Dwyer 1211-12 卷起U型管压力计

实验室精确测量方便卷起压力计

尼龙成设计几乎是牢不可破

这些松管压力表同实验室最好的“U”型仪表一样精确，但他们可以卷起，方便携带，并以承受野蛮使用.简单展开松管压力计并设置了读取静压，真空，或压差。磁性夹紧紧夹住任何钢材表面，或把它挂在钉子上。打开连接器。施加压力时，加的英寸数的一列行进的英寸数的其他列沿着。当读取完成后，关闭连接器密封，卷起压力计成小巧型线圈，并在其圆形的金属外壳或工具盒将它保存起来。没有流体损失。无松帽或插入损失。

松管压力表覆盖广泛的压力读数0到4“到60到0到60”。使用他们确定速度静压，泄漏，风扇或鼓风机的测试，校准控制装置，检查气体压力和许多其他应用。

A handy roll-up manometer with laboratory accuracy

Molded, all-nylon construction is virtually unbreakable

These Slack Tube Manometers are as accurate as the finest laboratory “U” Gauges, yet they are made to roll up compactly for easy carrying and to withstand rough usage.Simply unroll the Slack Tube Manometer and set up to read static pressure, vacuum, or differential pressure. Magnetic clips hold it firmly to any steel surface or hang it on a nail. Turn connectors one revolution to open. When the pressure is imposed, add the number of inches one column travels up to the number of inches the other column travels down. When reading is completed, turn connectors to seal columns, roll up manometer into compact coil and tuck it away in its circular metal case or tool box. No fluid loss. No loose caps or inserts to lose.

Slack Tube Manometers cover a wide range of pressure readings from 4 to 0 to 4" up to 60 to 0 to 60". Use them in determining velocity in static pressures, for leakage, fan and blower tests, calibrating control devices, checking gas pressure and many other applications.
