PRODUCT FEATURES Description The Thermo-Hygrometer Model CA846 is a portable, compact digital meter designed for simplicity and one-hand operation. The meter uses an NTC as the temperature sensor providing excellent response time to changes in temperature, good repeatability and accurate readings. The Model CA846 also utilizes a thin-lm polymer-capacitive type relative humidity sensor as hygrometer sensor, offering excellent recovery from 100% moisture and fast response time and durability. 1.

Page 10: Operation
Avoid temperature measurement errors induced by too short mea- surement time, sunshine during the measurement, heating, cold outer walls, air draft (e.g. fans), radiating sources including hand and/or body heat, etc. • Avoid humidity measurement errors induced by steam, water splashes, dripping water or condensation on the sensor, etc. • Avoid sensor contamination induced by particles in the air or measure- ments in powder like substances. Contamination may be avoided by measuring through a lter (user supplied). The lter must be cleaned or replaced periodically, depending upon the degree of contamination at the measurement site. Operating the Model CA846 1. Unscrew the protective metal tube covering the sensor. 2. Set the power switch to the desired %RH or °C/°F range. 3. Let the reading(s) stabilize (%RH takes at least 60 seconds to reach 90%). 4. Read the display. 5. After use, screw the protective metal tube back onto the sensor. 6. Turn the instrument OFF when nished. Thermo-Hygrometer Model CA846 1.800.561.8187 information@itm.com www. .com... -
