Manufacturer: Dwyer Instruments Brand: Dwyer Model: 1235-24-D

Dwyer 1235 series well-tube type manometer uses red gauge fluid, or mercury or green color concentrate to provide direct reading of positive, negative, and differential pressure measurement for determining velocity and static pressures, leakage, fan and blower efficiency, filter resistance, and gas pressures. The manometer is calibrated in inH2O or mmH2O using water and is available in W/M-style for use with fluorescein green concentrate or mercury (sold separately), or D-style for use with red gauge fluid. The water column has 1/10" divisions for inch scales or 2mm for metric units. The scales have a positive mechanism to speed adjustments. Units are silkscreened in black on a white background to ease reading, and sealed with mylar to resist wear. Well assemblies are machined from solid acrylic plastic for durability and are permanently bonded to shatterproof clear plastic tubing to provide leak-proof joints. Visible wells and glands allow operators to inspect the manometer, and overpressure traps prevent fluid loss. The manometer has magnetic clips to mount on vertical surfaces and a clamp bar to prevent slipping. Magnets are removable to customize mounting.SpecificationsPressure typesStatic, vacuum, and differentialMedia typeAir and gasWetted parts materialAcrylic plasticCase materialVinyl tubingScaleInches of water, inches of mercuryFluid typeRed or green gauge fluid, or mercuryConnection1/8"MountMagnetic clipsMaximum pressure100psi, intermittentlyMaximum vacuum5 inHg (10 inHg absolute), intermittentlyMaximum temperature130 degrees FH is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.Manometers measure the pressure of a liquid or gas.

Manufacturer: Dwyer Instruments Brand: Dwyer Model: 477-00-FM

The Dwyer Series 477 intrinsically-safe digital manometer provides positive, negative, and differential pressure measurements, and is used to perform field calibration, monitoring or troubleshooting HVAC systems, performing clean room inspections, air velocity monitoring, and natural gas appliance-line testing. The meter is FM-approved intrinsically safe for Class 1, Div. 1, Group A, B, C, D, T4 hazardous locations. It has an accuracy of + or - 0.5% of full scale at 60 to 78 degrees F, and + or - 1.5% full scale at 32 to 60 and 78 to 104 degrees F. The extruded aluminum case provides durability. The backlit four-digit LCD displays the pressure measurement. User-selectable measurement units include inH2O, mmH2O, bar, mbar, psi, inHg, mmHg, Pa, and kPa. The non-volatile memory function provides storage of up to 40 readings, and audible and visual alarms indicate out-of-range measurements. The zero function nulls minor pressure differences before measuring, and display hold retains last reading when the display cannot be seen during testing. The meter is powered by a 9V battery (included) and automatically shuts off after 20 minutes to preserve battery life.

Manufacturer: Dwyer Instruments Brand: Dwyer Model: 209-AF

Dwyer Durablock Series 250-AF Gages are precision machined 1" thick solid acrylic plastic, virtually unbreakable and free of distortion. The fluid bore is precision drilled to ±.0002" to assure life long accuracy. A glass spirit level is built into the body and encapsulated to prevent damage or tampering. The scale is mirror polished chrome plated brass to assure parallax free reading by alignment of the meniscus with its reflection. Safety traps are incorporated in the body to prevent loss of fluid due to pressure surges. Red and green signal flags indicate clearly when a filter change is necessary. Gages are suitable for use in ambient temperatures of -20 to 150°F. Connection fittings are positively sealed by "O" rings but easily removed for zeroing or addition of fluid. Furnished complete with instructions.

Manufacturer: Dwyer Instruments, Inc. Brand: Dwyer

Dwyer® SERIES 200 & 300 solid plastic stationary gages, or draft gages, are offered in inclined and vertical (well-type) styles for highly accurate laboratory or general industrial service, for measurement of low range gas and air pressures, positive, negative or differential. To assure the accuracy required in instruments of this type, all machining of bores and wells is to the highest standards of precision backed by Dwyer's years of experience in the fabrications of acrylic instruments.
