PREPARATION
Ensure that the sensor is positioned so that it is focused on the target only.
OPTICS

larger spot. The measurement accuracy is
not affected by the measurement distance.
There is no maximum measurement
distance provided the air between the
sensor and target is free of obstructions.

Avoid thermal shock. Allow 20 minutes for the unit to adjust to large changes in ambient
temperature.

Smoke, fumes or dust can contaminate the lens and cause errors in temperature
measurement. In these types of environment, the air purge collar should be used to help keep
the lens clean.
