Hour Meter

Most UV systems have an hour meter that allows you to track (with a little subtraction) the number of hours on the current bulb in the lamp housing. This number is worth tracking over time and you may be able to draw general conclusions or use it to drive your preventative maintenance programs but keep in mind that the information it provides will only give you an estimate of bulb life. The hour meter does not indicate the operating conditions in which the bulb was run or the condition of the reflectors. The hour meter also does not indicate the amount of UV reaching the cure surface.
