Dwyer 1211-12 卷起U型管壓力計

Dwyer 1211-12 卷起U型管壓力計

實驗室精確測量方便卷起壓力計

尼龍成設計幾乎是牢不可破

這些松管壓力表同實驗室最好的“U”型儀表一樣精確，但他們可以卷起，方便攜帶，并以承受野蠻使用.簡單展開松管壓力計并設置了讀取靜壓，真空，或壓差。磁性夾緊緊夾住任何鋼材表面，或把它掛在釘子上。打開連接器。施加壓力時，加的英寸數的一列行進的英寸數的其他列沿著。當讀取完成后，關閉連接器密封，卷起壓力計成小巧型線圈，并在其圓形的金屬外殼或工具盒將它保存起來。沒有流體損失。無松帽或插入損失。

松管壓力表覆蓋廣泛的壓力讀數0到4“到60到0到60”。使用他們確定速度靜壓，泄漏，風扇或鼓風機的測試，校準控制裝置，檢查氣體壓力和許多其他應用。

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.
