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.
