Thermal Conductivity Gas Analyzer   Overview Easy-to-see large LCD is helpful for efficient operation. Measured value output signals are linearizable (at option). Line voltage lies within 100 V to 240 VAC, 50/60 Hz. Zero point and span can be automatically calibrated (at option). Other gases interference is correctable (at option). Commuticable with other system through an RS-232C interface (MODBUS™)(at option).       Technical Specification     ● Measuring principle: Meaturement of thermal conductivity ● Measurement component: He, Ar, H2, CH4, CO2 ● Measurement range: Refer to Table 1 ● Repeatability: ±1%FS ● Drift: Within ±2% of full scale/week ● Response time(90% response) : High speed type within 10 sec Standard type within 60 sec ● Output signal: 4 to 20mA DC or 0 to 1V DC, 0 to 10 mV DC ● Display unit: LCD with backlight ● Mounting: Flush mounting on panel ● Power supply: 100 to 240V AC, 50/60 Hz ● Optional specifications: Linearization Relay contact output Contact input Interference gas meatured value input Automatic calibration function Communicating function
