PALM-SIZED TEMPERATURE/HUMIDITY METER

HN-CH SERIESThe HN-CH series is accurate palm-sized
temperature/humidity meter with the measuring range of
0 to 100%RH by using a high performance and reliable
humidity sensor.
Three types of sensors, sensor built-in type, probe typeand separated type can be selected to meet various
applications requirement.
It also has the data logging function capable to store up
to 8000 readings each of temperature and humidity intomemory, and communications function (RS232C orRS485) for various use such as mobile measurement,
desk-top and wall-mount.
 FEATURES
・Measurement of relative humidity 0 to 100%RH by polymer
capacitance type humidity sensor
・High accurate measurement in low humidity range less than20%RH
・Improved repeatability and reliability by a new developed
humidity sensor
・Design fitted into mobile measurement, desk-top andwall-mount・Logging function of up to 8000 readings each of temperatureand humidity
・Easy maintenance with complete interchangeable sensors
・Three types of sensors, sensor built-in type, probe type andseparaed type meet various applications requirement

 DIMENSIONSDATA LOGGING SOFTWARE (option)●Main body

Unit: mmThe software package records and analyzes the measured data in apalm-sized temperature/humidity meter HN-CH series with the personalcomputer.
It can read the recorded data easily with the spreadsheet software onthe market. RS232C communication type indicates the data list orhistorical trend up to 10 units in the same axis graph easily byconnecting RS232C cable with HN-CH one by one.
And, it has the mode that one measurement data is monitored in realtime.
RS485 communication type connects HN-CH onto the multi-drop-line,
and it can monitor the measured data up to 30 units in real time.

ENVIRONMENT FOR HN-CH・Humidity element is compound from absorbent polymer film and thin element that can transmit vapor.
So under the environment that has the substance mentioned below, the element deteriorates in a short while and measuring fails.
Containing much ketone organic solvent, ester organic solvent, halogen, strong acid substances, corrosive substances, dusts, oil mists, salty mists
・Please do not use HN-CH in where there are explosive gas, corrosive gas and flammable gas or where steam, drug liquid and seawater affect.
It is dangerous to use HN-CH in such environment.
・Measuring is not possible under dew-condensed state, but becomes measurable when returns to a normal state.
