Vacuum Instruments Corporation (VIC) offers a high-quality line of calibrated gas leaks traceable to National Institute of Standards Technology (NIST). Calibrated gas leaks are used to provide a controlled delivery of gases at a relatively low flow rate. Most leaks are available to ship within one week upon order, but many configurations are stocked and ready to ship.
The OM Series gas calibrator leaks utilize a precision tapered glass capillary as the leak element. Gases pass through a single orifice, with the leak rate dependent upon size and gas pressure. To prevent clogging of the fine orifice, a unique particle trap is located between the capillary tube and outlet fitting.
The PM Series – Helium based – Gas Permeation Leak Calibrators utilize a durable 7740 Pyrex glass permeation leak element which permits diffusion of helium gas.
Ideal for calibrating VIC’s TurboTest™MD-490S and halogen sniffing instruments. These leaks are specifically designed for atmospheric sniffing applications.
