The Differential Temperature Data Logger records and logs temperature readings with 2 type K thermocouple probes and an IR thermometer probe. The infrared probe can be used to measure non-contact surface temperatures up to 1022F (550C). The differential logger features an LCD display, an 8:1 distance to spot ratio, user selectable resolution and holds 18,000 readings.

Also available with NIST Certificate, and with NIST Certificate but without IR Function.
