This instrument is a portable 3½ digit, compact-sized digital Thermo-Hygrom-
eter designed for simple one hand operation. Uses Platinum Resistance Tem-
perature Detector Pt385/1000W (Alpha=0.00385) as temperature sensor, and
uses thin film polymer capacitive type relative humidity sensor as hygrometer
sensor.
It is recommended that you read the safety and operation instructions before
using the hygrometer.
• Do not immerse the hygrometer sensor head into liquids since this
causes permanent damage to the sensor.
• The meter when not in use, please use protective metal cap cover the
sensor head and rotate clockwise it to extend sensors life.
The
symbol on the instrument indicates that the operator must refer to an
explanation in this manual.
