Visual Indicator Housing with CO & Moisture Elements

Visual indicator housing with 1/4 in FNPT inlet and outlet. Supplied with carbon monoxide (CO) and moisture (H2O) elements.


Visual indicators warn compressor operators of an impending need to change filter cartridge(s). At the core of this unit are elements. Elements contain reagents which respond to a specific contaminant within a determined range. The elements in SKU 592-6 are included with this visual indicator and detect the presence of carbon monoxide (CO) and moisture (H2O).

Since the indicator's element “sees” the gas at actual operating pressure and conditions, it is fairly accurate and is very helpful in determining cartridge lifespan. However, it does not take the place of scientific instruments nor give quantitative measurements.
