4 Channel Thermocouple Data Logger

Product Code: HH-520

Easy to use, high accuracy, hand-held thermocouple data logger with four input channels. Powered by batteries or USB.

Simply connect your thermocouple sensor(s) using a miniature flat-pinned plug. Selectable between thermocouple inputs K, J, T and E.

All four input channels are shown on the screen at once, identified as T1, T2, T3 and T4, with the ability to also show T1-T2 differential.

The data logger can store/recall up to 100 manual data logging 'spot' readings, or over 16,000 readings per channel in automatic logging mode. An alarm on channel 1 (T1) can be configured to audibly alert if the temperature exceeds a high or low limit.

Install the free Windows software on a PC and connect to the data logger using the supplied USB cable. The software can retrieve historical logged data or perform real-time logging on-screen; data can be printed, graphed and exported in .csv, .txt or .ghf format (.ghf format for use only with the software). Exported files can be loaded into the software or other applications such as Microsoft® Excel.

This product can be supplied with a calibration certificate. Contact sales for further information. This product can be supplied with a calibration certificate. Contact sales for further information.
