The Lascar Electronics EL-WIFI-ULT WiFi Ultra Low Temperature Cryogenic Vaccine Data Logger with Display is designed to monitor vaccines in cryogenic dry ice storage and transit. The measurement range is -100 to +100°C (-148 to +212°F) using the probe supplied with the logger. The logger automatically records data and uploads it to the EasyLog Cloud via a standard wireless network; the data can be viewed on a PC using free software or the EasyLog Cloud, or on a mobile device using the EasyLog Cloud App.

To configure the EL-WIFI-ULT data logger for use on a given wireless network, either connect it via USB to a PC running EasyLog WiFi software on the network, or configure wirelessly using the EasyLog Cloud app on a mobile phone with access to the network. The logger can then be placed anywhere within range of the network. If the logger temporarily loses connectivity with the network, it will log readings until it is able to communicate again with the PC application or EasyLog Cloud (max 30 days at 10 second sample interval).

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

The EL-WiFi-ULT has a protection rating of IP40. The unit is freestanding, but can be attached to a wall or surface using the included bracket. The unit can be clipped in and out of the bracket as required.
