Description

The Linshang LS125 multi-probe UV light meter measures irradiance and accumulated energy using a detachable digital probe. Choose one of twelve probe kits for UVA, UVB, UVC or blue-light measurement. Each option supplies one LS125 main unit and one selected probe, with the probe response, aperture and measuring range matched to the light source being checked.

The host recognizes the connected probe and adjusts its displayed units and measurement interface. A 1mm aperture is available for LED point sources through the UVALED-X1 option. The UVCWP-X1 option provides a waterproof probe for immersion to 1m, while the main unit stays dry.

UVC-X0 230–280nm, 254nm peak. 0–200000 μW/cm². 10mm aperture.
UVCWP-X1 230–280nm, 254nm peak. 0–200000 μW/cm². 10mm aperture.
UVC-X2 210–250nm, 222nm peak. 0–200000 μW/cm². 10mm aperture.
UVCLED-X0 230–315nm, for 260–285nm LEDs. 0–200000 μW/cm². 10mm aperture.
UVB-X0 280–315nm, 310nm peak. 0–200000 μW/cm². 10mm aperture.
UVA-X0 315–400nm, 365nm peak. 0–2000 mW/cm². 10mm aperture.
UVA-X1 315–400nm, 365nm peak. 0–200000 μW/cm². 10mm aperture.

Irradiance, energy and response

The LCD displays real-time, maximum, minimum and average irradiance alongside duration and accumulated energy. UVA-X0, UVALED-X0, UVALED-X1 and BL-X0 sample at 2048 readings per second. The other listed probes sample at six readings per second.

For μW-range probes, accuracy is ±5μW/cm² below 50μW/cm² and ±10%H at or above that level. UVA-X0 uses ±0.5mW/cm² below 5mW/cm² and ±10%H at or above it. UVALED-X0, UVALED-X1 and BL-X0 use ±5mW/cm² below 50mW/cm² and ±10%H at or above it. H is the reference irradiance.

Measurement records and handling

Use HOLD to retain a completed reading and review saved records on the instrument. Select smoothing to suit AC-powered sources when using a high-speed probe. Keep the sensing surface clean and protect it from humidity during storage. UVCLED-X0 measurements require control of strong ambient light because of the probe's wider spectral response. Position the probe with appropriate UV exposure controls in place before energizing the source.
