ALTA wireless light meters measure the intensity of light in lux (luminescence/unit area), from 0 – 83,000 lux (indoor range). Perfect for light sensitive applications like museum and art gallery light monitoring. User customization allows you to set the frequency of readings and the ability to set thresholds for notifications and alerts by SMS text, email or voice call from the system.
* Actual range may vary depending on environment.
** Battery life is determined by sensor reporting frequency and other variables.
