HUMIDITY AND AIR FLOW DAFM3 Digital Air Flow Meter The DAFM3 anemometer/psychrometer is designed with six HVAC/R essential parameters in one instrument. Conveniently combined into a portable, battery-operated instrument for measuring relative humidity, air temperature, dew point, wet bulb, air velocity and air volume. Measures • Air velocity, temperature and relative humidity Calculates • Wet bulb, dew point, and air volume (CFM, CMM) • Protective twist cap protects sensor when not in use.

F E AT U R E D P R O D U C T NEW AQM4 Air Quality Lit #349 The AQM4 meter measures CO2 levels, CO levels, air temperature, dew point, wet bulb temperature, and humidity. The AQM4 is an ideal instrument for indoor air quality (IAQ) diagnosis. The portable AQM4 uses NDIR (non-dispersive infrared) technology for CO2 measurement to ensure reliability and long-term stability. It is useful in verifying HVAC systems performance and air ventilation control.
