The reference class in pocket size


The primary focus in the development of the new G 1100 series was placed on the essential functions of the measurement technology. The heart of the instrument, the sensor, is a high-class component which excels in this instrument class. The high reliability, speed and precision of the G 1100 variants, packed in a compact and water protected housing makes the instruments an ideal partner of industry and craft sector.

For fast measurements in meteorology, aviation and motor sports, hiking, cycling and many more.

Fast, precise and high resolution:

Resolution 0.1 hPa (mbar) and resolution of the altitude display derived from pressure 0.1 m! As a reference for countless devices with integrated barometric sensor. Barometric sensors are used in countless applications: examples are vehicles with combustion engines (air pressure as an important parameter for engine control), altimeters (calculation of altitude using barometric altitude formula), navigation systems, smartphones and of course in weather stations. But is the absolute pressure displayed correct? Thanks to optional calibration certificates the barometer can serve as a perfect reference instrument for checking the actual accuracy of corresponding devices.

Demand Flow Regulator

The best and most accurate way to calibrate your gas sensors – Calibration simplified.

Our Demand flow regulator for use with instruments containing internal sample pumps, such as the Cortex MetaLyzer 3B-R3, Cortex MetaMax 3B-R2 or Servomex analysers. For use with all 110 litre cylinders.

The intended use of the Demand Flow Regulator is to provide a flow of gas of between 0 and 3 litres per minute to a variety of gas detection instruments fitted with an internal pump to draw gas from the cylinder.

When calibration is complete, disconnect any tubes before attempting to remove the regulator from the cylinder.
Upon removal of the regulator from the cylinder, a slight ‘hiss’ of gas may be heard as the pressure in the head space of the regulator is released. This is entirely normal and disconnection should take place in a well-ventilated area.

3 Litre Calibration Syringe Triple V outlet

The Cortex Calibration Kit is also available without the 3 Litre Calibration Syringe for systems that are using the disposable turbines.
