Supported Applications
The Omega HHP360 Barometric Smart Manometer is a microprocessor-based, handheld device designed to measure absolute pressure relative to zero. It functions as a precision barometer and altitude meter suitable for field or laboratory conditions. The series supports the measurement of local pressure, sea level-corrected barometric pressure (based on user-set height), and altitude derived from a user-defined datum.
Documented operational modes include:
- Absolute pressure sensing
- Barometric pressure corrected to sea level
- Altitude display in feet or meters
- Pneumatic system leak testing (rate of leakage determination)
- Data logging for up to 240 readings via automatic intervals or manual capture
Operating Conditions & Performance
The HHP360 series operates within an ambient temperature range of -5 to 50°C (23 to 122°F) and can be stored between -40 to 60°C (-40 to 140°F). Accuracy specifications vary by model variant, with thermal errors included in the stated values across the operating temperature span.
- HHP360-A: ±0.02% FS
- HHP360-B (Low Range): ±0.015% FS from 0 to 19.337 psia (0 to 1000 mmHgA)
- HHP360-B (High Range): ±0.025% FS from 19.338 to 38.674 psia (1000 to 2000 mmHgA)
The device features a safe overpressure rating of 77 psia (4000 mmHg). The display is a 5 significant digit LCD with adjustable contrast, showing two lines of 16 alphanumeric characters. A green backlight indicates normal operation and changes to red during an overpressure event.
Configuration Options
The series offers configurable measurement ranges and unit selections tailored for specific pressure spans. The HHP360-A covers a range of 0 to 17.403 psia (0 to 900 mmHg, 0 to 35.433 inHg), while the HHP360-B extends to 0 to 38.674 psia (0 to 2000 mmHg, 0 to 78.740 inHg).
Key configurable and fixed features include:
- Housing & Materials: Polycarbonate case with a sealed keypad; wetted parts are constructed of 316 SS.
- Process Connection: ¼ NPT female fitting (316 SS).
- Power Supply: Operates on four "AA" batteries, providing greater than 100 hours of continuous use. Batteries are included in the package.
- Units of Measure: Displays pressure in mmHg, inHg, PSI, mbar, bar, kPa, or Torr; altitude is displayed in feet or meters.
- Data Functions: Includes Tare, Min/Max capture, selectable damp rates, auto shut-off, and a leak test mode. Data logging supports automatic readings every 5 seconds for 20 minutes or manual entry up to 240 points.
Key Product Differences
The HHP360 series is distinguished by two primary model variants based on measuring range:
- HHP360-A: Precision absolute manometer with a 0 to 900 mmHg (0 to 17 psia) range.
- HHP360-B: Precision absolute manometer with a 0 to 2000 mmHg (0 to 38 psia) range and dual-segment accuracy specifications.
All units include an operator's manual, NIST traceable calibration certificate, four "AA" batteries, and a protective rubber boot. The device dimensions are 165 H x 91 W x 57 mm D (6.5 x 3.6 x 2.25") with a weight of 400 g (14 oz).
