Description

The APOA-370 continuously monitors atmospheric ozone concentrations using a cross flow modulated ultraviolet absorption method. The APOA-370 employs an independent, internal dry-method sampling device to achieve the highest levels of sensitivity and accuracy. The dry method, due to its minimal maintenance requirements and capability of continuously monitoring and instantaneously analyzing gases in their unaltered state, has been a preferred method for monitoring the atmospheric pollution.

Specification

  • Principle: Non dispersive ultra-violet-absorption method (NDUV)
  • Application: O3 in ambient air
  • Range: Standard ranges: 0-0.1/0.2/0.5/1.0 ppm; auto range manual range selectable;can be operated by remote switching.
  • Optional: (measurable) ranges: 4 ranges selectable from 0-10 ppm, within 10 times range ratio; auto range manual range selectable; can be operated by remote switching.
  • Repeatability: ±1.0% of F.S.
  • Linearity: ±1.0% of F.S.
  • Sample gas flow rate: approx. 0.7 L/min
  • Indication: measured value, range, alarm, maintenance screen
  • Alarms: during AIC, zero calibration error, span calibration error, temperature error in ozone separator, light intensity error, etc; on-screen messages are available in four languages - English, German, French, and Japanese.
  • Input/output: • 0-1 V/0-10 V/4-20 mA, to be specified (2 systems: either (1) momentary value and integrated or (2) moving average value)
