Extech EA33 Easyview Light Meter with Memory

Elapsed Timer with Hold

In this mode, measurements are made while the countdown timer is running. When the timer reaches zero, the last measurement is held on the display

Stray Light Inhibit

This feature allows the user to measure light from one source while automatically factoring out the light from a secondary (stray) unwanted source.

Integral Illuminance Mode

Integral Illuminance is a luminous energy measurement based on the rate of flow of flux (expressed in lumen-seconds). The Model EA33 can also measure any photometric quantity on a time dependent basis. For example, the illuminance could be integrated over time to yield lux-hours (lx-h) or foot candle-hours (fc-h).
