Zimmerli pressure gauge

PQ) M.F, Zimmer L.D. Lipton, "Dynamic Pressure Measurements on Small Amounts of Detonating Lead Azide", Explosivstoffe 18, 12—15(1970). Abstracted in Expls Pyrots 3(8), 1970. (To evaluate the safery of handling small (few mg to 1 g) amts of LA in daily pilot plant operations, dynamic pressure measurements were taken with/or without protective cloth. The distance from the sample to die gauge was changed from 1 to 30cm)... 

The three most common methods for measuring pressure in systems in the region of O.I torr (0.013 kPa) or above are the U-tube manometer, and the Zimmerli and McLeod gauges. Digital gauges are becoming available.
