Lux meters are used to measure illuminance, and the FT3425 incorporates Bluetooth® wireless technology to enhance that core functionality. Used in combination with GENNECT Cross, Hioki’s free smartphone app, the instrument makes it easy to test illuminance, record results, and create reports, dramatically speeding up the measurement and reporting process.
The FT3425 can measure illuminance levels ranging from 0.00 lux to 200,000 lux. Consequently, it can be used to measure the low illuminance of emergency exit and evacuation signage as regulated by the Fire Service Act. In addition, the instrument can be used to measure lighting in healthcare facilities (examination and testing spaces as well as operating rooms) where high illuminance of around 100,000 lux is required. It can also be used to measure LED lighting, which has become increasingly common recently (more info).
