I was found that temperature of some accumulator is lower than other. Cause maybe come from either low pressure of N2 or bladder broken.

There is a multitude of items that you can see in verying degrees of breakdown with infrared in hydraulic systems. Pumps in failure mode will be hot and you can see the temperature of the pressure lines change rapidly as the load changes. You can see "blow-by" on the outside walls of cylinders, indicating where the seals are deteriorating, these as warm or hot spots. You already have a good example of accumulators by L.Weerawut. You may even be able to find leaks by searching for warm traces in pooled oil and/or running down support structures since system oil is warmer than the maching exterior. Good luck!

Dear Mr. Weerawut and Top Gun,
Thank you for this valuable information that I will now for sure practice.

Kind regards/PO.Eliasson

While IR is a great aid, you must take into account it is still just that an aid, to be totally sure of the problem the system, it needs to have some basic mechanical checks to be done to back up your findings, start with the simple ones, is the isolation valve closed on the bottom of the bottle? this would stop the warm oil entering the bottle?
