The VelociCalc 9555 series are portable, handheld, multi-function ventilation meters. These instruments are available with or without a differential pressure sensor and are designed to work with a wide range of plug-in probes. The probes allow users to make various measurements by simply plugging in a different probe that has the features and functions best suited for a particular application. They are designed to measure air velocity, temperature, humidity, carbon monoxide (CO) and carbon dioxide (CO₂). Calculations include air flow, heat flow, turbulence, wet bulb and dew point temperature. The probes can be ordered at any time and include a data sheet with certificate of traceability. When its time for servicing, only the probe needs to be returned since all the calibration data is stored within the probe. Professionals use this instrument for HVAC commissioning and troubleshooting, clean room certification, testing and balancing, ventilation evaluations, thermal comfort studies, indoor air quality (IAQ) investigations, and process air flow testing. Instrument includes the 964 straight probe (air velocity, temperature, and humidity), alkaline batteries, USB cable, LogDat2 & TrakPro downloading software, calibration certificate, operation & service manual, and hard carrying case. The 966 Articulating Probe for Air Velocity, Temperature, and Humidity, and the 982 IAQ Probe with CO are optional accessories (additional rental charges apply).
