Description

This ingenious device offers a practical and economical solution for light measurements in a variety of learning situations. Whether measuring environmental light or quantifying an optical experiment, this compact luxmeter meets the need. For most uses, the autoranging feature makes this a one-button-and-done instrument. Readings stabilize quickly. The auto power-off (after 5 minutes of no activity) conserves battery power, and for the times where more data is required, the MAX, MIN, HOLD, and difference functions are readily accessed. A threaded socket for tripod mounting is provided on the back of the case. Silicon diode sensor has a diameter of 2.5cm. Display size is 2.5cm x 2.5cm. Requires a 9V battery (not included). Almost 7 inches high.
