Data Loggers (by model)

Our Products

Data Loggers

Lascar's data loggers are used the world over in a diverse range of applications: monitoring fridge temperatures for vaccines, measuring carbon monoxide levels or recording the environmental conditions a package is subjected to during shipping.

Temperature / Humidity / Dewpoint Monitoring

EasyLog temperature data loggers ( USB-1, USB-1-PRO, USB-TC, USB-TC-LCD, USB-LITE) & temperature & humidity data loggers ( USB-2, USB-2+, USB-2-LCD, USB-2-LCD+,USB-RT) are used to build up a picture of the environmental conditions throughout a building or complex. This can help ensure correct operation of heating or air-conditioning equipment, or that a warehouse is providing the correct storage environment for your stock.

Server Room Monitoring

The various servers, hard-disks and routers located in the server room form the heart of a modern company - when the network is down, your business is down. The EasyLog USB-RT is designed to provide you with an early warning should temperatures in your server room start to rise too high. Linked to the network via USB these devices can send email alerts when temperatures exceed a preset temperature limit.

Carbon Monoxide Monitoring

The USB-CO is a USB data logger that measures and stores up to 32,510 Carbon Monoxide (CO) readings over a 0 to 1000 ppm measurement range.

The low cost, and compact design of the EasyLog range make them an excellent choice for this application, where a number of data loggers may be needed across a site.

All USB data loggers come with the EL-WIN-USB software for setup, data logging, and graphing:

* with battery supplied, 10 minute logging rate, 25°C ambient temperature, audible warning disabled, reading <10ppm CO

** Data is stored in a log file, which can store up to 7 day’s worth of data. This data is overwritten at the beginning of each new logging session. The software provides the option for the user to save the data permanently to the hard-drive.
