Digital Caliper Manufacturer,Supplier and Exporter in India
Product Code : EL-AELE-12911
Jlab Export is a leading Digital Caliper Manufacturer,and suppliers in India
A digital caliper shows each size as a number on its display, so no scale lines have to be matched by eye. This one measures from 0 to 150 mm and takes outside, inside, depth and step readings. It switches between millimetres and inches and turns itself off after 5 minutes with no operation.

Measuring Practicals for Workshop Students
In a fitting or RAC workshop, students measure the outside diameter of Copper Pipe and the bore of a socket made with the Tube Expander. The depth rod shows how deep the socket goes, and the step faces measure a shoulder on a turned part.
For a comparison exercise, students measure the same five parts with this caliper and with a Dial Caliper, then list the readings side by side. Teachers can switch the display to inches and have students identify imperial tube sizes, such as 1/4 in and 3/8 in refrigeration tube.
Frequently Asked Questions
How do I set zero on the digital caliper?
Wipe the jaw faces, close them gently and set the display to zero with the jaws shut. Check the zero again before each new set of readings and whenever you change from millimetres to inches.
What can it measure?
The main jaws take outside sizes and the inside jaws take bores. The depth rod measures holes and slots, and the step faces at the head of the slider measure shoulders. Each reading appears directly on the display.
Why does the display turn off by itself?
It saves power. The caliper switches off after 5 minutes with no operation, so it is not left running in a drawer. If the reading has moved when you switch it back on, close the jaws and set zero again.
Is a digital or a vernier caliper better for a student lab?
A digital caliper is quick to read and switches to inches. A vernier caliper needs no power and teaches students how a scale is read. Many labs keep both, for example this caliper and the Analogue Caliper.
Why do two people get different readings on the same part?
Each person presses the jaws with a different force and sets them at a slightly different spot. Dirt on the faces and a part still warm from machining add more spread. Clean the faces, set zero and measure with light, even pressure.
