Multi-Measurement Software Option

The multi-measurement software option allows the 38DL PLUS to measure and
display the individual thickness of up to four layers of multilayer materials. You can
combine this function with the barrier layer thickness mode to measure the thickness
of barrier layers in multilayer plastic containers. You can save the measured values to
the internal datalogger or send them to a computer.
Multi-measurement common applications are:
• Multilayer plastic fuel tanks
• Multilayer plastic bottle preforms
• Multilayer aircraft windows
• Contact lenses: radius of curvature and thickness calculation
• Co-extruded plastic
• Two-layer hot tubs and spas
The 38DL PLUS has three different multi-measurement modes:
NORMAL
Measures and displays up to four different thickness layers or three layers and the
sum of any selected layers.
SOFT CONTACT
Displays sagittal height and lens thickness, and calculates the radius of curvature
of soft contact lenses. This mode is designed specifically for the measurement of
soft contact lenses.
% TOTAL THK
Displays the thickness of any layer as a percentage of the total thickness. Use this
mode for barrier layer measurement applications.
IMPORTANT
Before you can use the multi-measurement function with the NORMAL and the
% TOTAL THK modes, you must create and save a custom setup for each thickness
layer that you want to include in the multi-measurement. Refer to "Dual Element
