UV Power Monitor/Sensor
UV-300K

Ideal for continuous monitoring of output state of UV
UV sensor picks up and displays the ultraviolet rays that eye is unable to perceive. It is a device used for continuous monitoring of UV light intensity. Since SUMITA’s ultraviolet to visible wavelength conversion glass is used in UV-300K, its reliability is high, and it is an optimum sensor device for line inspection in production process. UV-300K enables detecting UV lamp’s deterioration and lighting failure.

SUMITA’s UV sensor/monitor UV-300K features:

Highly durable glasses are used for converting ultraviolet to visible light wavelength
Monitoring wavelength range: 170- 380 nm
Feedback UV lamp’s light intensity variance
Two operating modes provided: light intensity mode and integration mode
Analog voltage output: voltage (1 - 5 V) and current ( 4 – 30 mA)
Sensitivity setting by teaching
Answer-back output function
The optimum sensor head selectable for the wavelength employed
Simple operation
