Data Logging Portable Luxmeter

The HD2102 luxmeters are handheld instruments with a large display capable of transferring data in real time to a PC or logging direct to its internal memory.

They measure illuminance, luminance, PAR, and irradiance using a wide variety of probes:

Photometric for illuminance and luminance.

Quantum radiometric for photon flow.

Radiometric for spectral ranges: UVA, UVB, UVC, and UV-BC

Radiometric for EFFECTIVE IRRADIANCE.

Combined Illuminance (lux) - Irradiance (W/m^2) - UVA spectral range.

Combined Total Effective Irradiance weighted according to the UV action curve

Global Solar Irradiance - pyranometer.

‍

In addition to the max, min, and average values it's also possible to measure the cumulative dosage over time integral Q(t).
