About Teledyne Hastings Instruments
Founded in 1944 as Hastings Instrument Company by Charles and Mary Hastings, the company boasts a long history of success. The late 1940s saw the introduction of thermocouple (TC) technology. This technology was the foundation for many early Hastings-produced instruments such as air velocity indicators, thermal mass flow meters, stack emission monitors, and, of course, the thermopile vacuum sensor. By 1964, Hastings Instruments had grown into one of the leading vacuum and thermal mass flow companies in America and in 1968 became part of Teledyne Incorporated.
Teledyne Hastings Instruments is a trusted manufacturer of a wide range of quality Vacuum Instruments and Gas Mass Flow Instruments. Our vacuum product line includes the original DV-4 and DV-6 thermocouple gauge tubes, along with other vacuum sensors used in combination with meters and controllers that cover a wide range of vacuum pressure from atmosphere to ultra-high vacuum. The gas mass flow line of meters and controllers covers a broad range of flow rates from 5 sccm to 15,000 slm that includes a variety of flexible options for outputs, calibration, and fittings.

The Teledyne Hastings’ DV-5 series thermocouple vacuum gauge tube/sensor can be paired with a variety of meters or controllers in the DV series to provide reliable, cost-effective measurements in a variety of applications. The robust, easy-to-install gauge system translates a thermoelectric voltage to a vacuum pressure based on the density of the gas. The thermocouple gauge tube/sensor, DV-5, is fully compensated for temperature and rate of temperature change with no suspended weld to an external heater.
DV-6 Series for Medium Vacuum
The Teledyne Hastings’ DV-6 series thermocouple vacuum gauge tube acts as a localized sensor which is then paired with a selection of meters or controllers to provide reliable, cost-effective measurements in diverse applications. The robust sensor gauge tube is easily installed into vacuum systems and when properly excited, generates a thermoelectric voltage to provide a vacuum pressure measurement based on gas density. The DV-6 thermocouple vacuum gauge tube fully compensates for temperature and rate of temperature change.
HPM 2002 Series Vacuum Gauge
The HPM-2002, dual sensor vacuum gauge, is a panel mount instrument with a microprocessor-based display unit, gauge tube, and interconnecting cable.

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. The 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.
HVG-2020B Wide Range Vacuum Gauge
The HVG-2020B wide-range, dual-sensor vacuum gauge takes measurement to the next level. With a Piezo-based sensor and a thermal-based Pirani sensor accurately and confidently measure pressures across seven decades. The Piezo sensor is media isolated, gas composition independent, and periodically zeroed by the Pirani sensor. An ambient thermal sensor enables the instrument to adjust for temperature and therefore better accuracy.
The optional touchscreen display, free Windows data acquisition software, and a variety of digital communication paths make the HVG-2020B flexible and user-friendly. Whether you need USB, RS 232, RS 485, linear or log outputs, or graphical displays for data acquisition logging, this wide-range gauge can perform.
