Detector
Chemiluminescent.
NO + O3 → NO2 + O2 + photon
Cooled Photomultiplier Sensor
Ranges
0-4, 10, 40, 100, 400, 1000, 4000, 10000 ppm plus auto-range
Response time
1.5s (5% to 95%)
Bypass flow sensitivity
Less than 1% from 1 to 3 l/min.
Accuracy and repeatability
Better than ±1% range or ±0.2 ppm which ever is the greater.
Temperature effect
Zero: Less than ±0.5 ppm from 5℃ to 35℃
Span: Less than ± 0.33%/℃
Noise
Less than ±0.5% ppm or ±0.1% of range.
Linearity
±2% of point or ±1% FSD on all ranges down to 10% of range.
NO2 to no converter
95% efficient requiring periodic checking (use Signal NOXGEN tester). Converter Temperature adjustable from the front panel.
Ozoniser
Generates O3 from air with negligible NO production
Air must have less than -12℃ dew point
Converter efficiency
Greater than 95%
Display
240×64 pixel LCD display with back-light shows concentration, units and gas in large clear characters.
Remote control
All functions by 'AK' protocol using RS232 port.
Outputs
0-10 Vdc and isolated 4-20 mA analogue outputs of display range.
Power
Dual voltage 115 Vac or 230 Vac ±15% switchable on the rear panel.
Options
High corrosion resistant dry vacuum pump. Specify mains
voltage required. Pump Control Adaptor. NO2 Measurement.
Environment
5-40℃ ambient temperature.
95% R.H. non-condensing.
Dimensions
19" rack mounting 3U high. (133.5 mm) Depth behind mounting face 590 mm. Protrusion in front of mounting face 45 mm.
Weight approx. 35kg
Services
Air at 520 ml/min with a dew point of less than -12℃
for the ozoniser. NO in N2 diluent for span calibration.
100% N2 for zero calibration.0 psi maximum.
