This hand-held radiometer is designed for testing germicidal lamps used in air-handling systems to verify their proper operation, especially in dirty and dusty environments that can adversely affect performance, the company says. The IL1470 Germicidal Radiometer measures the dose intensity of bacteria-killing UV lamps operating from 0.3 µW/sq cm to 15 mW/sq cm. Featuring a detector that automatically programs the instrument, the unit is self-prompting with pushbutton operation and provides direct readouts on its LCD display.
