Your purchase of this HOT WIRE ANEMOMETER makes a step forward for you into the field of

precision measurement.

Although this ANEMOMETER is a complex and delicate instrument, its durable structure will allow

many years of use if proper operating techniques are developed. Please read the following

instructions carefully and always keep this manual within easy reach.

Features

1. Thermal anemometer, available for very low air velocity measurement.

2. Slim probe, ideal for grilles & diffusers.

3. Combination of hot wire and standard thermistor, deliver rapid and precise measurements

even at low air velocity.

4. Records Maximum and Minimum readings with recall.

5. Microprocessor circuit assures maximum possible accuracy, provides special functions and

features.

6. Super large LCD with dual function meter’s display, read the air velocity & temp. at the same

time.

7. Records Maximum and Minimum readings with recall.

8. Data Hold.

9. Power supply by 9V battery.

10. The portable anemometer provides fast, accurate readings, with digital readability and the

convenience of a remote probe separately.

11. Multi-functions for air flow measurement: m/s, km/h, ft/min, MPH, Knots.

12. Build in temperature °C, °F measurement.

13. Thermistor sensor for Temp. measurement, fast response time.

14. Used the durable, long-lasting components, including a strong, light weight ABS-plastic

housing case.

15. Deluxe hard carry case.

16. Applications: Environmental testing, Air conveyors, Flow hoods, Clean rooms, Air velocity, Air

balancing, Fans/motors/blowers, Furnace velocity, Refrigerated case, Paint spray booths.
