The EL-WiFi-VACX measures the temperature of a probe fitted within a glycol-filled bottle, designed to mimic the temperature response of vaccine samples. Data is streamed wirelessly over any compatible Wi-Fi network and can be viewed on any internet-enabled device, via browser or free mobile app.
Device setup and connection to a Wi-Fi network and the EasyLog Cloud are simple, just download the free EasyLog WiFi PC software or the free EasyLog Cloud mobile app and follow the device setup wizard. The device can be placed anywhere within range of the Wi-Fi network. If the device temporarily loses connectivity with the Wi-Fi network, it will log readings until it is able to communicate again with the 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-VACX has a protection rating of IP42, and the probe IP67. The device is freestanding, but can be attached to a wall or surface using the bracket provided, and clipped in and out of the bracket as required. This device is equipped with a translucent back to show a red flashing indicator when it is in an alarm state as well as a moderate volume sounder to alert anyone in close proximity.

Battery Life and Power Supply
The battery can be recharged (unit must be between 0 – 40°C) via a PC, a USB +5V wall adapter, or a portable USB battery pack using the USB lead provided. It can also be permanently powered by a USB wall adapter or USB battery pack. Readings may be affected while the internal battery is being charged. However, once charged, continued connection of the charger will have no effect.
Battery life is dependent on: transmission period, WiFi encryption method, WiFi encryption key rotation frequency (determined by the router/access point), signal strength between router/access point and WiFi device, presence volume and type of WiFi traffic from other devices, sample rate and operating temperature.
EL-WiFi-VACX is easy to set up and connect to the EasyLog Cloud. Use the EasyLog WiFi software for PC* or the EasyLog Cloud app available from Google Play or on the App Store. A free acount is available for 1 to 4 devices.
