APPLICATIONS

APPLICATIONS

The PRO 921/925 multiparameter handheld meters are designed for a wide range of professional applications where precise measurement and data logging are essential:

    • HVAC System Monitoring:
      Measure and log temperature, humidity, pressure, and air quality parameters for heating, ventilation, and air conditioning system diagnostics and commissioning.

    • Building and Energy Audits:
      Simultaneously monitor surface temperature, climate/humidity, and differential temperatures to assess building insulation, detect thermal bridges, and optimize energy efficiency.

    • Industrial Process Control:
      Use interchangeable DX-series digital probes to monitor critical parameters in industrial environments, supporting process optimization and quality assurance.

    • Laboratory and Research:
      High accuracy and robust design make the PRO 921/925 ideal for laboratory measurements, experiments, and long-term data collection.

    • Field Service and Maintenance:
      Portable, impact-resistant construction and IP67 protection (except TC inputs) make these meters suitable for demanding fieldwork, including equipment maintenance and troubleshooting.

    • Environmental Monitoring:
      Combine temperature, humidity, and air quality probes to monitor environmental conditions in greenhouses, storage facilities, and sensitive production areas.

    • Data Logging for Compliance:
      The PRO 925’s data logger stores up to 1 million data sets with date/time stamps, supporting regulatory compliance and detailed reporting in various industries.
