The SPR-108 Thermo-Anemometer is a portable device designed for measuring air velocity, temperature, and humidity using an impeller-type sensor. It features a clear LCD display, multiple unit conversions, and practical functions like MAX/MIN/AVG recording and data hold. Ideal for HVAC, environmental monitoring, and industrial applications.
- Measures air velocity (0.4–30 m/s), temperature (-10°C to 60°C), and humidity (0–100% RH)
- Multi-unit support: m/s, ft/min, km/h, mph, knots, CFM, CMM
- Data functions: MAX/MIN/AVG recording, data hold, backlight
- Auto power-off after 15 minutes (adjustable)
- Low battery indicator and replaceable 9V battery
- User-friendly interface with setup options for area and unit preferences
