The FT3425 is a light meter designed for an extensive range of applications involving illumination equipment, lighting work and facility management. Capable of testing even LED lighting, the FT3425 provides five measurement ranges, 20 lx to 200 000 lx, to support a wide range of luminance levels, and comes built in with Bluetooth® wireless technology.
How to Conduct Lighting Inspections: Using the Extension Cart to Easily Conduct Multi-point Tests
The FT3424 and FT3425 Lux Meters are supported by the Z5023 Extension Cart, which is built with casters to vastly improve the efficiency of making multi-point light inspections. When conducting final building inspections for proper illuminance, normally two inspectors are needed, and one is often required to stand and crouch repeatedly to capture the correct data. The Z5023 significantly saves both time and effort by enabling a single technician to do the job without the physical burdens.
Key Features
- Measured illuminance data is automatically sent to smartphone or tablet with Bluetooth® wireless technology
- Compatible with LED/OLED lighting
- Complies with DIN 5032-7:1985 class B and JIS C 1609-1:2006 general AA class
- Timer hold function lets you make measurements in remote locations while avoiding the effects of shadows and reflections
- Save up to 99 measured values in the instrument’s internal memory and transfer them to a computer later for improved work efficiency
- Data can be transferred to tablets and smartphones using Hioki’s dedicated free app "GENNECT Cross".
