Dwyer Capsuhelic® 4000 Series Differential Pressure Gauge

Use Dwyer Capsuhelic gauges for fast, accurate indication of differential pressures, when measuring flowing fluids, pressure drop across filters, liquid levels in storage tanks and other applications involving pressure, vacuum or differential pressure. With ranges from 0" to 5" WC to 0' to 35' WC, the Capsuhelic works with system pressures of up to 500 PSIG, even when differentials are less than 0.1" WC.
