Barometer GFTB 200

GFTB 200

Precision barometer, hygrometer, and thermometer

- Measurement of air humidity, temperature, and atmospheric pressure in a single device

- Additional calculation of: Dew point temperature, wet bulb temperature, content

  of air humidity and absolute humidity

- Minimum/maximum value memory for all magnitudes

- High precision thanks to digitally stored characteristic curves

- Absolute zero and slope correction in ultra-fast adjustment

- Altitude correction above sea level

- Continuous operation as a climate center possible (extremely low consumption)

- High precision sensors

- Indication of atmospheric pressure trend (increasing/decreasing).

Aplicaciones

Measurement in a matter of seconds of atmospheric pressure, air humidity, temperature, and other derived magnitudes in computer rooms, museums, galleries, churches, offices, homes, warehouses, greenhouses, swimming pools, production rooms, refrigeration and ventilation units, damage inspections, constructions, building physics, etc. The use of high-precision sensors allows the equipment to achieve greater accuracy compared to similar equipment. With additional indication possibilities of "dew point temperature TD", "wet bulb temperature TwB", "absolute humidity [g/m³]" and "air moisture content [g/kg]", the state of the air can be clearly and accurately determined. Thanks to its low consumption, the device can be used permanently, e.g., as a "climate central unit."
