Maintenance Instructions: It is important to keep the caliper clean and dry to avoid any work malfunctions. If liquid enters the electronic system, it can cause damage. To clean the surface of the caliper, use soft cotton with a little petrol. Avoid using organic solvents such as alcohol or acetone. Do not use an electric pen to make marks as it can damage the caliper’s chip. Never apply any external force that can damage the caliper. If the caliper is not used for a long time, remove the battery to avoid leakage. Only use a CR2032 battery. Store the caliper in a dry and safe place at room temperature, away from direct sunlight and out of reach of children. Never use the caliper underwater.

IP54 Protection Grade: This Digital Caliper is equipped with an IP54 protection grade, providing protection against splash water from all sides and dust.

Extended Electrostatic Protection: The built-in chip in the caliper reacts quickly and up to 6 m/s, ensuring the accuracy and stability of measurements.

MM/Inch Switch Button: The digital caliper allows switching between metric and imperial units of measurement with the press of a button.

3V Battery & Auto-on/off Feature: This caliper uses a long-life CR2032 battery and features an auto-on function when the jaws are slid apart. It also has an auto-off feature that activates after 5 minutes of no use.

Large LCD Screen Display: The caliper has an extra large LCD display that shows instant and clear measuring data with digital numbers, making it easy to read. The buttons on the caliper provide a nice tactile feel and won't be accidentally activated.

Thickened Stainless Steel Ruler: Made of solid hardened stainless steel, this digital caliper resists corrosion and ensures smooth sliding and stable positioning.

Zero Switch Button: The caliper features a zero switch button that allows you to set the measurement to zero at any point, enabling you to start a new measurement.

Knurled Thumb Wheel: The knurled thumb wheel on the caliper slides smoothly for fine tuning and rolls easily without binding.

Locking Screw: The locking screw on the caliper is convenient and holds tightly, locking whatever reading you've taken.

Package Contents: - 1 × Digital Caliper - 1 × Hard Plastic Case - 1 × Spare CR2032 Battery - 1 × User Manual

Different Types of Measurements: - External Diameter: Measuring the outer diameter of objects with the long jaws. - Internal Diameter: Measuring the inner diameter of objects with the top jaws. - Step: Measuring the height/length with its step design. - Depth: Measuring the depth of hard-to-reach small objects with the long rod.

INDUSTRIAL GRADE: Unlike most calipers that use copper measuring sensors, our digital caliper adopts a glass material sensor, which effectively prevents the accuracy of the caliper from being affected by temperature, humidity, magnetism, etc. This greatly ensures the stability of measurement, allowing you to minimize errors and make high-precision measurements using our caliper measuring tool.

PRECISION AND ACCURACY: Our caliper allows you to measure thickness, width, or depth down to 0.001 inch. This level of precision is necessary for correct fitting and sealing. It enables you to create pieces that fit perfectly without any room for error. The measurement accuracy is 0.02mm/ 0.001 inch.

LONGER USEFUL LIFE: The housing of the caliper is composed of zinc alloy, and the ruler is made of first-class thickened stainless steel. The fine polish and new groove processing on the depthometer provide a more attractive and smoother slide, ensuring reliable results. The all-metal construction guarantees a longer lifespan for the caliper.

ZERO FUNCTION: The digital caliper allows for metric and inch conversions. It saves time during the measurement process. The smart design allows you to easily reset to zero by pressing the zero button and start a new measurement at any position on the scale, making it suitable for differential measurements.

EXTRA LARGE LCD SCREEN: With its extra-large LED screen, the caliper allows for easy and quick reading of measurements, even under strong sunlight or in dismal surroundings. The locking screws ensure that the measuring jaws are securely held, allowing for more precise measurements.

WIDE APPLICATION: This digital caliper is ideal for industrial and automotive, electrical, carpentry, carving, assembly, mechanical maintenance, professional, household measurement, and office work fields. We offer a 30-day money-back guarantee for any reason and a 12-month after-sales service for quality-related issues.
