Twelve channel hand-held indicator/data logger with a large, easy-to-read, backlit LCD display (82mm x 61mm). Selectable between Thermocouple inputs K, J, T, R, S and E. Save up to 12 different temperature measurements concurrently with date and time information (year, date, minutes, seconds) and selectable sampling rate (automatic or manual: 1 second to 1 hour).

The HH-4208SD incorporates a page-select function and is capable of showing up to 8 channel readings on the screen at one time (CH1 to CH8 or CH9 to CH12).

Data can be logged in two ways:

Software: Data can be logged in real-time using the optional Data Acquisition software (HH-4208SW) with the unit connected to a PC via the USB or RS-232 cables*. Data is saved to the computer in .mdb (Microsoft® Access) database format which can then be imported into Microsoft® Excel.

SD Card: A 4GB SD memory card is supplied for storage of logged data without the need for additional software. Data is saved to the card in .xlsx (Microsoft® Excel 2007 onwards) format. The card can then be plugged into a reader to retrieve the data. The SD card cannot be used with the Data Acquisition software. The 4GB SD card can store in excess of 30 million records.

The HH-4208SD is powered via 8 AA batteries or the optional mains power adaptor, and is enclosed within a rubber protective case.

Supplied with 4GB SD card (max 16GB), instruction manual and carry case.
