The Hioki FT3424 Lux Meter is engineered to provide accurate and reliable illuminance measurements across a wide range of lighting conditions. With its five selectable measurement ranges—20 lx, 200 lx, 2,000 lx, 20,000 lx, and 200,000 lx—it caters to both low and high illuminance scenarios. The device utilizes a silicon photodiode as the light-receiving element and features a large, easy-to-read LCD display with a backlight that activates automatically in low-illuminance environments. A standout feature of the FT3424 is its timer hold function, which allows users to make measurements in remote locations while minimizing the effects of shadows and reflections. Users can select timer settings ranging from 5 to 60 seconds, with the remaining time displayed on the screen. Once the set time has elapsed, the measured value is retained, and the backlight turns on if the illuminance is less than or equal to 10 lx. The FT3424’s internal memory can store up to 99 measured values, facilitating multipoint measurements. These stored values can be transferred to a computer via a USB connection for further analysis and reporting. The device is compatible with Windows operating systems, including Windows 7, Vista (SP1 or later), and XP (SP2 or later). Designed for durability, the FT3424 complies with DIN 5032-7:1985 class B and JIS C 1609-1:2006 general AA class standards, ensuring optimal reliability. Its compact and lightweight design, weighing approximately 310 g, makes it easy to handle and transport. The device is also dustproof and waterproof with an IP40 rating, suitable for indoor use in environments with pollution degree 2 and altitudes up to 2,000 meters.
