Portable dew point analyzer - เครื่องวิเคราะห์ dew point แบบพกพา

GEN-25 analyzer is a dew point detection device with micro-controller technology as its core and ultra-thin
alumina capacitive sensor as its measuring unit.It adopts digital processing technology,including zero/range calibration , linearization processing,switch output control,current/voltage output,parameter setting and other funs,all using digital processing technology.The analyzer has the functions of alarm output,communication and analog signal output.

Applications
Manufacturers and users of petroleum,chemical and desiccant,dew point detection of SF6 in power system, measurement of trace moisture in gases of semiconductor manufacturing,drying,food industry,plastic substrate drying,mechanical manufacturing and air separation industries.

Product Features
ㆍThe dew point value,menu,data and working state of the instrument are displayed by 128*64 LCD window, which is intuitive and rich in content
ㆍLong-term stability,high reliability,high accuracy and long calibration cycle
ㆍThe dew point value and volume fraction are displayed simultaneously (ppm/V) to meet the different needs of users.
ㆍBuilt-in large capacity lithium battery,standby time can be more than 48 hours
ㆍMenu Lock-in Switch:Prevent misoperation from changing analyzer's parameters and affecting its normal operation
ㆍ Alarm function:When the dew point deviates from the alarm value,the alarm value can be set arbitrarily within the full range.
ㆍCommunication function:RS485 (standard matching)/ RS232 (optional matching)
ㆍ Isolated analog signal output,0-20mA/4-20mA/0-1V/0-5V/ 0-10V/1-5V analog output mode can be set
