Ventilation monitor

The Dietz Model 190 from The Henry G. Dietz, Co, Inc. is a precision manometer available in differential pressure ranges down to 0.5-in. W.C., with a resolution of 0.001-in W.C. It has an accuracy of 0.5 percent, repeatability, low hysteresis, and accurate operation over a broad temperature range, and is highly insensitive to vibration.

It is provided with a digital readout of the pressure and can function as a switch to actuate an alarm, if there is air failure, by using an internal alarm system or a DPDT relay contact rating.

It can also determine if there is an appropriate air supply, low air velocities, and low differential pressure to determine ventilation of cleanrooms.

The Model 190 includes maintenance-free performance and operating life within specifications after 10 million cycles.
