PALM-SIZED TEMPERATURE/HUMIDITY METER
Portable temperature/humidity meter: HN-CH - 14570 HN-CH SERIES
The 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 type and 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 into memory, and communications function (RS232C or RS485) for various use such as mobile measurement, desk-to p 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 than 20%RH
Separated type
Improved repeatability and reliability by a new developed humidity sensor Design fitted into mobile measurement, desk-top and wall-mount Logging function of up to 8000 readings each of temperature and humidity
Probe type
Easy maintenance with complete interchangeable sensors Three types of sensors, sensor built-in type, probe type and separaed type meet various applications requirement
