The MAVOMAX room light monitor is used wherever a constant illuminance has to be ensured. This applies, in particular, to compliance with the room classes according to DIN 6868-157 of diagnostic rooms, examination rooms with immediate diagnostics, dental diagnostic workstations and in teleradiology, where diagnostic monitors and light boxes for medical applications are used. For universally usable rooms with dimmable lighting, it supports the setting of the permissible illuminance for diagnostic.
No diagnostic monitor or film illuminator for medical applications per DIN 6856-1 is complete anymore without the MAVOMAX. It assures constant illumination and performs interior light monitoring for monitors in accordance with DIN EN IEC 61223-2-5 (QS-RL dated 20 Nov. 2003) and DIN V 6868-57. Monitoring ambient light extends the stipulated interval for constancy testing of image display devices for veiling luminance and maximum contrast to 6 months. In the case of periodic measurements within the framework of acceptance or constancy testing, veiling luminance need not be measured again, and the 60-minute waiting time until the image display device has reached a stable state is eliminated. Further applications include adherence to specified room conditions for dimmable lighting, as well as external workstations for emergency diagnostics.
A green LED indicates adherence to the permissible indoor light range for diagnostics, and a red LED indicates violation of this range.
Monitoring ambient light extends the stipulated interval for constancy testing of image display devices for veiling luminance and maximum contrast to 6 months. In the case of periodic measurements, there’s no need to repeat the veiling luminance measurement.
Two variants are available: one for general applications MAVOMAX 60 (20 to 60 lx), and one for use in the field of mammography MAVOMAX RK1 (10 to 50 lx) (corresponds to RK1 per draft standard DIN 6868-157).
Electrical power for the continuous operating mode is supplied to the meter by connecting it to a free USP port or the included mains power pack.
