Bộ đo vận tốc gió, lưu lượng gió, nhiệt độ, độ ẩm và BTU


Measure air velocity, air volume, temperature, humidity, and BTU with the Model 8912 Vane Thermo-Anemometer. The large 1.7" (44 mm) display allows users to easily view readings. User-selectable wind speed units include ft/min, m/s, knots, mph, and km/hr. In addition to these functions, the 8912 is capable of measuring relative humidity, wet bulb temperature, dew point, and BTU capacity. A built-in sensor records ambient temperature in °F or °C. Model 8912 features include data hold, the ability to record minimum, maximum, and average readings on a single point, and an RS-232 interface setting. The Model 8912 also features a detachable probe for easy replacement, if necessary. The units can record and average up to 2 hours of data while displaying the continuous running average. Each unit includes hard carrying case, four AAA batteries, calibration data tag and instruction manual. This versatile meter is perfect for HVAC inspection, energy audits and balancing applications.
