Hagner - Model TP200 - Digital Photometer Brochure

The Hagner Digital Photometer, model TP200, is a small, handy and extremely easy-to-use instrument for accurate measurement of illuminance. It has two ranges for measurement of both metric, lux (Ix) and imperial, footcandle (fc) units. The scales are chosen by setting the switch above the digital display. The sensitivity ranges are 0.1-200,000 Ix and 0.01-20,000 fc. With both automatic zeroing and on/off switch, the only controls needed are a four-position range selection switch and a hold button for retaining the display value.
