dear Rishi,

frankly speaking , as per my knowledge  for shop use no instrument is there . but you can buy ready comparator in which different steel surfaces are available for different AARH values. you have to compare your product surface with that standerd prepared surface by hand and visual inspection and decide whether your product meet the required range or not. i am waiting for other experts view on this.

thanks

ansari.
