Optimize airflow and diagnose system performance with precision instruments built for HVAC/R professionals.

Sper Scientific tools help you reduce energy costs, improve occupant comfort, and maintain building safety.

  • Airflow & Anemometers: Measure air velocity and volume flow to balance duct systems and verify ventilation performance.
  • Temperature & Humidity: Hygrometers and psychrometers for ambient condition monitoring, dew point analysis, and moisture control.
  • Thermal Imaging: Infrared cameras and thermometers to detect heat loss, insulation gaps, refrigerant leaks, and equipment hot spots.
  • Pressure & Differential: Manometers and differential pressure meters to measure static pressure, room relationships, and filter resistance.
  • Refrigeration Diagnostics: Temperature and pressure tools for verifying refrigerant charge, superheat, and subcooling.

From system commissioning and HVAC balancing to predictive maintenance and energy audits, Sper Scientific delivers the measurement accuracy HVAC/R technicians depend on.
