OMESS – CALIBRATORS
streifen

ONNEKEN produces since 1973 pressure-calibrators of high-quality and reliability.

Our calibrators find their various applications in fields of pharmaceutical- medical sectors, automobile industry, energy supply or heavy industry. The high quality standard and longterm stability is given through the Swiss pressure gauges from HUBER INSTRUMENTS AG, which we built-in in our calibrators.

For special applications we also develop individual calibrators or equipment.

MANOMETERS
streifen

A convincing feature of HUBER digital handheld pressure gauge is its versatility, longtermstability, reliability and high standard. It permits measurements in over-and underpressure, differential or absolute pressure.Functions are available for leak rate, min./max. values and for storing the measured values in the display. The measured values can be stored in the integrated data memory with the datalogging function and from there, logged directly on a connected printer (without PC) via the RS232/ IR interface.

HM-30
The Meteo Station HM30 is used to collect, record and evaluate climatic data in real-time. The instrument registers the barometric air pressure (altitude measurement), relative air humidity and temperature. Its range of possible applications is extended by comprehensive functions, such as programmable alarm levels and trend indicators. Long-term observations can be made by selecting the measuring interval and storing the measured values in an integrated memory. A climate software with comprehensive functions is available for Windows. This enables the HM30 to be remote controlled from a PC. Graphics and lists can be created, and data exported.

Application:
collecting, recording, evaluating climatic data
