Gauge Fluids -- 3/4 ounce sizes are furnished in unbreakable plastic dispenser type bottles. Larger sizes are supplied in plastic bottles with screw caps. Mercury is supplied only in the single size plastic container. CAUTION: Use only Dwyer fluids in Dwyer gauges.

Gauge Tubing -- Clear plastic tubing is easily inspected and is therefore best for test applications where a possibility of fluid entering the tubing exists. Rubber tubing has less tendency to kink in storage and occupies less space, thus is best for portable work. Metal tubing is recommended for permanent installations. Double column tubing is used with Mark II Manometers and the Wind Speed Indicator.

Static Pressure Sensors -- These sensors are for use the Manometers, Magnehelic® Gauges, Pressure Switches and other controllers to pick up or sense static pressure drop across air filters and cooling coils, blower input and discharge pressures, etc.

Valves/Connectors -- Instrument valves for permanent installation. They can connect to metal tubing or 1/8" pipe. Connectors are replacements for all Dwyer Manometers. They are interchangeable for added flexibility in applications.

Fittings/Filters -- A wide variety of fittings for use with most Dwyer products. Special line filters for the Magnehelic® Gauge and Capsuhelic® Gauge allow use with dusty environments. Particulate filters are used for Dwyer Flowmeters to keep the air clean.

Pumps -- Used as pressure source in calibration and leakage tests.

Carrying Cases -- Steel cases are substantially constructed and finished in gray hammerloid. Molded plastic cases are gray, high density polyethylene.

Thermometers -- Pocket sized for simple testing.

Psychrometers -- Used for handheld, non-electric humidity metering.

Slide Charts -- Air Velocity calculator slide chart makes spot checking with Dwyer Pitot Tubes quick and easy.

Miscellaneous -- Various mounting options for Dwyer products. Brackets and magnet assemblies are just a couple of examples.

Accessory Kits for Air Filter Switches -- Use with differential pressure gauges or switches to measure the resistance of air flow through filters.

Technical Reference Books -- Dwyer is now selling technical reference books that we feel will be a great tool for our customers. We are now offering HVAC Engineer's Handbook by Fred Porgies; Plant Engineer's Handbook by Keith Mobley; and Instrumentation Reference Book by Walt Boyles.
