Piezo-Pirani Vacuum Gauge HVG-2020B
The HVG-2020B vacuum gauge features two sensors, a piezo-based transducer and a thermal-based Pirani sensor, in a single small package. The Piezo is used at higher pressures, above 10 Torr, is media-isolated and is also gas composition independent.
The Pirani sensor is a precision welded hot-wire thermal sensor that measures pressures below 1 Torr. An ambient thermal sensor enables the instrument to make adjustments for temperature which in turn enables better accuracy throughout the pressure range of the instrument (0.1 mTorr to 1000 Torr). Between 1 and 10 Torr, a weighted average between the two sensors is used to determine the pressure. The HVG-2020B also features cross-calibration. In short, the low pressure Pirani is able to periodically zero the piezo sensor which gives the user superior accuracy performance.
The HVG-2020B is easy to install, and the optional display provides the user with several different views, or modes of operation. It is very flexible and can provide both analog and digital output to easily integrate into process control. A wide variety of analog output signals may be selected. This makes the HVG-2020B an excellent choice to replace more expensive capacitance manometers.
Free Windows data acquisition software for data logging is available for the HVG-2020B.

Piezo Vacuum Gauge HVG-2020A
The HVG-2020A vacuum gauge is a media-isolated, gas composition independent, piezo-resistive instrument that provides accurate pressure measurement throughout the rough vacuum region. Unlike thermal based vacuum gauges, the HVG-2020A directly measures the pressure in the system. It does not infer the pressure by measuring the thermal conductivity of the gas. This means that the readings do not depend on the type of gas being used.
The HVG-2020A is easy to install, and the optional display provides the user with several different views, or modes of operation. The “Pressure versus Time” Mode allows the user to monitor the pump-down (or vent) of their vacuum system. Rate-of-rise can be viewed and may help to identify the presence of a chamber leak. For users who want another method to see system pressure changes, we provide the “Bar Graph” Mode.
The HVG-2020A is very flexible and can provide both analog and digital output to easily integrate into process control. A wide variety of analog output signals may be selected. 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.

From refrigeration to vacuum furnaces, from freeze drying to pharmaceutical production, the DV-Series thermocouple gauge tubes operate under the most demanding conditions or rugged environments and are the economical solutions to most low and medium vacuum pressure measurements and control needs.
DV-4 Series
Range: 0,1 to 20 Torr
DV-5 Series
Range: 0,1 to 100 mTorr
DV-6Series

Teledyne Hastings Thermocouple Gauge Tubes/Sensors are fully compensated for both temperature and rate of temperature change and are corrosion resistant. The robust, easy to install gauge system translates a thermoelectric voltage to a vacuum pressure based on the density of the gas.
Chose from various fittings and materials of construction.
The DV-4 /DV-5 / DV-6 Series vacuum gauge tubes can be paired with a variety of Teledyne Hastings’ meters or controllers to provide reliable, cost effective measurements in a variety of applications.
The THI vacuum gauges or controllers do not require recalibration when thermocouple gauge tubes are replaced further decreasing process down time. However, our DB-16D / DB-18 / DB-20 reference tube is available to confirm meter/controller performance. Installation accessories are also available to support your installation needs.
HPM 4/5/6 Portable Vacuum Meter
The Teledyne Hastings Instruments’ HPM 4/5/6 is a hand-held, battery-operated digital vacuum gauge. Its reputation has been built on exceptional stability, accuracy, and reliability under the most demanding conditions.
The HPM 4/5/6 features a precision A/D converter along with a microprocessor to measure the thermocouple vacuum gauge tube’s signal output. The microprocessor converts the measurement to a pressure reading by employing the gauge tube’s well-defined output/pressure relationship. The result is displayed using a bright, easy-to-read graphical display.
The HPM 4/5/6 works with three of THI’s most popular gauge tube families: DV-4 (0.1 – 20 Torr), DV-5 (0.1 – 100 mTorr) and DV-6 (1 – 1000 mTorr). Tubes are matched and interchangeable without calibration adjustments.

VT/CVT Analog Vacuum Gauge Meters and Controllers
Teledyne Hastings Instruments (THI) VT-Series Vacuum Gauges impress with an exceptional stability, accuracy, and reliability under the most demanding conditions.
VT-Series Vacuum Gauges are available in three standard ranges: 0-100 mTorr, 0-1000 mTorr, and 0-20 Torr. A self-contained gauge circuit is attached to the rear of the direct reading meter. All VT-Series Vacuum Gauges feature long life and minimal maintenance. These instruments utilize THI’s rugged but sensitive noble metal Thermocouple gauge tubes (DV-4, DV-5, DV-6) that are designed specifically for each range. Tubes are matched and interchangeable without calibration adjustments.
THI Vacuum Controllers, CVT series are fully automatic, continuous-reading instruments for unlimited vacuum applications. These controllers operate in the same standard ranges as the VT meters with the addition of double user selectable control limits. The control points are durable 5 amp single pole double throw relays which can be configured normally open or normally closed.
DVT/DCVT Digital Vacuum Gauge Meters and Controllers
The Teledyne Hastings Instruments’ DVT & DCVT are digital readout versions of the successful VT/CVT-Series “Hastings Gauges” packaged in a 1/8 DIN case which can be panel mounted. The Digital VT/CVT Vacuum Gauge Meters are available for THI’s most popular gauge tube families: DV-4, DV-5 and DV-6.
They feature a precision A/D converter along with a microprocessor to measure the thermocouple vacuum gauge tube’s signal output that is converted to a pressure reading by employing the gauge tube’s well-defined output/pressure relationship. The result is displayed using a bright 3-digit green LED display.
The DCVT includes several enhanced features which makes it an attractive solution for many vacuum control automation applications. It provides linear analog output (voltage or current) for integration of vacuum measurement with a PLC or other data acquisition system. In addition, the DCVT provides RS232 communication for direct connection to a PC. The DCVT also includes two independent user selectable set point relays for process control.
NIST Traceable Reference Tubes
The Teledyne Hastings Instruments Reference Tubes DB-16D, DB-18, and DB-20 permit a quick and easy recalibration of THI Vacuum Gauge Indicators by merely plugging the instrument into the reference and adjusting the calibration “current set” potentiometer until the instrument reads the exact pressure noted on the reference tube. The customer now knows his instrument is correctly calibrated.
THI Reference Tubes employ the same noble metal thermopile used in all THI Thermopile Vacuum Gauge Tubes. The thermopile is sealed in a glass capsule that has been evacuated, baked, outgassed, sealed, and aged to ensure stability over long periods of time. The sealed capsule is then housed in a protective metal shell to provide a rugged, trouble-free assembly.
