Barograph NSII-BQ

The Vaisala PTU300 combined barometric pressure, relative humidity and temperature in one transmitter. The series is discontinued and has been replaced by a suitable Indigo520 barometric-pressure configuration with an application-specific HMP probe.

• Legacy three-in-one pressure, humidity and temperature transmitter
• PTU301, PTU303, PTU304, PTU305, PTU307 and PTU308 variants
• Former applications include laboratories, meteorology and semiconductor measurement
• Current replacement platform: Indigo520 with barometric-pressure measurement
• Humidity probe selected according to mounting and process conditions
• Existing wiring, outputs and process connections require migration review

The Vaisala PTB330 provides accurate, stable barometric-pressure measurement for professional meteorology, aviation, maritime systems, laboratories and demanding environmental applications.

• 500 to 1100 hPa or extended 50 to 1100 hPa pressure range
• Accuracy up to ±0.10 hPa at +20 °C
• Choice of one, two or three Vaisala BAROCAP® pressure sensors
• Optional graphical display with trends and measurement history
• RS-232 with optional RS-485, RS-422 and analogue outputs
• WMO pressure trend and tendency calculations
• IP66 housing without display for demanding installations

The Vaisala PTB110 is a compact, low-power barometer for accurate atmospheric-pressure measurement and integration with data loggers, weather stations and environmental monitoring systems.

• Selectable barometric-pressure ranges from 500 to 1100 hPa
• Accuracy up to ±0.3 hPa at +20 °C
• 0–2.5 V, 0–5 V or frequency-output options
• Less than 4 mA current consumption
• External trigger supports power-saving operation
• Compact DIN-rail-mountable construction

The Sato Baromex 7612-00 combines an easy-to-read analogue barometer with a digital thermometer for local atmospheric-pressure and room-temperature indication.
