LACO Calibration 1.4E-02 校正棒

A leak standard is a device that, under prescribed
conditions, emits a controlled flow of a specified gas.
This device consists of a leak element (either a physical
orifice or a gas-permeable membrane) that allows gas to pass through to the outlet of the device at a controlled rate.

The rate, called the leak rate, can be accurately quantified by means of calibration.The calibrated leak rate of standards manufactured by LACO will be within the
customer-requested value, plus or minus a manufacturing tolerance.

Several manufacturing tolerances are available. Practical limitations in controlling the variables that contribute to leak rate means that the calibrated leak rate of the
leak standard will normally not exactly match the requested leak rate.
