Bottle Wall Thickness Gauge

Bottle Wall Thickness Gauge

Background :

Uniform distribution of material across the walls of a plastic bottle is a key to achieving the best Top Load bearing capability. In order to check for the uniformity, usually people will cut the bottle open and then use standard micrometers.

Unfortunate the cutting process is both time consuming and poses a threat to the operator. The risk is much higher for glass bottles or jars.

The better method is to use a Wall Thickness Measurement device which does a non-destructive measurement of the wall thickness. This is a quick and safe method.

Applicable to : Generally Plastic or Glass Bottles and Jars. But can be used for other types of packages also.


Test Method :

There are 2 types of equipment :

  1. Magnetic Thickness Gauges which need a small steel ball to be placed inside the bottle and the probe outside. The ball gets attracted to the magnetic probe and uses the hall-effect principle to measure the distance between the ball and the probe. This is the most versatile equipment and doesnot need re-calibration for different substrates. The only limitation is that it cannot measure thickness of ferrous material.
  2. Ultrasonic Thickness Gauges which measures from outside only. The ultrasonic trans-receiver sends sound waves through the wall of the bottle and measures the time required for it to bounce back. Based on the known sound velocity of material, it can calculate the thickness. The limitation is that for every different material you wish to test, the unit’s calibration setting (a simple menu based setting) needs to be changed. The good point however is that these devices are considerably cheaper than magnetic thickness gauges.

More Details :


The Canneed “MBT-300 Hall Effect Thickness Gauge (Magnetic Bottle Thickness Gauge” is a refined portable bottle thickness gauge. It can measure the thickness of nonmagnetic material, such as plastic, glass, synthetics, aluminum and titanium, etc. The measurement accuracy is undistorted by the samples’ shapes.

MBT-300 is based on the theory of Hall Effect. For test, place the steel ball on one side of the sample and the probe on the other side. The Hall Effect sensor on the probe measures the distance from the probe tip to the steel ball. The device will display the real thickness readings.

●Adopt non-destructive test method. With quick measurement for spot thickness on area where accurate measurement of corners, small radii, or complex shapes are required
●Display the real thickness readings and automatically capture the minimum thickness
●A standard instrument in plastic packaging industry
●Rapid measurement, up to 16 times per second
●Accuracy: +/-1%
●It stores 95,000 thickness readings as the internal data record.

Technical Data:
Diameter of Steel Ball          Thickness Range (Standard Probe)       Calibration Graduation (Accuracy)
1/16″(1.59mm)                .0001-.0900″(.001-2.590mm)           +/-3%*
1/8″(3.18mm)                 .0001-.0900″(.001-4.570mm)           +/-2%*
3/16″(4.76mm)                .0001-.0900″(.001-6.350mm)           +/-1%*
