Ambient Sulfur Dioxide Monitor
The APSA-370 is a device for the continuous monitoring of atmospheric SO2 using 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.
