Advanced Light Meter
Featured Rental
Automatically compensating for different types of lighting, our sper scientific light meter rental instruments remove the need to use correction factors and provide true results in real time. With a large range of measurement over 5 user selectable ranges, a quick zeroing procedure, and many other advanced features, the 840022 makes quick work of any light monitoring task. Readings are displayed on a large LCD display both numerically and as a bargraph in either lux or foot candles. The sensor features a quick response, high resolution, and is both cosine and color corrected. A RS232 interface provides a digital output or connection to datalogging systems and PCs.
