Detector
Dual chamber gas filled variable capacitor utilising RF detection to optimise sensitivity
Reages
Dependant on gas, from ppm up to 100% concentration
Response
Typically less than 15 seconds (5-95%) at 1 l/min flow with time constant of 2 seconds
Bypass Flow Sensitivity
Typically less than ±1% change in reading from 0.2 to 2.0 l/min into ambient pressure exhaust.
Accuracy & Repeatability
Better than ±1% of range or ±0.2ppm, whichever is greater.
Linearity
Better than ±0.5% of range
Ambient Temperature Effects
Zero: ±0.2% per ℃ of highest range from 5℃ to 30℃
Span: Less than ±0.2% of range from 5℃ to 30℃
Chart recorder output: add ±0.02% of range per ℃
±15%. 50Hz and 60Hz compatible.
Max power consumption 200 VA.
Drift
Zero and span drift are less than 1% of range in hour at constant temperature and pressure.
Display
240×64 pixel LCD display with switchable back-light shows concentration units and gas in large, clear characters.
Outputs
Non isolated 0-10Vdc, isolated 4-20mA analogue outputs of displayed range,
Range analogue output is supplied.
Remote control
Serial interface RS232 using AK protocol all functions available.
Logic control Full function control via digital inputs, status monitor via digital outputs.
Autocalibration
Controlled by microprocessor, RS232 or switched logic.
Sample condition
Gas to be analysed must not exceed 50℃, with a dew point of 10℃ below local ambient temperature.
Safety
All high voltage/current circuits are shielded within the analyser.
Dimensions
19" Rack or bench mount 4U high. 550mm behind mounting face, 45mm in front of mounting face.
Approximate weight
18kg
Power
Switchable between 115V and 230V AC ±15%.
