Supported Applications

The Omega HHP680 is a handheld digital manometer designed for measuring pressure in water column units (in WC). The series identity centers on low-cost, versatile portable measurement. Typical applications documented include commercial and automotive HVAC.

Operating Conditions & Performance

The HHP680 operates within an ambient temperature range of 0 to 40°C (32 to 104°F) with a relative humidity rating of 15 to 90% RH, non-condensing. Storage is supported from -20 to 60°C (-4 to 140°F). The device utilizes a solid-state sensor and features a measurement range of 0 to 20 inH2O (water column) with selectable resolution options of 0.01" or 0.1".

Accuracy is specified as ±2% at 23°C (73°F), valid within an operating temperature window of ±5°C (9°F) and less than 75% RH. The compatible media are dry, non-corrosive gases. Power is supplied by four "AAA" alkaline batteries with a typical life of 150 hours; no measurable current draw occurs when the unit is in the off position.

Configuration Options

The HHP680 series includes specific accessories and configuration options as part of its standard package. The handheld manometer features a 3½ digit LCD display with a maximum reading of 1999. A low-battery indicator is displayed when voltage drops below the operating level.

  • Process Connection: Includes a ¼ NPT fitting and 60 cm (24") tubing for pressure measurement.
  • Housing & Portability: Dimensions are 190 H x 44 W x 40 mm D (7.5 x 1.7 x 1.6"). The unit weighs approximately 150 g (5.3 oz) with batteries and includes a soft carrying case.
  • Power: Operates on four "AAA" alkaline batteries, which are included in the package.

Key Product Differences

The series is represented by the single model HHP680. The product overview describes it as a portable manometer with a 0 to 20 inH2O range. No additional variants, alternative ranges, or optional sensor types are documented within this bundle.
