Mark II Molded Plastic gauge 
 3% accuracy, for a fixed location and portable applications, cheap 
 Dwyer Mark II series molded manometers and inclined sub-inclined - vertical. 25-type pressure gauge curved tilt - a large vertical tube can provide range, and when the increment in the low reading is more obvious, easy reading. 25 pressure gauge is particularly suitable for general purpose applications. 40 inclined manometer in the range available within the linear calibration and excellent resolution. 40 pressure gauge is especially suitable for measuring wind speed and air filter applications. Both types of gauges can measure the pressure (gauge pressure), negative pressure (gauge pressure), and differential pressure. 
 Construction - Mark II manometers affordable, compact, and both fixed and portable structures available. The standard type with a portable stand 40. 25 type can be equipped with A-612 bracket. This anemometer is very simple structure, molded by the strong white polystyrene shell, indicating tube and fluid tube, molded ABS controls, zero adjustment piston, the glass scale with shock absorber tubes, and leak-proof "O" ring seal ring. Type carried by the overflow tank 25 to relieve moderate overvoltage. 40 carried by the float-type over-voltage protection device can be manipulated to provide greater protection. Aluminum and epoxy coating on the scale lithography. 
 Installation - Mark II manometers can be fitted with two screws provided on any vertical surface. Built-in water level in the mounting screws before tightening the standard of measurement can be simplified. Simply fill the reservoir at will be adjusted to zero liquid scale, connect tubing tube manometer can start to use. 
 Accessories - each with two Mark II pressure gauge with 1 / 8 "sheet metal pipe or tubing to match the square pipe fittings, two mounting screws, 3 / 4 ounce bottle of indicator solution, marked in red and green pointers, and complete instructions. 25 type also has 8 feet of flexible plastic tubing tube double row. using A-612 can support 25 types of portable portable operation. 25 type pressure connector tubing can tap a short tube, used to accommodate the measurement of oil through. 40 type with two 41 / 2 feet long plastic tubing pipe, and portable plastic bracket and standard screws out. It also closed with a compression fitting to facilitate the rapid and integral over-voltage protection device . 
 OEM features - all of Dwyer Mark II Molded plastic manometer can add your name or special graphics requirements and scale to provide you with OEM quantity. 
 Dwyer Mark II for HVAC and clean room, surveying the room before and after the pressure and filter.
