Calibrated levels are used in a wide range of applications and are built in a variety of forms to suit usage within those applications. Traditional mechanical levels utilize an air bubble floating within a substance (usually a mineral spirit) inside a vial which is attached to a flat surface. Reference marks on the vial represent the point at which the level surface is within an allowable tolerance. These models rely on gravity and a strictly visual interpretation of reading.
While mechanical levels are still widely used for quick reference of levelness in short increments, modern systems such as laser levels utilize a projected laser beam to determine levelness over greater distances. Some systems such as rotary laser levels even have the capability to project a beam over an entire plane.
J.A. King offers NIST traceable level calibration for all types of mechanical, electrical and/or electronic level indicating devices. Our team can certify levels using master standards such as granite surface plates and provide adjustments to ensure device zeros are correct.
