Hioki Launches JIS Class AA and DIN Class B-compliant Illuminance Meter FT3424

Hioki E.E. Corporation is pleased to announce the launch of the Illuminance Meter FT3424. Illuminance meters are used to measure the brightness of light sources. Illuminance is defined by JIS and other standards, and the FT3424 complies with general classes AA and A as set forth in JIS C 1609-1:2006 and Class B devices under DIN 5032-7.

The FT3424 is capable of measuring a broad range of illuminance values, enabling its use in testing targets ranging from emergency and guidance lighting in buildings to lighting in healthcare and medical facilities such as operating rooms. It can also measure LED lighting, which has been growing in popularity recently.

1. Compliance with general classes AA and A of JIS C 1609-1:2006

The FT3424 complies with general classes AA and A as defined by the JIS standards, making it suitable for use as a general-use illuminance meter. Class AA: Instruments that are used in illuminance measurement in lighting locations where illuminance values are required to exhibit a certain degree of reliability, for example in evaluating compliance with standards and rules

2. Broad measurement range, from low to high illuminance (0.00 to 200,000 lux)

Measure low illuminance levels such as those of emergency and guidance lighting as required by the Fire Service Act. It can also be used to make measurements in healthcare and medical facilities where high illuminance levels of around 100,000 lux are required (examination and testing spaces, operating rooms, etc.). The instrument can also be used to measure LED lighting, which has been growing in popularity recently.

3. Timer hold function to keep worker clothing or shadows from affecting measurement results

When measuring the illuminance of emergency or guidance lighting, the possibility exists that readings may be influenced by workers'' clothing or shadows. The FT3424 addresses this issue with a new timer hold function that fixes the measured value after a preset amount of time has elapsed when the TIMER key is pressed. This delay gives workers enough time to move away from the illuminance meter, eliminating the need to worry about workers affecting measurements.

4. Save up to 99 values in internal memory

The FT3424 provides new capability for saving up to 99 values in its internal memory. This functionality is extremely convenient when measuring multiple classroom locations to establish compliance with school environmental hygiene standards.
