Detector
Non dispersive infra-red gas correlation rotary filter system
with solid state detector.
Response
Typically less than 15 seconds (5-95%) at 1 l/min flow, with time constant of 2 seconds
Bypass Flow sensitivity
Less than ±1% change in reading from 0.2 to 2.0 I/min into ambient pressure exhaust.
Accuracy & Repeatability
Better than ±1% of range or +/- 0.2 ppm, 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 ±0.35% of range from 5℃ to 30℃
Chart recorder output: add ±0.02% of range per ℃
Drift
Zero and span drift are less than 1% of range in 1 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 inerface using RS232. All functions by 'AK' protocol with variable baud rate between 1200 and 19200.
Autocalibration
Controlled by microprocessor, RS232 or switched logic.
Sample condition
Gas to be analysed must not exceed 40℃, 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 3U high. 550mm behind mounting face, 45 mm in front of mounting face.
Services
Sample, span and zero inlets -1/4" tube fittings, bypass outlet 3/8". Zero grade N2 for zero calibration and dual cell purge. Span calibration gas.
Approximate weight
13kg
Power
Switchable between 115V and 230V AC ± 15%, 50Hz and 60Hz compatible. Max power consumption 200 VA(warm up). |
