Apogee UV-a Meter (Mu-250)

RUGGED, SELF-CLEANING HOUSING

Sensor features an anodized aluminum body with

fully-potted electronics. The dome-shaped sensor

head minimizes errors by shedding dust and water for

a self-cleaning performance.

CALIBRATION TRACEABILITY

Apogee UV-A series sensors are calibrated through

side-by-side comparison to the mean of four transfer

standard UV-A sensors under UV-enhanced T5

fluorescent tubes. The transfer standard UV sensors

are calibrated though side-by-side comparison to

an Apogee model PS-300 spectroradiometer under

sunlight (clear sky conditions) in Logan, Utah. The

PS-300 is calibrated with a quartz halogen lamp

traceable to the National Institute of Standards and

Technology (NIST).
