Angle indicators and protractors, also known as, clinometers or inclinometers are used in a wide range of applications to measure angle or slope of an object. Similar to levels, angle indicators typically come in mechanical and digital models for usage based on application requirements. For the most part, both types rely on a secondary metric such as gravity force as a reference for determining a measurement.

Many traditional mechanical angle indicators similar to mechanical levels, utilize a liquid substance within a disk-shaped vial which is attached to a flat surface. Reference marks on the vial represent the corresponding angle at which the flat surface rests. These models usually rely on a strictly visual interpretation of scale.

Electronic models are typically capable of higher accuracy, simply due to digital interpretation. They usually utilize either pendulum style mechanics, or multi-axis sensors which relay a digital reading. Some of these highly accurate angle indicators are capable of producing up to a 0.0001° output resolution.

J.A. King offers NIST traceable calibration for all types of mechanical, and electrical angle indicating devices such as fixed protractors, bevel protractors, digital protractors, clinometers or inclinometers. Our technicians utilize master standards such as surface plates, angle blocks, and sine bars, among others, to perform a comprehensive calibration including readings at a minimum of four test points.

In addition, our team can provide as found, as left readings on a certificate of calibration which your quality team can access 24/7 using GageSuite™, our online calibration certificate tracking system.
