Digital Thermo-Anemometer Four Field Selectable Ranges from 500 to 15,000 FPM
AIR VELOCITY SPECIFICATIONS: Service: Air. Range: Field selectable 0-500, 0-1500, 0-5000, 0-15000 FPM (see chart below for metric conversions). Accuracy: Depending on range (see chart below) @ 59 to 86°F (15 to 30°C). Outside this range add 0.11% per °F (0.2% per °C). Temperature Limits: Probe: 0 to 200°F (-18 to 100°C). Ambient: 32 to 104°F (0-40°C). Display: 4-1/2 digit 0.4" high. Resolution: 1 FPM/0.1 MPS. Response Time: 15 seconds. Power Requirements: 9 volt alkaline battery, included. Probe: 5/16" (8.13 mm) diameter probe with integral hand grip and 6 ft. (15.2 cm) coiled cord. Length of probe: Model 471-1 = 25.4 cm Models 471-2 , 471-3 = 83 cm Weight: 12 oz (340 g).
TEMPERATURE SPECIFICATIONS: Range: 0 to 200°F (-18 to 100°C). Accuracy: ±2°F (1°C). Temperature Limits: Probe: 0 to 200°F (-18 to 100°C). Ambient: 32 to 104°F (0 to 40°C). Display: 4-1/2 digit 0.4" high. Resolution: 0.1°. Response Time: 30 seconds. Note: Ranges are field selectable.
