Delta OHM LP471A - Uveff ? Total Effective Irradiance Probe

The combined probe LP471A-UVeff measures the Total Effective Irradiance (W/m²) weighted according to the UV action curve (CEI EN 60335-2-27).

The probe is made of two sensors, the signals of the sensors are combined and weighted to obtain an accurate spectral response. The two probes are equipped with a diffuser for the correct measure according to the cosine law.

The probe provides the following data:

• Total Effective Irradiance (E_eff) – Measuring range: 0.01 W/m²…20 W/m².
• Effective Irradiance in the range UV-CB – Measuring range: 0.01 W/m²…20 W/m²
• Irradiance in the UVA spectrum – Measuring range: 0.1 W/m²…2000 W/m²

When used for the control of cosmetic tanning systems, with the LP471A-UVeff  it is easy to determine the exposure time for the first session (set to  100J/m² effective) and the total time per year (maximum dose limit established is 15kJ/m² per year). Alternatively you can calculate the dose received per session. You can also check the status of lamps aging by regularly measuring the solarium emission.
