Primary calibration: This involves comparing the instrument or equipment to a primary standard, which is a reference standard that is traceable to an international or national standard. Primary calibration is typically performed by a National Metrology Institute (NMI) or other accredited laboratory.
Secondary calibration: This involves comparing the instrument or equipment to a secondary standard, which is a reference standard that is traceable to a primary standard. Secondary calibration is typically performed by a laboratory or company that has been accredited by an NMI or other recognized organization.
On-site calibration: This involves performing calibration at the customer's location, rather than in a laboratory. On-site calibration can be more convenient for customers and can minimize downtime for equipment.
Field calibration: This involves performing calibration in the field or in an environment that simulates the conditions in which the instrument or equipment will be used. Field calibration can ensure that the instrument or equipment is calibrated for the specific conditions in which it will be used.
Routine calibration: This involves performing calibration at regular intervals, such as annually or semi-annually. Routine calibration can help to ensure that the instrument or equipment remains accurate and reliable over time.
