The HHF42 is an economical air velocity meter solution for any air flow measurement application, such as, air conveyors, flow hoods, balancing, fans/motors/blowers, furnace velocities, refrigeration cases, paint spray booths and environmental testing. The portable HHF42 flow meter provides fast, accurate readings with digital readability and the convenience of a remote probe. The combination of hot wire and standard thermistor delivers rapid and precise measurements even at low air velocities. The microprocessor circuit assures the maximum possible accuracy and provides special functions and features.
