The SPR-104 is a versatile thermo anemometer designed to measure air velocity, air flow (volume), and temperature with precision and ease. Featuring a large backlit LCD with dual displays and multiple status indicators, it ensures accurate readings in HVAC, environmental monitoring, and industrial applications. With data hold, MAX/MIN/AVG recording, unit conversion functions, and the ability to store two area values for repeated CFM/CMM calculations, this instrument provides comprehensive airflow analysis in a portable, user-friendly package.
