Oblique Screen Caliper

An oblique screen caliper, also known as a projection caliper, is a measuring instrument used to determine the internal or external dimensions of objects, particularly those with difficult-to-reach features or complex shapes. It relies on the principle of projecting an image of the measurement onto a screen for easier reading.

Material:

Typically constructed from hardened steel for durability and precision. The screen is often made of frosted glass or a similar material to provide a clear, readable projected image. More modern versions may utilize digital displays instead of a physical screen.

Purpose:

Designed for situations where direct reading with traditional calipers (vernier, dial, or digital) is impractical or impossible. This includes:

• Measuring internal grooves or holes.
• Measuring external features without directly contacting the object.
• Measuring parts with obstructions.
• Measuring parts that are difficult to access due to their location or shape.

Function:

The instrument projects a magnified image of the measurement onto a screen. The user aligns the caliper’s probes with the feature to be measured. The projected image is then read against a scale on the screen. The principle of projection allows for measurements to be taken without the direct physical contact of the measuring jaws with the object being measured, reducing the risk of damage to delicate surfaces.

Usage Scenarios:

• Tool and Die Making: Measuring complex internal features of dies and molds.
• Precision Engineering: Measuring the dimensions of small, intricate parts.
• Quality Control: Inspecting parts with hard-to-reach features.
• Medical Device Manufacturing: Measuring internal diameters of tubes or grooves in medical components.
• Automotive Industry: Measuring the dimensions of engine components.

Common Types:

• Optical Projection Calipers: Utilize an optical system to project the measurement onto the screen. These are typically more precise and are used for high-accuracy measurements.
• Digital Oblique Screen Calipers: Employ a digital display for reading the measurement, providing increased accuracy and ease of use. They often include features like zeroing, unit conversion, and data output.
• Internal/External Calipers: Some models are designed for both internal and external measurements, offering versatility.
• Specialized Calipers: Customized calipers are available for specific applications, such as measuring the dimensions of gears or splines.

Oblique screen calipers are measuring instruments used for length determination. Based on the provided reference material, the following HS codes may be relevant:

• 9017.30.40.00: This HS code covers drawing, marking-out or mathematical calculating instruments, and instruments for measuring length, specifically micrometers, calipers and gauges. The description explicitly includes micrometers and calipers. This is a strong match for oblique screen calipers, as they are a type of caliper.

  • 90: Chapter 90 covers measuring or checking instruments, appliances and machines.
  • 17: Heading 17 specifies drawing, marking-out, mathematical calculating instruments and measuring/checking instruments.
  • 30: Subheading 30 focuses on instruments for measuring length, including hand-held instruments like micrometers, calipers and gauges.
  • 40: Further specifies micrometers and calipers.
  • Tax Rate: Base tariff is 5.8%, with an additional tariff of 25.0%. After April 2, 2025, the additional tariff increases to 30.0%, resulting in a total tariff of 60.8%.

• 9017.30.80.00: This HS code also falls under drawing, marking-out or mathematical calculating instruments, and instruments for measuring length, specifically micrometers, calipers and gauges, but categorizes other types of micrometers and calipers. If the oblique screen caliper doesn't fit precisely into the 9017.30.40.00 category, this could be applicable.

  • 90: Chapter 90 covers measuring or checking instruments, appliances and machines.
  • 17: Heading 17 specifies drawing, marking-out, mathematical calculating instruments and measuring/checking instruments.
  • 30: Subheading 30 focuses on instruments for measuring length, including hand-held instruments like micrometers, calipers and gauges.
  • 80: Further specifies other types of micrometers and calipers.
  • Tax Rate: Base tariff is 3.9%, with an additional tariff of 25.0%. After April 2, 2025, the additional tariff increases to 30.0%, resulting in a total tariff of 58.9%.

• 9031.80.80.85: This HS code covers measuring or checking instruments, appliances and machines not specified elsewhere, specifically other instruments, appliances and machines. If the oblique screen caliper is considered a specialized instrument not clearly defined within the previous categories, this could be relevant.

  • 90: Chapter 90 covers measuring or checking instruments, appliances and machines.
  • 31: Heading 31 specifies measuring or checking instruments, appliances and machines not specified elsewhere.
  • 80: Subheading 80 focuses on other instruments, appliances and machines.
  • 85: Further specifies other types of instruments, appliances and machines.
  • Tax Rate: Base tariff is 0.0%, with an additional tariff of 0.0%. After April 2, 2025, the additional tariff increases to 30.0%, resulting in a total tariff of 30.0%.

It is important to note that the final HS code classification will depend on the specific characteristics and intended use of the oblique screen caliper.
