A groundbreaking illuminance meter with high precision at an innovative price.
The LPPHOT02 series illuminance meter measures illuminance (lux), defined as the ratio of luminous flux (lumens) incident on a surface to unit area (m²). The spectral response curve of the photometric measurement probe approximates the human eye's response curve, known as the standard photopic curve V(λ). The difference between the LPPHOT02 series and the standard photopic curve V(λ) in spectral response is calculated as error f’₁. The LPPHOT02 series illuminance meter has a robust structure, designed for long-term outdoor use, and is primarily used for meteorological measurements in daylight.
Handheld high-precision illuminance, luminance, and radiance meter equipped with a large LCD.
■ Measures illuminance, luminance, PAR (photosynthetically active radiation), and irradiance (in the spectral ranges of VIS-NIR, UVA, UVB, UVC, UVBC, or effective radiation according to the CIE UV action curve) based on the selected probe. ■ All probes are equipped with the automatic recognition module "SICRAM." ■ Automatically selects not only the type of connected probe but also the measurement units. ■ Displays maximum, minimum, and average values over any specified time using the MAX-MIN-AVG function. ■ Equipped with a REL (deviation measurement) function that displays deviations (positive or negative values) based on measurements at any moment, a HOLD function, and a user-releasable auto power-off feature. ■ Features a rubber exterior on the main body perimeter and connector area. ■ Protection rating IP67. ▼ Illuminance, luminance, PAR, UVA, UVB, UVC, UVBC, illuminance + UVA, blue light, solar radiation. ▼ MAX-MIN-AVG, deviation measurement. ▼ Large LCD display.
Spectroradiometer with data logger function
■A measuring device developed for spectral analysis of visible and ultraviolet light, equipped with data logger functionality. ■Designed with flexibility of use, cost, and ease of use in mind. ■Consists of a display unit with built-in data logger functionality [HD30.1] and two types of measuring sensors: [HD30.S1] (spectral range 380–780nm) and [HD30.S2] (spectral range 220–400nm). ▲Probe HD30.S1 (visible light) and HD30.S2 (ultraviolet light). ▲Measurement execution, value confirmation, and saving possible with a large touch panel. ▲Data storage with built-in memory and external memory (microSD, USB). ▲Data export in Excel-compatible format.
