UV Power Monitor F3UV
Monitor the Output of a UV Light Source
through an Optical Fiber Cable
Head Unit withstands temperatures of up to 300C.
Easy-to-read digital display of measurement values.
Harmful UV light converted to visible light before
performing measurements. This feature prevents
deterioration of the Amplifiers light receiving element.

Accessories Operation Manual
Note: 1. The response time is the rise time or fall time of the output signal to 10 to 90%.
2. The ambient operating illumination is the illumination that changes the analog output +5% F.S. at 200 lx; it is not the operational
limit.
3. An analog output of up to 6 V (or 24 mA) can be output. The output is 1 V (or 4 mA) when there is no incident UV light.
4. F.S. stands for full scale. For a current output, full scale is 16 mA (4 to 20 mA). For a voltage output, full scale is 4 V (1 to 5 V).
5. Definition of the luminous energy integral: The physical unit of the luminous energy integral is energy (J: joules) and this value
is calculated by multiplying the UV intensity (mV) by the time of exposure (s), but it is dimensionless when this sensors analog
output value (V) is used for the UV intensity. The integral is measured with an 11 ms sampling time.
