DESCRIPTION:
The Extech EN510 10-in-1 Environmental Meter is a comprehensive handheld instrument designed for field and HVAC environmental measurements. It integrates a low-friction ball bearing mini vane wheel for accurate air velocity and airflow readings, precision sensors for humidity and temperature, and a photo diode for light level detection. The meter also calculates secondary parameters such as wet bulb, dew point, heat index, and wind chill. A Type K thermocouple input enables extended high-temperature surface measurements up to 2372 °F (1300 °C), and the large backlit dual LCD ensures readability in varied lighting conditions. Additional functions include data hold, MIN/MAX recording, and auto power-off with disable, making it suitable for HVAC testing, indoor air quality assessments, and environmental diagnostics.
