Met One- 092 Barometer Pressure Sensor

A compact and accurate barometric pressure sensor designed for reliable atmospheric pressure monitoring across a wide range of environmental conditions, with flexible analog and digital outputs.

  • Wide pressure range (600–1100 hPa) suitable for sea level up to 10,000 ft elevation
  • High accuracy with ±0.35 hPa at 20°C and excellent long-term stability
  • Multiple output options: configurable analog (VDC) and digital (RS-232, RS-485, SDI-12)
  • Maintenance-free, factory-calibrated design in a small, weather-protected enclosure

Description

The Met One Instruments 092 Barometer Pressure Sensor is a compact and reliable instrument designed for precise atmospheric pressure measurements across a wide range of environments. With a measurement range of 600 to 1100 hPa and high resolution of 0.1 hPa, it delivers accurate performance from sea level up to 10,000 feet elevation. The sensor is fully temperature-compensated from −40°C to +55°C and operates in 0–100% relative humidity, making it well suited for meteorological stations, environmental monitoring, and industrial applications requiring stable and dependable pressure data.

Engineered for flexibility and ease of integration, the Met One 092 offers both analog and digital outputs, including RS-232, RS-485, and SDI-12, with user-configurable voltage ranges to match system requirements. Its low power consumption, rugged housing, and built-in protection from environmental exposure ensure long-term stability with no routine maintenance needed. Easy mounting via a U-bolt and constant factory calibration make this sensor a practical, long-life solution for accurate barometric pressure monitoring.
