Electronic Digital Vernier Caliper

Product Code : SCL-AM-12111

The Electronic Digital Vernier Caliper is a high-precision measurement instrument used for calculating precise linear distances, internal/external diameters, and depth profiles in scientific laboratories. Designed for researchers, engineers, and students, this digital tool ensures rapid data collection with high dimensional accuracy.

Product Description

The Electronic Digital Vernier Caliper from Science Lab Supplies is engineered from hardened stainless steel to ensure high structural rigidity and corrosion resistance. The tool features an ultra-smooth sliding jaw mechanism that eliminates mechanical play, allowing for repeatable, micro-precise readouts. The integrated linear capacitive measuring system provides instantaneous values on a high-contrast liquid crystal display (LCD).

This versatile instrument optimizes instructional time by eliminating the reading errors commonly associated with traditional mechanical vernier scales. It allows students to focus entirely on experimental physics and data interpretation rather than troubleshooting scale alignment. This reliable digital tool is a standard staple across contemporary physics lab equipment inventories.

Key Features

• Hardened Stainless Steel Frame: The main body and measuring jaws are fabricated from high-grade steel to ensure long-term dimensional stability.
• Large LCD Display Screen: High-contrast display allows clear visibility of numerical figures, reducing eye strain in laboratory environments.
• Instant Unit Conversion: One-touch button switches the measurement readout seamlessly between millimeters and inches.
• Four-Way Measurement Capabilities: Precision-ground faces allow exact external, internal, depth, and step evaluations.
• Zero Calibration Button: Instant reset functionality enables easy relative or incremental differential measurements at any point along the beam.
• Thumb Roll and Locking Screw: Ergonomic fine-adjustment thumb roll allows controlled jaw movement, while the knurled locking screw holds data firmly in place.

Technical Specifications

What's Included in the Kit

• 1 x Electronic Digital Vernier Caliper 150mm
• 1 x Heavy-Duty Molded Storage Case
• 1 x Spare 1.5V LR44 Button Cell Battery

Applications / Uses

• Measuring the exact wall thickness and inner diameter of glass test tubes and volumetric beakers.
• Determining the precise dimensions of metal bars, wooden blocks, and solid spheres during classical mechanics labs.
• Calculating the accurate depth of drilled holes or internal steps inside prototype blocks.
• Integrating precise metrology standards into student-led science kits and robotics projects.
• Verifying structural material wear and calibration levels for other engineering components.

How to Use the Electronic Digital Vernier Caliper

1. Power On: Press the power button to activate the digital display screen.
2. Zero the Scale: Clean the measuring faces, close the jaws completely, and press the 'ZERO' button to calibrate the reference baseline.
3. Position the Jaws: Slide the jaw open using the thumb roll and place the object cleanly between the external measuring surfaces.
4. Lock and Read: Tighten the knurled locking screw gently to stabilize the position, then read the value directly from the screen.
5. Toggle Units: Press the mm/inch button if your experimental protocol requires data conversion.

Safety Note: Do not apply external electrical voltage to any part of the stainless steel beam, as electric currents will permanently damage the internal capacitive sensor assembly.

Care & Maintenance

• Keep Clean and Dry: Wipe the slider beam with a clean, lint-free cloth after use to prevent oil, water, or dust from disrupting sensor readings.
• Safe Storage: Always store the tool inside its molded protective case when not in use to avoid jaw misalignment from accidental drops.
• Battery Maintenance: Remove the button cell battery if the instrument will remain unused in the inventory drawer for more than six months.

Frequently Asked Questions

How accurate is the Electronic Digital Vernier Caliper?

The caliper features a high-precision resolution of 0.01 mm (0.0005 inches) and operates with an official accuracy tolerance of ±0.02 mm (±0.001 inches).

Can I switch between metric and imperial units instantly?

Yes, the integrated control panel includes a dedicated unit toggle button that instantly converts the active readout between millimeters and inches without resetting your position.

What type of battery does this digital caliper use?

The tool is powered by a standard, widely available 1.5V SR44 or LR44 button cell alkaline battery, and a replacement cell is included inside the box.

How do I measure the internal diameter of a tube?

You can insert the upper, smaller top jaws inside the opening of the tube, slide the thumb roll outward until the jaw edges meet the internal walls securely, and read the final value.

What should I do if the numbers on the screen start flashing?

Flashing numbers or a fading LCD screen typically indicate low battery voltage. Simply slide open the battery compartment cover and insert a fresh 1.5V battery cell.
