This data logger measures and stores up to 16,382 relative humidity and 16,382 temperature readings over 0 to 100%RH and -35 to +80°C (-31 to +176°F) measurement ranges. The user can easily set up the logging rate and start time, and download the stored data by plugging the module straight into a PCs USB port and running the purpose designed software under Windows 2000, XP, Vista and 7. Relative humidity, temperature and dew point (the temperature at which water vapor present in the air begins to condense) data can then be graphed, printed and exported to other applications.

The data logger is supplied complete with a long-life lithium battery, which can typically allow logging for a year. Status indication is via flashing red and green LEDs. The logger is protected against ingress from water and dust to IP67 standard when the plastic cap and seal are fitted.

* Depending on sample rate, ambient temperatures and use of alarm LEDs
** This specifies the overall error in the logged readings, for relative humidity measurements between 20 and 80%RH
*** This specifies the overall error in the calculated dew point, for realtive humidity measurements between 40 and 100%RH at 25°C

LED Flashing Modes

EL-USB-1 features 2 bi-colour LEDs; one LED represents temperature measurement, the other represents RH. Each is clearly marked on the logger. To save power, the status indicator alternates between the two channels every 10 seconds. First you will see the status of the temperature logging and 10 seconds later you will see the status of the RH logging and so on.

EL-WIN-USB (Control Software)

Lascar's EasyLog USB control software is supplied free of charge with each data logger. Easy to install and use, the control software runs under Windows 2000, XP, Vista & 7. The software is used to set-up the data logger as well as download, graph and export data to Excel.

The software allows the following parameters to be configured:

Logger name (up to 16 characters)

°C or °F

Logging Rate (10s, 1m, 5m, 30m, 1hr, 6hr, 12hr)

High and low alarm levels

Start date and time
