In addition to running all of the Q-SUN B02-compatible test standards, the Q-SUN Xe-2 tester can also run almost all other international weathering and lightfastness standards.  See the Xe-2 product page for more information.

Continuing with Q-Lab’s commitment to support our legacy testers in the field, Q-SUN B02 lamps, optical filters, replacement parts and expert troubleshooting and repair advice remain fully available to our valued customers around the world.

The Q-SUN B02 uses a single, 1800W air-cooled xenon arc lamp.  Air-cooling significantly reduces operating and maintenance expenses over water-cooled lamp devices.  Typical lamp life is 1500 hours.  Changing the B02 lamp is quick and easy – it is easily accessible from the top of the tester.  Replacement only requires the user to disconnect a simple plug connection, release two set screws, and remove the lamp housing.

Please use the following part number for replacement lamps:

• X-1850  Q-SUN B02 air cooled xenon arc lamp, 1800 W

The Q-SUN B02 optical filter lantern consists of an outer borosilicate cylinder and two sets of 7 durable inner filters, arranged in a two-tier heptagon.  For ISO and M&S standards, the inner filters are Window - IR (heat reducing).  For AATC TM16, the inner filters are Window - B/SL.

Please use the following part number for replacement optical filters: 

• XR-11234-K  Window-B/SL Filter Lantern (AATCC), includes 14 inner Window B/SL filters, and 1 borosilicate outer filter cylinder
• XR-11233-K  Window-IR Filter Lantern (ISO), includes 14 inner Window IR filters, and 1 borosilicate outer filter cylinder
• XR-11232-K  Window-IR inner filter replacement kit, 2 pieces

Easy Calibration Assures Accuracy
The Q-SUN B02 black panel temperature sensor needs to be calibrated periodically by the user.  This assures accurate and consistent results.

Calibrating the B02 black panel temperature sensor is simple using the Universal Calibrator system’s UC202 calibrated temperature sensor and UC1 handheld display, or the historical CT202 calibrated thermometer, and takes only a few minutes.  Note that the CT202 thermometer comes with either an uninsulated black panel (UC202/BP, CT202/BP) or insulated black panel (UC202/IBP, CT202/IBP) sensor.  This sensor must match the type of sensor actually used in the B02 tester.  The low-cost, combination relative humidity/chamber air temperature is designed to be replaced once a year and cannot be recalibrated.

Calibration of the UC202 and CT202 thermometers needs to be performed annually. The UC202 thermometers were designed to be disposable and cost-efficient, and should be replaced annually with a  freshly-calibrated UC202. The CT202 thermometer needs to be returned to Q-Lab once per year for an inexpensive recalibration. UC202 units may also be returned for calibration for users who prefer recalibration to replacement. See our Recalibration Return Procedure.  Our calibration labs are ISO 17025 accredited by the American Association of Laboratory Accreditation (A2LA - Ohio Certificate Number 2382-01, China Certificate Number 2383-02, and England Certificate Number 2383-03).  Calibrations are traceable to the U.S. National Institute of Standards and Technology (NIST).

Easy Calibration Assures Accuracy
The Q-SUN B02 SOLAR EYE irradiance sensor needs to be calibrated periodically by the user.  This assures accurate and consistent results.  Calibrating the B02 tester is simple using the Universal Calibrator system’s UC20 calibration radiometer or the legacy CR20 calibration radiometer, and takes only a few minutes.

Both UC20 and CR20 devices come with a 340nm, 420nm, or 300-400nm TUV (Total UV) sensor and must match the type of sensor actually used in the Q-SUN tester. CR20 calibration radiometers must also match the optical filter in use in the Q-SUN.

Calibration of the UC20 and CR20 radiometers needs to be performed annually. The UC20 sensors were designed to be disposable and cost-efficient, and should be replaced annually with a  freshly-calibrated UC20. The CR20 radiometer needs to be returned to Q-Lab once per year for an inexpensive recalibration. UC20 units may also be returned for calibration for users who prefer recalibration to replacement.  See our  Recalibration Return Procedure.  Our calibration labs are ISO17025 accredited by the American Association of Laboratory Accreditation (A2LA - Ohio Certificate Number 2382-01, China Certificate Number 2383-02, and England Certificate Number 2383-03).  Calibrations are traceable to the U.S. National Institute of Standards and Technology (NIST).

Specimen Mounting
The Q-SUN B02 tester supports 31 AATCC prepared samples in 16 holders, at 46 x 264 mm each. This equates to 1882 square centimeters of total specimen exposure area. The Q-SUN B02 tester's vertically mounted specimen holders are very easy to install and remove.  A variety of different ISO and AATCC textile masks and picture-frame holder kits are also available.
