Dwyer Mark II M-700PA红油差压计，文章来源于Dwyer，Dwyer Mark II M-700PA 模压塑料压力计的量程为10-0-700 Pa，红油，.829 sp. gr。Dwyer Mark II系列模压压力计有倾斜和倾斜垂直两种类型。25型真空计的弯曲倾斜垂直管提供更高的量程，在低读数下更容易读取增量。Model 25 非常适合通用工作。40 型斜规在整个范围内提供线性校准和出色的分辨率。40型非常适合风速和空气过滤器压力表应用。两种压力表类型都能够进行高于和低于大气压的压力测量以及压差测量。德威尔压差表M-700Pa  M-700PA，是一种超低量程、廉价、结构牢固的现场指示仪表。M-700PA红油压差表是DWYER的主流产品，M-700PA红油压差表是利用无摩擦的magnehelic运动原理，消除了磨损和间隙。DWYER  M-700PA红油压差表里无留液，不会汽化和冻结，M-700PA红油压差表可以迅速指示低压、非腐蚀气体的压力。Dwyer Mark II M-700PA Red Oil Differential Pressure Gauge, article from Dwyer, Dwyer Mark II M-700PA Molded Plastic Pressure Gauge has a range of 10-0-700 Pa, red oil, .829 sp. gr. The Dwyer Mark II series of molded pressure gauges are available in tilted and tilted vertical versions.The curved tilt of the Model 25 vacuum gauge Vertical tubes provide higher range and easier incremental readings at low readings.The Model 25 is well suited for general purpose work.The Model 40 Inclined Gauge provides linear calibration and excellent resolution over the entire range.The Model 40 is well suited for anemometry and air filter gauge applications.The Model 25 has an inclined vertical tube that provides a higher range and easier incremental readings at low readings.The Model 25 is well suited for general purpose work. Both gauge types are capable of above and below atmospheric pressure measurements as well as differential pressure measurements. DWYER Differential Pressure Gauge M-700Pa The M-700PA, is an ultra-low range, inexpensive, solidly constructed field indicator gauge.The M-700PA Red Oil Differential Pressure Gauge is a staple of DWYER's lineup.The M-700PA red oil differential pressure gauge is designed to utilize the principle of frictionless magnehelic motion, eliminating wear and gaps.The M-700PA red oil differential pressure gauge in DWYER's M-700PA red oil differential pressure gauge is designed to be used in a variety of applications. With no residual liquid to vaporize or freeze, the M-700PA Red Oil Differential Pressure Gauge can quickly indicate the pressure of low-pressure, non-corrosive gases.

结构：Mark II压力计价格经济、结构紧凑，而且有固定式和便式两种构造可以提供。40型标准配有便携式支架。25型可以选图A-612支架。它的结构简单，由牢固的白色模制聚苯乙烯外壳、指示管和流体套管、模制ABS调节钮、零点调节活塞、防震水平仪和防漏的”0"形密封环组成。25型所带的溢流罐可以缓解适度过压。40型的过压保护是通过浮动的活门来实现的。刻度刻在铝壳和环氧涂层上。CONSTRUCTION: The Mark II manometer is economical, compact, and available in both stationary and portable configurations. model 40 comes standard with a portable stand. model 25 is available with the optional A-612 stand. Its simple construction consists of a solid white molded polystyrene housing, indicator tube and fluid sleeve, molded ABS adjusting knob, zero adjusting piston, shock level, and leak-proof "0" sealing ring.The Model 25 comes with an overflow tank to relieve moderate overpressure.The Model 40's overpressure protection is provided by a floating flapper. The scale is engraved on the aluminum case and epoxy coated.
安装：Mark II压力计使用两个可装在何垂直的表面上。在安之前，使用内置的水平仪就可进行校准。只要将储液处加满，将液体刻度调整至零，再接上软管，压力计就可以开始使用了。INSTALLATION: The Mark II manometer uses two vertical surfaces that can be mounted on the HO. Calibration can be done using the built-in level prior to installation. Simply fill the reservoir, adjust the fluid scale to zero, and connect the hose, and the manometer is ready for use.
