Lascar Brand: Lascar
This data logger has been designed to interface with either a J, K or T type thermocouple, which is simply connected to the dedicated socket at the base of the unit. The unit is easily set-up by plugging into a PC, via the USB port, where parameters such as mode, logging rate, start time, and any downloads may be done.

The instrument will record over 32,000 readings at a rate of between 1 second and 12 hours and, when downloaded, data can be graphed, printed and exported to other applications via the supplied purpose designed software.
