Dwyer Instruments 3000MR-00 Photohelic Differential Pressure Switch/Gauge 0-0.25" WC

The Dwyer Instruments 3000MR-00 Photohelic Differential Pressure Switch/Gauge is a monitoring system, that measures differential air pressure while providing switching capability for compatible equipment. It is used to observe pressure changes and activate connected controls when selected limits are reached. Designed with a 00.25" water column (WC) operating range, it is suitable for low-pressure applications involving air movement and filtration. In commercial and industrial facilities, HVAC systems use this instrument to monitor airflow conditions and allowing them to maintain proper equipment operation, accurate pressure control and consistent performance during regular service.
