Testing: It is a verification process to find out the values of the different parameters involved to determine the quality of the commodity being traded or used by the different industries and the consumer worlds. Testing process gives the indication of the suitability of the commodity for usage or trading.
Calibration: Inspectorate is specialized in calibration of Vertical or Horizontal shore tanks, adopting such techniques as Laser Distance and Angles Technology with precise accuracy.

(EODR) Electro‐Optical Distance Ranging Method EODR Methodology ► Measurement of reference circumference by manual strapping method. ► Vertical measurement of tank shell by using electro‐optical distance ranging instrument. ► Bottom measurement by using horizontal auto level or laser level & leveling staff. ► Accurate measurement of positive, negative deadwoods, reference height & any other accessories that may
affect on tank working height & tank volume. ► Calibration chart calculations & preparation of calibration chart.
EODR Advantages ► More safe: The danger of falling from the ladders or Boson chair is eliminated.Vertical measurement of tank
shell by using electro‐optical distance ranging instrument. ► Less Cumbersome: The method eliminates any movement of heavy equipment such as hoists, boson chairs or
ladders. ► More Economical: Less persons are required during conventional strapping & ORLM vis a vis EODR method. ► More Accurate: Cancels out human random errors caused due to fatigue, environmental influences, improper
markings, Trolley movement at proper position etc.
