Product catalog summary

Overview: This document provides technical specifications and details for various optical radiation probes designed for measuring different types of radiation, including illuminance, UVA, UVB, UVC, global radiation, IR, and quantum radiation. These probes are equipped with ALMEMO® connecting cables and are suitable for indoor applications.

General Specifications:

Probes are housed in sturdy aluminum with a black anodized finish.
Operating temperature ranges from -20 to +60 °C.
Signal output is 0 to +2 V with a duty cycle of less than 1 second.
Power supply is via ALMEMO® connector (5 to 15 VDC).

Illuminance Probe (FLA 623 VL):

Measures V lambda radiation, equivalent to human eye sensitivity.
Used for evaluating lighting conditions in workplaces.
Complies with device class B as per DIN 5032.
Measuring range: 0.05 to approx. 170 klx.
Spectral sensitivity: 380 to 720 nm, max. at 555 nm.

UVA Radiation Probe (FLA 623 UVA):

Measures long-wave UV radiation with a bronzing effect on skin.
Spectral sensitivity: 310 to 400 nm, max. at 355 nm.
Measuring range: 0.03 to approx. 100 W/m².

UVB Radiation Probe (FLA 623 UVB):

Measures short-wave UVB radiation, likely to cause erythema.
Spectral sensitivity: 265 to 315 nm, max. at 297 nm.
Measuring range: 0.002 to approx. 5 W/m².

UVC Radiation Probe (FLA 623 UVC):

Measures UVC radiation, used in water disinfection units.
Spectral sensitivity: 220 to 280 nm, max. at 265 nm.
Measuring range: 1 to approx. 1990 mW/m².

Global Radiation Probe (FLA 623 GS):

Measures solar spectrum in visible and short-wave IR range.
Spectral sensitivity: 400 to 1100 nm, max. at 780 nm.
Measuring range: 0.4 to approx. 1300 W/m².

Infra-red Radiation Probe (FLA 623 IR):

Measures solar spectrum in short-wave IR range.
Spectral sensitivity: 800 to 1100 nm, max. at 950 nm.
Measuring range: 0.1 to approx. 400 W/m².

Quantum Radiation Probe (FLA 623 PS):

Measures visible light absorbed by chlorophyll during photosynthesis.
Spectral sensitivity: 380 to 720 nm, max. at 420 and 700 nm.
Measuring range: 1 to approx. 3000 mmol/m²s.

Options: Each probe variant is available with ALMEMO® connecting cables of different lengths (2, 5, and 10 meters).
