graph it using an external application such as MRTG. Can be read using the included SNMP utilities to allow graphing and data logging at 0.5° C resolution.
