APSA-370 Ambient Sulfur Dioxide Monitor/analyser

Category: Tags: , ,

The APSA-370 is a device for the continuous monitoring of atmospheric SOusing UV fluorescence.

The APSA-370 employs an proprietary, internal dry-method sampling device to achieve the highest levels of sensitivity and accuracy. The dry-method, due to its minimal maintenance requirements capability of continuous monitoring and instantaneous analysis of gas in its unaltered state, has been a preferred method for monitoring the atmospheric pollution.

Features:

• UV-fluorescent detector resistant to moisture interference; Low range: 0-0.05 ppm F.S.
• Alternately to FDP measurements, the detector design is highly SO2 selective and requires no supplemental gas.
• Integral HC-cutter with a selective membrane eliminates interfering components.
• Incorporates a lamp intensity compensator.
• Uses a built-in inert PTFE sample inlet filter.
