Dwyer 209 压力表，倾斜固定

这些固体塑料稳固风压表适用于高度精确的实验室或一般工业服务，低量程气体和空气的压力，正压，负压或差分测量。每个仪表都配有备用压力表油和快速切断型，成型尼龙管接头，两个3'长度软管和2-1/8“管螺纹适配器。

特点

1“厚的丙烯酸塑料机身的固体块，几乎是牢不可破的，稳定的和绝对无变形危险 

3/16“孔，精确到±.0002”永久无弯曲，因为扭曲，不需要重新校准，

磨砂玻璃气泡水平仪对115/125Sec/mm 敏感。是1/2“长×375”直径，并提供有两个红色的线，便于可视和对齐 

无扭曲读数最大精度一致性通过简单校准半月板反映在抛光铝的刻度

选择压力表油以及润湿性高的特点，形成了一个一致的弯月形完美的可读性 

O型圈密封液位柱塞调节，方便归零 

These solid plastic stationary draft gauges are for highly accurate laboratory or general industrial service, for measurement of low range gas and air pressures, positive, negative or differential. Each gauge is furnished with spare gauge oil and rapid shut-off type, molded nylon tubing connectors, two 3' lengths of flexible tubing and 2-1/8" pipe thread adapters.

FEATURES

1" thick acrylic plastic body is a solid block, virtually unbreakable, stable and absolutely free of the danger of distortion 

3/16" bores, accurate to ±.0002" are permanently free of bends or crooks, will not require recalibration because of distortion 

Ground glass bubble level sensitive to 115/125 Sec/mm is 1/2" long x .375" diameter and provided with two red lines for easy visibility and alignment 

Parallax-free reading for maximum accuracy and consistency is achieved by simply aligning the meniscus with its image reflected in the polished aluminum scale 

Selected gauge oil with high wettability characteristics forms a consistent well shaped meniscus for perfect readability 

O-ring sealed fluid level plunger adjustment for easy zeroing
