Gas Composition Independent!

The HVG-2020A vacuum gauge from Teledyne Hastings is a media-isolated, gas composition independent, piezoresistive instrument that provides accurate pressure measurement throughout the rough vacuum region.

The HVG-2020A is easy to install, and the optional display provides the users with several different views, or modes of operation.  The HVG-2020A is very flexible and can provide both analog and digital output to easily integrate into process control. A wide variety of linear analog output signals may be selected.  This makes the HVG-2020A an excellent choice to replace more expensive capacitance manometers.  Digital output can include RS232 and RS485 via a small jack on the top of the instrument.  A USB connection is also available on many models which makes connection and operation very easy.  Free Windows data acquisition software for data logging is available for the HVG-2020A.
