Hot Wire AM-4204 Lutron is a anemometer with telescopic probe, that can measure gas flow rate in range 0.2 – 20.0 m/s and temperature in range 0 – 50C.
Features :
- Thermal anemometer, available for very low air velocity measurement.
- Slim probe, ideal for grilles & diffusers.
- Combination of hot wire and standard thermistor, deliver rapid and precise measurement even at low air velocity value.
- Microprocessor circuit assures maximum possible accuracy, provides special functions and features.
- Super large LCD with dual function meter’s display, read the air velocity & temp. at the same time.
- Heavy duty & compact housing case.
- Record maximum and minimum readings with recall.
- Data hold.
- The portable anemometer provides fast, accurate reading, with digital readability and the convenience of a remote probe separately.
- Multi-functions for air flow measurement : m/s, km/h, ft/min, knots. mile/h.
- Build in temperature C, F measurement.
- Thermistor sensor for temp. measurement, fast response time.
- Used the durable, long-lasting components, including a strong, light weight ABS-plastic housing case.
