42509 IR Thermometer

with Color Alert

Extech’s 42509 is one of the fastest and most
accurate IR Thermometers with dual lasers
identifying the distance and location where
accuracy is highest. Fast response is ideal for
quick checks of multiple spots in a process
or for catching spikes in temperature. Easy
programmable High/Low Alarm with fast two

Blue backlight:

within temperature

range

Red backlight plus

audible alert: exceeds

temperature

Features

• Great for processes that require temperature control

and monitoring

• Fast and accurate measurements at 12" (30cm) where

the two lasers converge with 12:1 field of view

• Programmable alarm with audible beeper — Blue

backlit dual LCD display changes to Red backlit when

reading exceeds High or Low set points

• Exclusive 150 millisecond instantaneous response for

capturing spikes in temperature

• Max Hold

color display and audible alarm.

• Lock function for continuous readings

• Adjustable emissivity increases measurement accuracy

for different surfaces

• Double molded housing
