The easiest and fastest way is to use the DPD indicator. If chlorine is present you will observe a pink coloration.

For instant checking of chlorine in field chlototex reagent is the best.

For Laboratory accurate checking DPD method with the hep of photometer is best.

And apart from above method one can always check the chlorine level by comparig it with ORP reading.
