The testo VAC Smart Probe Set provides a combination of four Smart Probe instruments used with your Smart Device needed to test and balance a multi-outlet ventilation system. Two types of anemometers give you the capacity to measure in-duct air flow and the flow from each vent. Using an IR temperature probe for surface temperatures will show you motor and electrical equipment conditions and an easy check of each outlet. The thermohygrometer will provide an assessment of the humidity and dewpoint concerns throughout the system.

• Measures air velocity, temperature, relative humidity, wet bulb / dew point, and calculate volume flow
• Kit includes instruments to measure, balance, troubleshoot, and optimize ventilation systems performance
• RH and air flow measurements in-duct and at registers viewed simultaneously in the testo Smart Probes App (605i, 405i, 410i)
• App calculates system enthalpy with air flow and RH probes; App allows you to photograph objects with smart device, capturing measurement marker and temperature values for reference and reporting (805i)
• Includes: Thermal Anemometer 405i, Vane Anemometer 410i, Thermohygrometer 605i, Infrared Thermometer 805i, Smart Case (VAC), batteries, and certificate of calibration
