General Tools and Instruments IRT659K - Manual (Page 3)

3
The IRT659K can measure surface temperature using either of two methods:
non-contact (using an IR thermometer with a laser pointer) or contact (using a
“K” type thermocouple). A “K” type thermocouple with a wide measurement
range is included in the package. The instrument automatically stores its last
10 IR readings in a nonvolatile memory for later recall in reverse chronological
order. During a single scanning session, the IRT659K simultaneously displays
real-time measurements on a main readout and the maximum, minimum,
average or largest difference between measurements during that session on
a smaller readout.
The IRT659K and “K” type thermocouple, a “9V” battery and this user’s manual
are sold together with a nylon pouch in a blister pack.
