EL-WiFi-ULT+
High Accuracy, Ultra-Low Temperature
Cryogenic Vaccine WiFi Data Logger
- Measurement range -100 to +100°C (-148 to +212°F)
- High accuracy T-type probe on 2m cable
- Dual-channel recording through two external thermocouple probes
- Wirelessly stream and view data on the EasyLog Cloud, App, or on a PC
- View and analyze multiple sensors, including graphing of historic data
- Configurable high and low alarms with indicator
- Easy sensor set-up using free PC software or App
The EL-WiFi-DULT+ is designed to monitor vaccines in cryogenic dry ice
storage.
Data is streamed wirelessly over any compatible WiFi network and can be viewed
on a PC using free software or on the EasyLog Cloud or App.
To configure the sensor 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 sensor 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 PC application or
EasyLog 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).
EL-WiFi-DULT+ has a protection rating of IP40. The unit is freestanding but
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.

CALIBRATION
CERTIFICATES ARE NOW AVAILABLE
Lascar now offers a Traceable Calibration Certificate Service on Temperature
Data Loggers. Using reference equipment that has been calibrated by a
UKAS/NIST accredited laboratory and using apparatus traceable to national or
international standards. For more information please see
www.lascarelectronics.com.
Easy log Software
Lascar’s WiFi software* is available as a free download from:
www.lascarelectronics.com/software/easylog-
wifi. Easy to install
and use, EL-WiFi-WIN allows easy connection of sensors to a WiFi network. The
user can select where data is stored – the PC or the Cloud.
When setting up your logger, make sure you select the T-Type probe.
EasyLog Cloud
Your Data. Anytime. Anywhere.
EasyLog Cloud harnesses the power of loT to automate data logging and alert
notifications, enabling you to monitor and manage multiple data logging
devices in different locations completely remotely. The system easily scales
to meet your needs. Perfect for compact systems with just a few measuring
points, or corporate solutions with thousands of devices around the globe.
You will
need to create an account at
www.easylogcloud.com before setting up your
cloud-connected data logger.

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, the 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, the
present volume, and type of WiFi traffic from other devices, sample rate, and
operating temperature.
