We at Teledyne Hastings Instruments are pleased to introduce the newest member of our vacuum measurement portfolio, the HVGPR. The HVGPR vacuum gauge measures pressures from Atmosphere to 0.1 mTorr (1.3 x 10-4 mbar / 1.3 x 10-2 Pascal). It uses the same precision pirani sensor found in our proven HVG-2020B wide range gauge. The HVGPR is packaged in a compact and cost-effective design that makes it ideal for OEMs, system integration, and process automation.
The HVGPR measures from Atmosphere through Medium Vacuum (0.1 mTorr / 1.3 x 10-4 mbar / 1.3 x 10-2 Pascal). It has great accuracy from 1 mTorr to 100 mTorr while still providing visibility at atmosphere. Most applications use N2 or Air, but the HVGPR has preset gas correction factors to also cover He, Ar, H2, CF4, and SF6.
| Range | Accuracy |
| 100 Torr to 1,000 Torr | ± 50% of Rdg |
| 1 mTorr to 100 Torr | ± 15% of Rdg |
| 0.1 mTorr to 1 mTorr | ± (50% of Rdg + 0.1 mTorr) |
The HVGPR is available with two small system connections for system integration: KF-16 flange or 1/8” MNPT. Unlike some pirani vacuum gauges, the HVGPR can be mounted and operate in any orientation: port facing down, port facing up, port facing sideways, port tilted at an angle, etc.
Both models offer two choices of common logarithmic analog output signals for simple integration into OEMs and process automation: 1 V/decade (2-9 VDC) or 1.286 V/decade (1.16-10.1620). The user can easily change from one output to the other. In addition, RS485 digital communication is standard on all units. Power, analog output, and digital communication are provided through a single RJ45 connector.
| Output | @ 0.001 Torr | @ 1,000 Torr | P (Torr) from V (volts) | Volts from P (Torr) |
| 1.00 V/decade | 2.0000 V | 9.000 V | P=10(v-6) | V=log10P+6 |
| 1.286 V/decade | 1.1600 V | 10.1620 V | P=100.778(V-6.304) | V=1.286 log10P+6.304 |

The gauge offers three simple ways to Zero or Span the unit:
Recessed Push Button,
Remote Pins 7 & 2
RS485
The HVGPR is ideal for a wide variety of vacuum applications, but it’s compact size and flexibility make it excellent for OEMs, system integration, and process automation.
