The QUV UV Aging Test Chamber lamps have been upgraded with the new UVA-340+ and UVB-313EL+ lamps having a higher irradiance output than the standard UVA-340 and UVB-313EL lamps.
UV ultraviolet aging test chamber new lamps in high irradiance (155 W m2 nm) and a maximum irradiance of 750 hours (170 W m2 nm). Standard UVA-340 and UVB-313EL lamps continue to play an important role. At typical irradiance levels, they have a lifetime of 8000 hours. They do not guarantee high or maximum irradiance values.
In order to ensure that the lamp service life can be longer at high irradiance.
The spectral distribution of the UVA-340+ lamp is the same as that of the UVA-340 lamp.
All CR10 calibration radiometers and UC1 handheld displays with the UC10 UV Smart Sensor can correctly calibrate the UVA-340 and UVA-340+ lamps.
Users with irradiance control testers (QUV SE, QUV SPRAY, QUV SPRAY RP) should use the UVA-340+ lamp and its results should not be altered.
Users using the QUV Basic tester may get more severe results with the UVA-340+ lamp. These users have a limited number of UVA-340 lamps**.
The spectral distribution of UVB-313EL+ lamps is slightly different from that of UVB-313EL lamps.
The CR10 calibration radiometer cannot be used to properly calibrate UVB-313EL+ lamps. CR10 users must upgrade to a universal calibrator system to use the UVB-313EL+ lamp.
The UC1 handheld monitor software must be updated to 1040 or later so that the option to calibrate the "UVB-313EL+" lamp is available. This update is required for accurate calibration of UVB-313EL+ lamps.
Use irradiance control testers (QUV SE, QUV SPRAY, QUV SPRAY RP) to control the use of irradiance control testers at high irradiance (155 W m2 nm) should use the UVB-313EL+ lamp.
Typical irradiance (071 W m2 nm) and users using the QUV Basic tester should continue to use the UVB-313EL lamp.
Users with these testers may get more serious results with the UVB-313EL+ lamp. These users can still use the UVB-313EL lamp for a long time.
