The 3253 Light Meter has a UV wavelength range of 320 to 390 nm. It measures on three different ranges from 0 to 199.9 µW/cm2 (resolution 0.1 µW/cm2), 1.999 mW/cm2 (resolution 0.001 mW/cm2), and 19.99 mW/cm2 (resolution 0.01 mW/cm2). Accuracy is ±(2% of full scale plus 2 digits).

Connect to computer or data logger
The 3253 Light Meter has a serial RS-232 output that allows it to be connected to a computer or data logger for monitoring and keeping results.

Cosine- and color-correct measurements
Unit recalls highest, lowest, and average readings at the touch of a button. DATA HOLD button freezes the display to capture readings. Precise photodiode and color-correction filter provide cosine- and color-corrected measurements.
