Model 301
type-2 sensor |
The Model 3 01 combines state of the art microprocessor technology with the solid reliability of Digital Control Systems' industrial products to make this full-featured air quality monitoring subsystem less complex and more robust than previous generations of instrumentation. It is so reliable we back it up with an unprecedented two year warranty: twice the industry standard.
Advanced design provides a highly stable, drift-free output requiring less-frequent calibration. Voltage and current outputs make the Model 301 easy to interface with most advanced HVAC facility management systems. The optional contact closure output can directly control the system's fresh air damper to maintain C02 levels within preset limits.
The Model 301with Type-2 sensor is designed for demanding industrial and commercial applications that require reliable performance. With its broad range of input voltages, low power consumption and sturdy metal enclosures for either wall or duct mounting, this flexible monitor is easily incorporated into a broad range of applications.
The simple one-point calibration procedure makes the Model 301 easy to maintain in the field. An optional digital readout showing C02 concentration in parts per million is also available.
