How long does the QBD1200 UV lamp last?
QBD1200 and lamp life
The UV lamp will typically last >12months, supporting an annual service and calibration interval. The UV lamp health is essential to the TOC analysis. The UV lamp is only turned on during the oxidation section of each water sample TOC analysis. The QBD1200 tests the UV lamp functionality on power on and this check can be initiated at any time by the user using the QBD1200 menu. In addition, the QBD1200 monitors the intensity of the UV light emitted every time it is switched on. If at any time the QBD1200 detects that the UV intensity is not strong enough, or that the UV lamp has failed to turn on when instructed to do so, then the QBD1200 stops trying to analyze the water samples and sets an alarm notification on the front screen.
