Type K/J Dual Input Thermometer
Dual Inputs and Side-Button Controls
For calculation of differential temperature readings while side buttons allow for
convenient one-hand operation
• Large backlit LCD displays T1, T2, T1-T2
differential, plus Min, Max, and Avg
• Wide temperature range with 0.1°/1° resolution
• Readout in °F, °C, or K (Kelvin)
• Data Hold function freezes reading on display
• Max/Min/Avg readings with relative time stamp
• Offset key used for zero function to make
relative measurements
• Auto Power off with disable feature
• Complete with two general purpose Type K
bead wire temperature probes, three AAA
batteries, and pouch case
Optional Accessories:
