*Response time for temperature and humidity is highly dependant
on the air flow over the exposed sensors. With air flow,
response time is within a few minutes to adjust to the ambient
temperature and relative humidity. With no air flow, several
minutes may be required to adjust properly.
Operating Temperature:
Normal operating temperature: -10°C to +70 °C (14°F to 158°F)
Reading of display still possible: -20°C to -10°C (-4°F to 14°F)
Slow reading of display, but instrument still working: -40°C to
-20°C (-40°F to -4°F)
Power:
Instrument: 1 button lithium batteries 3V CR2032
LED Light:1 button lithium batteries 3V CR2032
INCLUDED: 4 button lithium batteries 3V CR2032 (1 spare for
instrument, 1 spare for LED light)
Dimensions:
46 x 120 x 32 mm - 1.81 x 4.73 x 1.26 in
171 grams - 6 oz.
Impeller: diameter 17.8mm (replaceable)
Waterproof 5 minutes at 1 meter. Allow for the humidity
sensor to be well dried out before using again.
