LP471UVBC – UV-BC Irradiance Probe

Senseca — Fri, 05 Mar 2021 11:24:48 +0000

LP471UVBC is a radiometric probe for measuring irradiance (W/m²) in the 210…355 nm spectral range with peak at 265 nm. It is equipped with a connector with SICRAM module and a 2 m cable

The probe consists of a photodiode with an appropriate filter and is provided with a diffuser for correct measurement according to the cosine law. It is typically used in the verification of germicidal lamps used in sterilization systems working with LEDs as UV light sources.

The probe is available as well already combined in ready to use kits. Dependig on your needs, you can choose a basic one composed by the probe and our HD2302.0 luxmeter to simply measure and read the values (UVBC-CK02-ACC). For a more advanced version with data logging feature, the probe is combined with our HD2102.2 portable luxmeter datalogger (UVBC-CK01-ACC).

For both solutions, the correctness of your measurements are also assured by the ISO 17025 Calibration Certificate issued in our own accredited Photo-radiometry laboratory.

LPPAR01 – Photosynthetically Active Radiation Probe

The LPPAR01 probe measures the ratio between the number of photons that strike a surfacein one second, in the 400 nm…700 nm spectral range and the surface area (m²). This quantity is defined as PAR: Photosynthetically Active Radiation.

The probe calibration is carried out by using an halogen lamp, with a known spectral irradiance in a specific spectral range. Temperature slightly affects the probe spectral response.

The diffuser and the probe particular structure, allow the response to the variation of the light incidence angle on the diffuser, to be cosine corrected.

The LPRAD01 probe measures irradiance (W/m²) defined as the ratio between the radiantflux (W) passing through a surface and the surface area (m²) in the VIS-NIR (400 nm…1050 nm) spectral range.

These particular features apply to an instrument suitable for measurements invisible and near infrared fields.

Probe calibration is carried out by using 577 and 579 nm lines of a Xe-Hg lamp, filtered through a special interferential filter.
