Control Unit, Power Supply, Batteries and Charger

Control Unit 3000-C

Design: Aluminum housing featuring integrated PC module, large graphical LC-display with touch screen, 4-channel CO2/H2O gas analyzer, flow control, CO2 control (supplied via small cartridges or cylinders) and H2O control (for drying and humidifying). Pneumatic connectors for air inlet, measuring head and four vents. Sockets for cable connections with Measuring Head 3010-S, PC (USB interface), two auxiliaries, two Li-ion Batteries 3025-A (or AC Power Supply 3020-N or external DC) and one additional component

CO2/H2O Gas Analyzer

Design: 4-channel CO2/H2O absolute NDIR gas analyzer, separate cuvettes for CO2 and H2O

CO2 measurement: Simultaneous absolute and differential measurements, absolute range: 0 to 3000 ppm, cuvette length 20 cm, cuvette volume of one cell 6 cm3, gas-filled detector

H2O measurement: Simultaneous absolute and differential measurements, absolute range: 0 to 75000 ppm, cuvette length 20 cm, cuvette volume of one cell 6 cm3, pyroelectric detector (solid state)

Max. noise in absolute mode: <0.2 ppm CO2 and <30 ppm H2O

Resolution: 0.01 ppm CO2, 1 ppm H2O

Linearization:
CO2 absolute: Max. error between 0 and 600 ppm: 12 ppm, above 600 ppm: 2% of measured value
Deviation of differential CO2 zero with changing CO2: Typ. less than 0.5 ppm
H2O absolute: Max. error between 0 and 15000 ppm: 330 ppm, above 15000 ppm: 2% of measured value
Deviation of differential H2O zero with changing H2O: Typ. less than 150 ppm

Correction: Signal is corrected for temperature, pressure and H2O-effect on CO2 signal
