Smart Sensor AR866 Handheld Hot-Film Anemometer – High-Precision Telescopic Thermal Wind Speed & Air Volume Meter with USB PC Interface

The Smart Sensor AR866 is a professional-grade thermal (hot-wire) anemometer designed to deliver exceptional precision in low-velocity airflow environments. Unlike standard vane anemometers that struggle with micro-breezes, the AR866 utilizes an ultra-fine, electrically heated film sensor to detect microscopic air movements down to 0.01m/s. Equipped with a slender telescopic probe, this instrument is ideal for inserting directly into ventilation ducts, grilles, cleanroom diffusers, and tight structural spaces.

Key Features:

  • Advanced Hot-Film Thermal Sensing: Engineered for extreme accuracy in low wind speeds, providing a wide measuring span of $0 \text{ to } 30\text{m/s}$.
  • Slender Telescopic Probe: Extends smoothly to access hard-to-reach commercial HVAC ductwork, ceiling diffusers, and fume hoods safely.
  • Dual Volume & Flow Mapping: Simultaneously tracks Air Velocity ($m/s, ft/min, Knots, km/h, mph$) and Air Volume calculations ($CMM / CFM$) up to $999,900 \text{ m}^3\text{/min}$.
  • Massive 500-Group Data Storage: Built-in onboard memory allows technicians to save, review, and clear up to 500 groups of operational data right in the field.
  • USB Connectivity & Live Graphing: Includes a dedicated USB interface to connect directly to a PC for real-time data monitoring, continuous logging, and printing measurement curve graphics.
  • Vibrant Backlit LCD with Bar Graph: Displays wind parameters alongside a dynamic multi-segment analog bar graph and ambient temperature measurements ($0^\circ\text{C} \text{ to } 45^\circ\text{C}$) concurrently.
  • Type Digital Anemometer

Product Overview

Optimize commercial ventilation systems, secure cleanroom certification parameters, and manage aerodynamic lab environments with the Smart Sensor AR866 Hot-Wire Anemometer. Standard mechanical impeller wind meters lack the sensitivity required to audit low-flow draft leaks or precise HVAC balancing. The AR866 solves this problem by monitoring the minute cooling rate of its heated micro-sensor, yielding an exceptional 1% basic precision threshold.

Weighing just 153 grams and boasting automated Maximum/Minimum/Average calculation metrics, this instrument provides commercial facilities managers, energy auditors, and aerodynamicists with a laboratory-grade, field-ready data collection system.
