• Includes plug-in 120 VAC charger, 12 volt car adaptor, sensor case with snap-on belt clip and PC interface cable with software;
• Colr LED's can be programmed to provide quick indication of CO₂ concentration range;
• Overnight self-calibration feature will calibrate sensor to background CO₂ concentrations;
• Gold plated optical sensor ensures long-term durability and stability;
• Purposefully built for quality designed and built using Internationall Certified ISO 9001 processes.

The AirTest PT-9250 can help you better understand ventilation in a building and easily identify and solve problems related to fresh air ventilation.

• • Measure zone level fresh air ventilation rates to determine if spaces are over or under ventilated;
  • Quantify opportunities for energy savings with CO₂ ventilation control;
  • Quickly investigate air quality problems to determine if lack of ventilation is an issue;
  • Quickly check to ensure a ventilation/mechanical system is working properly;
  • Trend log CO₂ and temperature concentrations over time to determine if occupancy profiles correspond to system operation time sequences;
  • Use as a verification tool to verify that new/retrofit eqiupment installations or air balance are providing optimum ventilation to each occupied zone;
  • Discover areas affected by combustion exhaust.  (CO₂ is a major byproduct of combustion.)
