Light and radiation checks often move between benches, installations and field locations. This portable photo-radiometer gives technicians one handheld instrument for illuminance, luminance, PAR and irradiance measurements, including VIS-NIR, UVA, UVB, UVC and effective UV irradiance according to the UV action curve.
Setup stays simple when tasks change. Compatible LP471 probes use SICRAM automatic detection, with factory calibration data stored in the probe and automatic unit selection by the instrument. The large LCD supports clear on-site reading, while Max, Min, Avg, REL and HOLD functions help capture changing light conditions without extra equipment.
Built for portable work, the instrument combines IP67 ingress protection with an ABS housing, 140 x 88 x 38 mm dimensions and a weight of 160 g with batteries. It operates from 5…50 °C and runs for up to 200 hours on 3 AA alkaline batteries, making it a practical choice for repeated photometric and radiometric measurements.
The instrument measures illuminance, luminance, PAR and irradiance. Depending on the connected probe, it works with lux, fcd, W/m², µW/cm², µmol/(m²⋅s), cd/m² and µW/lumen.
The 8-pole DIN45326 input connects LP471 photometric, radiometric, PAR, pyranometer and combined probes with SICRAM modules. The probe must be connected before the instrument is switched on.
The keyboard provides Max, Min and Avg calculation, REL relative measurement and HOLD value freeze. The CLR key resets captured maximum, minimum and average values for a new session.
The instrument assigns the measurement unit according to the connected probe. With combined probes, the UNIT key selects the available measured quantity shown on the display.
The instrument uses 3 1.5V AA batteries. AutoPowerOff switches the device off after about 8 minutes without key input and can be disabled when continuous operation is required.
The housing is made from ABS and has IP67 ingress protection. The instrument operates at 5…50 °C and 0…90% RH without condensation, with storage from -25…+65 °C.
