Digital manometers
Our digital manometers for mobile measurement of positive and negative differential pressure
The portable, battery-powered digital pressure manometers measure positive and negative differential pressure. Their ease of use makes them ideal for customer service and maintenance work, e.g. on heating, ventilation and air-conditioning systems, for measuring chimney drafts and for filter monitoring. Due to their accuracy and good reproducibility of results, the digital manometers are also ideally suited for laboratory work.
Advantages of digital manometers
- High accuracy and long-term stability
- Low zero drift, hysteresis and temperature dependence
- Optimal for mobile use due to battery operation and manual zeroing functions
Features of the digital manometers

Calibrations
To ensure the reliability of your pressure transmitters, we offer in-house calibrations and calibration certificates according to DKD guideline 6-1 or within the scope of ISO 9001. Learn more about our calibrations here.
Application of the digital manometers
In air conditioning systems and cleanrooms, many pressure values must be checked after commissioning and in the course of maintenance or validation. For example,
- the fan pressure,
- the pressure drop across units and filters,
- the overpressure in the cleanroom,
- the flow in the ventilation duct and rooms must be precisely measured and documented.
The digital manometers of the EMA family are optimized for long-term use in building services and industrial environments. They are easy to operate and robust.
