Pressure measurement in cleanrooms, air conditioning and OEM applications

 

You need to control the pressure in your cleanroom, to protect it from contaminated air. You need to supervise an air filter or a fan in the field of air conditioning. Your machine needs to have an underpressure or overpressure maintained. Or the volume flow within your air duct shall be measured.

halstrup-walcher offers both standard and customer specific solutions for high-level pressure measurement applications. We look forward to helping you sense every single Pascal!
