RM-12 radiometer: inexpensive measurement of irradiance and illuminance
The radiometer RM-12 is a battery-powered hand-held instrument for measuring irradiance and illuminance. The measuring range covers 0–199 mW/cm², optionally 0–1999 mW/cm², at a resolution of 0.01 mW/cm²; illuminance is recorded up to 200,000 lx. Through the M12 connector, sensors for spectral ranges from UVC to VIS can be exchanged, and a 9 V battery lasts for about 50 operating hours.
Due to the sensor-integrated electronics, different sensors for UV and visible spectral ranges can be measured with the respective sensors. Sensors evaluating biological effects of irradiation are also available.
The integrated diffuser serves to provide the cosine correction that is necessary with non-perpendicular irradiation. The sensors are calibrated with traceability to the PTB; after being calibrated, they are supplied with a factory calibration certificate. Repair and spare parts service is, of course, available for many years.
The sensors can be supplied with different measuring ranges.
Applications:
- Measurement of UV lamps, UV LEDs, and light sources
- Control of UV irradiation
- Photometric measurements
