The only Flicker meter I've found is a mains voltage monitor - not very
good.

 

The only thing we can think of is a calibrated strobe lamp that you can
shine on the flickering object and vary the rate of flashes - but it
would need to be calibrated pretty accurately.

 

Difficult one.

Subject: Screen Flicker Test

 

Hi All,

Please forgive me if this question has been asked numerous times.  Does
anyone know a way to test an object to determine if it flickers between
2 and 55 Hz?  I saw somewhere that you could use a stop watch but I
can't imagine someone being able to count 55 times in a second.  

Thanks in advance,

Scott
