Description

SENTRY Infrared Thermometer - ST643

eSmart, Audio alarm, Laser Sight Switchable, Auto-measuring

 

An intelligent non-contact infrared thermometer from Sentry is the ST643. Two innovative functionalities are integrated in addition to the standard temperature measurement devices.
Users can measure the target temperature with the e-Smart feature without knowing or checking the material's emissivity, which is very advantageous (properties of the surface).
Additionally, the user is informed when the temperature exceeds the selected alarm temperature by the clear color signals.

As a quick report, ST643 from SENTRY comes with the following features:

  • Rugged and Ergonomic Design
  • DS ratio 12:1
  • Temperature Range -32~760℃ (-25.6~1,400℉)
  • Resolution 0.1℃ (0.1℉)
  • E-smart: Emissivity automatic measurement
  • CIS: Noticeable color signs alert when the temperature over the setting poin
