Product Specification


Detailed Product Features and Specification


The EL-WiFi-21CFR-DTC measures the temperature of the environment in which the probes are situated. Featuring industry standard miniature thermocouple
connectors, the device is compatible with K, N, J and T-type probes.

Data is streamed wirelessly over any compatible WiFi network to be viewed on the 21CFR Cloud. During configuration, the sensor will search for an existing wireless network whilst physically connected to the PC. It can then be placed anywhere within range of the network. If the sensor temporarily loses connectivity with the network, it will log readings until it is able to communicate again with the 21CFR Cloud (max 30 days at 10-second sample interval).

The sensor is IEEE 802.11bgn* (2.4GHz) compliant, supports WEP, WPA/WPA2 encryption and enterprise networks (PEAP, TTLS, FAST).

The EL-WiFi-21CFR-DTC has a protection rating of IP40 and the probe tip IP67. The unit is freestanding, but it can be attached to a wall or surface using the bracket provided. The unit can be clipped in and out of the bracket as required.
