Product Description

High Accuracy WiFi Data Logging Sensor with external Thermistor Glycol Probe. Includes Fridge/Freezer Calibration Certificate.

Model: EL-WiFi-TP+-PROBE-G

Lascar Electronics has paired it’s powerful thermistor probe data loggers with glycol bottle probes for users who need a complete vaccination temperature monitoring system.

Exceeding CDC guidelines for data loggers used in vaccination storage, these units come with an external thermistor glycol bottle – allowing for discrete and continuous temperature monitoring of vaccines. EL-WiFi-TP+-PROBE-G also includes a traceable calibration certificate.

The EL-WiFi-TP+ sensor measures the temperature of the environment in which it is situated. This high accuracy version is accurate to ±0.1°C. Data is streamed wirelessly over any WiFi network and can be viewed on a PC using our free software package or on the EasyLog Cloud service. 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.

The EL-WiFi-TP+ is a low powered battery device. When configured using typical transmission periods (e.g. once every 5 minutes) the sensor will operate for over one year (at room temperature). The battery can then be recharged via a PC or USB +5V wall adapter using the USB lead provided or can be permanently powered by the USB wall adapter.

The software installed on the PC will allow set-up, data logging and data review. Set-up features will include sensor name, °C/°F, sample rate, and high/low alarms. Once configured, historic data can be viewed via the graphing tool or exported into Excel. This software is available to download for free from www.easylogwifi.com.

The sensor is a freestanding unit, however, it can be attached to a wall or vertical surface using the bracket and screws/sticky pad provided.
