Detailed Description:
This dew point meter which adopts imported film capacitive humidity sensor and micro computer technology is developed as an intelligent trace moisture measuring instrument with good performance. Its operation is simple and it has the function of conversion among Td, RH, PPM and software upgrade. It can measure the content of trace moisture in various gases.
Application
It is applied in the industries such as petroleum, chemical, cement, metallurgy, iron and steel, desiccant manufacturers and users, semiconductor manufacturing, drying industry, food industry, plastic substrate drying, machinery manufacturing, air separation and other industries to detect the trace moisture content of various gases.
Features
u Imported high performance built-in full compensation film capacitor dew-point sensor (Finland VISALA)
u Zero point and slope self-calibration after start, dew point calibration by single point way for full range (patent technology)
u Sensor dry protection device (patent technology)
u Unique gas circuit design, good gas tightness and permeability, water resistance.
u Large screen TFT liquid crystal displays dew point value and the corresponding RH % relative humidity value, PPM moisture value
u Color touch screen control, Chinese/English operation menu
u Measurement data storage and query
u Intelligent power prompt, intelligent charging protection
u Lithium battery offers power supply long standby
Technical Parameters
Measurement of dew point:-80~+20°C
When the dew point temperature is lower than 0°C,
the output of sensor is frost point
Typical precision: higher than±2°C
Response time (Td):
When the gas temperature is 20°C:
-60→-20°C 5s (63%),10s (90%)
-20→-60°C 45s(63%),10min(90%)
Operation environment:
Temperature -20~+60°C
Relative humidity 0~100%RH(non condensation)
