Product Description:
Honeytek HK820 Digital Anemometer is a professional-grade, handheld instrument designed for precise measurement of air velocity and ambient temperature. Built with durability and user-friendliness in mind, it features a robust, ergonomic design with a bright LCD display for clear readings in any lighting condition. The device utilizes a magnetic induction wind speed sensor for reliable performance and includes essential functions like MAX/MIN/Avg hold, data hold, and auto power-off to conserve battery life. Ideal for HVAC technicians, environmental engineers, and industrial safety personnel, the HK820 provides accurate, real-time data across multiple units of measurement.
Highlights
- Dual Measurement: Accurately measures both Air Velocity (m/s, km/h, ft/s, knots, mph, ft/m) and Temperature (°C/°F).
- High Precision Sensor: Equipped with a Magnetic Induction Wind Speed Sensor and a negative temperature coefficient sensor for reliable results.
- Multi-Unit Display: Easily switch between 6 different air velocity units and °C/°F for temperature.
- User-Friendly Interface: Large, backlit LCD display with bargraph for intuitive reading. Simple button controls for mode, units, max/min, and data hold.
- Essential Functions: Includes Data Hold, MAX/MIN/Avg value capture, and Auto Power Off (shuts down after 15 minutes of inactivity).
- Durable Design: Compact, rugged housing with a comfortable grip for field use.
- Low Battery Indicator: Ensures you’re never caught off guard by a dead battery.
- Long Battery Life: Powered by 3 x AAA batteries (included).
