Model 630

K-type Thermocouple Compact

Digital Thermometer

The 630 is a portable 3 1/2 digit, compact-sized dual input dig-

ital thermometer designed to use external K-type thermocouples

as temperature sensors. This unit can display the temperature

difference between it two inputs.

Model 635

Compact Digital Infrared Thermometer

The 635 is a portable easy to use 3 digit, compact sized

infrared digital thermometer with laser pointer, designed for sim-

ple one hand operation. Meter comes with Backlit LCD display,

Auto-hold function and auto power down (20 seconds approx.)

after releasing MEAS button to extend battery life.

Model 625

Compact Digital Thermo-Hygro Meter

The 625 is a portable 3 1/2 digit, compact-sized digital

Thermo-Hygrometer designed for simplicity and one hand opera-

tion. It can measure and display an environment temperature and

humidity in a fraction of a second.
