The Kurz Series 2440 portable flow meters from HMA Instrumentation provide air flow measurements in mass, volume, and velocity. It is designed for measuring ducts, pipes, stacks, vents, on-site calibrations, and airflow traverses. Models range from lab-grade to industrial high heat.
Features include:

• The highest repeatability, accuracy, and reliability available
• The fastest response to temperature and velocity changes in the industry
• Constant temperature thermal technology
• Excellent sensitivity to low velocities
• Insensitive to dirt and particulates in the flow stream
• Insensitive to installation angle
• 1 500 point data memory for recording traverses and other measurements
• Internal and exportable data logging
• Completely field configurable using the local user interface
• User-configurable low velocity cut-off, reference conditions, time constraints and flow area
• Built-in flow totalisers and elapsed time
• Velocity‐temperature mapping for wide-ranging velocity and temperature
• Sensors do not overheat at zero flow by using a unique constant temperature control method and power-limiting design
• Sensor lead-length independent circuitry

Applications:

• Industrial hygiene
• Survey tests
• HVAC supply and return ducts, grills, diffusers and testing
• Flow balancing
• Cleanrooms
• Fume hoods
• Combustion air velocity and flow calibration
• Duct, stack and pipe velocity traverses
• Coal-fired power plant stacks
• Research and development
• General-purpose air flow measurements
