Dear Mr. Rahul,
Our engineer is continuously following up for restoring SO2 analyzer but still we are awaiting your action plan to restore it.
As per your follow up with local party IMI, their engineer visited two weeks back but he could not restore/repair it and said need mother board to replace. It also seems that local service engineer not have sufficient skill and knowledge on this MIR9000. Please look in this matter on urgent basis as you very well aware of environmental related legal issues here.
