Humidity measurement
Hans Buch supplies solutions for humidity measurement and monitoring in industrial applications. We advise on sensors, transmitters and complete systems for measuring relative humidity, dew point and water vapour – tailored to industries with stringent requirements for process control, quality and documentation.
Moisture is invisible, but its consequences are not.
Mould in the warehouse. Faults in electronics. Scrapped production batches. Too many businesses discover humidity problems too late – and the cost is high. Hans Buch helps you keep humidity levels under control with precise measurements and sound advice.
Humidity is more complex than most people think
Relative humidity, absolute humidity, dew point, water vapour content – there are many ways to describe moisture, and the right measurement parameter depends entirely on your application. Choosing the wrong sensor for a drying system or cleanroom can produce misleading data that proves costly.
This is where our advice makes a difference.
From sensor to system – we cover the entire solution
- Capacitive and resistive humidity sensors for fixed industrial installations, cleanroom environments, storage and process control – we match the sensor to the environment, not the other way round.
- Dew point meters for applications where absolute dryness is essential – compressed air, gas treatment and critical production environments.
- Handheld meters and data loggers for spot checks, documentation and temporary monitoring during, for example, construction work or quality inspections.
- Transmitters with system integration via 4-20 mA, HART, Modbus or digital protocols – we ensure your humidity data reaches the right places in your plant or BMS.
| Challenge | Solution |
| Condensation and moisture damage in production facilities | Continuous monitoring with alarms |
| Unstable drying processes | Precise inline measurement with a transmitter |
| Documentation requirements in GMP environments | Validated equipment and calibration certificates |
| Moisture in compressed air | Dew point meter for pressurised media |
| Climate control in archives and museums | Stable RH sensors with data logging |
Industries with specific humidity requirements
Humidity control is not the same across industries – and our solutions should not be either:
- Cultural institutions – climate protection for collections and archives
- Pharmaceuticals and medtech – validated systems, IQ/OQ documentation
- Timber and furniture industry – drying optimisation and moisture balance in raw materials
- Electronics manufacturing – ESD-safe dry environments and cleanrooms
- Food and refrigeration – HACCP documentation and shelf-life assurance
