Time to Reading Initial reading 10s after exposure, final
reading 20s after exposure
Initial reading 20s after exposure,
final reading 40s after exposure
Initial reading 30s after exposure,
final reading 70s after exposure
Temperature Compensation Temperature compensated to give accurate readings independent of starting probe temperature
Maximum Permitted Probe Temperature 70°C before measurement, 140°C after measurement
Display 2x8 character LCD. Character height 5mm. CE Approved.
Operation Mode AUTO: Automatic measurement with laser set to 10s timed exposure. Unit senses temperature rise ａnd measures automatically.
MANUAL: User places probe in front of beam for 10s. Unit beeps to indicate start ａnd stop measurement points.
History: Stores last three readings. Calibration: Can be recalibrated by user.
Battery 2 x AA. Lifetime in normal use
approximately 1 year.
