The OS91 infrared temperature
scanner is a general purpose
instrument that can measure
surface temperature quickly and
accurately. Because it is
microprocessor powered and
computer calibrated, the OS91 is
highly stable. It has a patented
automatic emissivity compensation
system for close-up measurements;
no emissivity adjustment is required.
The OS91 has a 0.1° resolution that
switches between °C and °F with
the push of a button. Instant lock,
max-reading lock, and min-reading
lock features offer the utmost in
speed and precision. An audible
assist feature beeps when a new
min or max reading is detected.
The OS91 updates its display every
100 ms. The copper-coated housing
shields against EMI/noises, which
makes this model attractive
in the medical field. The one-piece,
high-impact design eliminates
cable and probe failures and
provides unsurpassed durability.
A psychrometer kit (included) allows
measurements of wet and dry bulb
temperatures. The OS91 has a dial
indicator to translate scanned
temperatures into relative humidity
and dew point values.
