1. INTRODUCTION

The one input contact thermometers offer fast response and laboratory 
accuracy. These thermometers work with K-type or J-type thermocouples 
as temperature sensors, and it has 0.1°C/0.1°F resolution.

3. FEATURES

1.  Large backlit display shows any combination of T1, plus MAX, MIN, 

AVG.

2.  Relative time clock on MAX MIN and AVG provides a time reference for 

major events.

3.  Electronic Offset function allows compensation of thermocouple errors 

to maximize overall accuracy.

4.  Work with tow K-type or J-type thermocouples as temperature sensors.
5.  Readout in °C, °F or Kelvin (K).
6.  Auto Power Off mode (Sleep mode) increases battery life.
