The DGM-SK25R Secondary Reference Meter is designed for calibration of EPA Method 5, Method 6, and mercury source sampling consoles. The unit is fitted with an optical encoder and digital display.

The reference meter connects to the console via an integrated hose which includes a thermocouple for monitoring temperature. Vacuum is controlled by means of a panel-mounted ball valve. All components are contained in an easy to carry transport case.
