 ST-8891/8891A/8891B/8891C/8891D/8891E Professional Thermocouple Thermometers

ST-8891/8891A/8891B/8891C/8891D/8891E contact thermometers offer fast response and laboratory accuracy. These thermometers work with K-type thermocouples and one IR temperature probe as temperature sensors, and offer 0.1℃/0.1℉ resolution.

 Large backlit display shows any combination of T1,T2,T3,T1-T2,T1-T3,T 2-T3 plus MAX,MIN,AVG

 Relative time clock on MAX, MIN, and AVG provides a time reference for major events

 Electronic Offset function allows compensation of thermocouple errors to maxi-mize overall accuracy

 Readout in ℃,℉, or Kelvin(K)

 USB interface, USB to UART Bridge Controller( 8891C/8891D/8891E)

 18,000 records data logger per channel (8891C/8891E)

 Auto power off mode (sleep mode) energy saver
