GENERAL HWA4214 SD Data Logging Airflow Meter

Features: Embedded Microcontroller: Custom one-chip LSI device Parameters Measured: Air speed, temperature Data Logging Sampling Time: 1 second to 1 hour Settable Parameters: Date, time, auto power off, beep sound, sampling time, decimal point or comma decimal division, temperature unit, air speed unit, optional thermocouple type ( K or J) Storable/ Recallable Readings: Maximum, minimum SD Card Capacity: 1 GB to 16 GB Accurately Measures Air ( wind) Speeds as Low As 0.5 mpg and Air Temperatures within ± 1.5° F ( ± 0.8° C) . Applications include environmental testing, maintenance and repair of air conveyors and flow hoods in clean rooms, calibrating low-speeds fans and blowers, balancing velocity profiles in furnaces and refrigerated cases and precision calibration of HVAC/ R systems. This instrument' s unique feature is its patented technique for storing sampled data in Excel format on removable SD memory cards.
