Dual-laser targeting indicates the ideal measuring distance to ensure accuracy
Fast 0.15-second response time
Rugged, double-molded housing
These infrared thermometers features dual lasers that converge to a 1" target spot to ensure accurate targeting and temperature measurement. All thermometers feature a backlit dual display for clear and easy reading. You can program the adjustable high/low setpoints with audible alarm to alert you when set point temperature is exceeded. Adjustable emissivity for increased measurement accuracy on virtually any surface color, finish, or texture. Other features include Fahrenheit or Celsius selectable units, current and maximum readings, auto hold, continuous scanning, and auto power off.
.Color alert model 90440-84 features a blue backlit dual display that changes and flashes to a red backlit display when the temperature reading exceeds the high or low set points. The display will continue to flash red until normal temperature is reached.
What's Included:
one 9 V battery and storage pouch.
