Mangal instrumentation supplies CFL photometric and calorimetric instrument. It is used for testing several electric parameters like voltage, current, watt, power factor, factor, second voltage, frequency, etc. and luminous flux-lumen values, and calorimetric value of compact fluorescent lamps. It can be interlinked with computer by RS-232 port. The measurement of the correlated color temperature, luminous flux efficiency, etc are also done by the instrument. This instrument is very user friendly and provides reliable performance.
