Product Description


K, J, and T-type Thermocouple Temperature USB Data Logger

This data logger measures and stores over 32,000 temperature readings from either a K, J or T type thermocouple . A thermocouple is attached via the thermocouple socket at the base of the unit. The user can easily set up the thermocouple type, logging rate, start-time, logging mode, and download the stored data by plugging the module straight into a PC’s USB port and running the purpose designed software under Windows 2000, XP, Vista & 7. Data can then be graphed, printed and exported to other applications. 

Each EL-USB-TC data logger is supplied complete with a basic K-type thermocouple (for 0 to 400ºC measurement), long-life lithium battery, which will last for approximately 6 months.

This is a popular part, normally stocked in high quantity and suitable for new designs.

* Using thermocouple sensors, the EL-USB-TC can log temperatures as detailed above, but the data logger should not be subjected to temperatures outside the Operating temperature range
** EL-USB-TC is designed to be used whilst disconnected from USB port
*** @ 25°C and 1m logging rate

The EL-USB-TC is suitable for a wide variety of applications, these include:

– High and low temperature monitoring
– Transportation
– Food & drink
– Building & site monitoring
