دستگاه مانیتورینگ چهار کاناله گاز H2S برند MSA مدل ۲۲۸۰A
(MSA Brand Four Channel H2S Gas monitor Model 2280A)
Description
The Model 2280A is a four-channel system specifically designed for continuous monitoring of Hydrogen Sulfide (H2S) gas in the ppm (parts-per-million) range.
The 2280A controller is a microprocessor-based instrument, which features recent advancements in electronic circuitry and packaging techniques.
The system consists of four remote sensing assemblies and a solid-state controller.
The controller consists of four independent channels, each having its own control circuitry.
The sensors are monitored independently (i.e. they are not scanned, nor are the signals summed).
User interfaces are provided so that the operator may interpret and direct the Model 2280A in the performance of its various functions.
User interfaces consist of a digital display, status indicators, a mode button and a reset button.
The digital display provides the user with the gas concentration at the sensor site, fault diagnostic
codes, calibration prompts and setup parameters.
The controller should be mounted in a weather protected non-hazardous area.
Several General Monitors accessories are available for panel, wall or 19- inch rack installation.
For hazardous areas an explosion proof housing is available for Class I, Division 1, Groups C and D.
