Supported Applications
The Dwyer Model 9671 Multifunction Vane Thermo-Anemometer is a handheld datalogger designed for air flow measurement. The series measures velocity, humidity, temperature, wet bulb, and air volume parameters to support HVAC testing and airflow analysis.
Operating Conditions & Performance
The Model 9671 operates across specific ranges with defined accuracy and response times:
- Air Velocity: Range of 118 to 6299 ft/min (0.6 to 32 m/s) with an accuracy of ±5% of reading or last significant digit (whichever is greater). Resolution is 0.1 ft/min (0.1 m/s), and response time is 1 second.
- Air Volume: Range of 0 to 99999 CFM or m³/s with an accuracy of ±5% of reading or last significant digit (whichever is greater). Resolution varies by range: 0.1 for values 0 to 9999.9, and 1 for values 10000 to 99999. Response time is 1 second.
- Temperature: Range of -4 to 140°F (-20 to 60°C) with an accuracy of ±1°F (±0.6°C). Resolution is 0.1°F/°C, and response time is 60 seconds.
- Relative Humidity: Range of 0 to 100% with an accuracy of ±3% @ 25°C from 10 to 90% RH; ±5% outside this range. Resolution is 0.10%, and response time is 60 seconds.
- Wet Bulb: Range of -7.6 to 158°F (-22 to 70°C) with a resolution of 0.1°F/°C.
The device features a vane diameter of 3" (77 mm), weighs 6 oz (170 g), and includes CE approval. Power is supplied by four AAA alkaline batteries, providing approximately 100 hours of battery life.
Configuration Options
The Model 9671 series supports multiple measurement modes to accommodate different data collection needs:
- Single Point Measurement: Captures a single reading with no memory storage.
- Multiple Point Measurement: Allows for editable file names and stores up to 99 points. Users measure and store by pressing specified keys.
- Automatic Logging (Datalogging): Supports programmable datalogging with a capacity of 2400 memory points. Files are named with the default date and time. The system automatically measures and stores data according to pre-set parameters, including Begin-Date, Start-Time, End-Date, Suspend-time, and sample rate.
Communication is handled via an RS-232 interface (9600 bps, 8 data bits, no parity) using a PS/2 PLUG connector. The unit includes a display measuring 1 x 1.8" (26 x 45 mm). Accessories available for the series include replacement probes: A-551 (Replacement Probe with Vane) and A-VT300-P (Replacement Probe with Miniature Vane).
Key Product Differences
The Model 9671 is offered as a complete kit including the meter, hard carrying case, batteries, software CD, RS-232 cable, and instruction manual. The series supports interchangeable probes to adapt to different measurement scenarios: the standard vane probe (A-551) or the miniature vane probe (A-VT300-P). While BTU calculation is listed as a function in the product overview, specific technical specifications such as range, accuracy, and resolution for BTU are not provided in the documentation.
