This combination supports reliable body fat percentage assessments with standardized increments and a durable construct for ongoing clinical or fitness applications.
Baseline 12-1116 Calibration Block Accessory
The Baseline calibration block accessory provides a compact reference for verifying a Baseline 12-1116 skinfold caliper. Its US origin and lightweight design support on-site checks and routine maintenance. Use this block to confirm consistent spring tension and dial response, ensuring readings stay within expected tolerances across measurement sessions and users.
YXQ Outside Micrometer Block 25mm/1inch
YXQ offers a stainless steel calibration rod suitable for outside micrometers and related tools. The block is designed for durability, low deformation, and easy portability. It serves as a general-purpose calibration reference when checking the accuracy of micrometer-based measurements, helping technicians maintain measurement integrity across workshops or field service calls.
HARFINGTON Standard Measuring Rod 25mm
The HARFINGTON rod is a 25mm outside micrometer standard with high precision (±0.001mm). Made from durable high-carbon steel, it is designed for long-term reliability in calibration routines. The universal rod format makes it suitable for various calipers and micrometers, providing a stable reference length to verify measurement consistency before and after use.
TMTECK Step Block 1018 Steel Calibration Block
This 1018 steel calibration block features five steps (0.1, 0.2, 0.3, 0.4, 0.5 inches) and a compact size. It comes with a carrying case and a certificate, making it suitable for calibrating calipers and verifying thickness measurements across a spectrum of ranges. The block’s robust steel construction supports repeatable results in professional environments.
25mm Calibration Bar for Micrometers
The 25mm calibration bar provides a stainless steel reference for micrometers and caliper checks. Its robust construction and multiple specification options support accurate calibration across a range of measurements. This block is designed to resist deformation and maintain calibration over repeated use in workshop conditions.
Buying Guide: Key Purchase Considerations
Calibration blocks vary in material, step configuration, and compatibility. When selecting blocks for calipers, consider the following:
- Measurement range: Ensure blocks cover your instrument’s typical thickness or width readings, including common steps such as 0.1″ to 0.5″ or 10–50 mm for Lange or generic calipers.
- Material and precision: Stainless steel and high-carbon steel blocks offer durability and stable readings. Look for accuracy ratings and standard tolerances (e.g., ±0.001 mm).
- Block configuration: Choose blocks with multiple steps for quick calibration checks, or single/dual blocks for focused validation. Skinfold-specific sets can include complementary charts and case protection.
- Case and portability: A carrying case helps protect the block and keeps calibration documents organized, particularly for fieldwork.
- Certification and documentation: Factory certificates or calibration documentation can be important for clinical or regulatory environments.
- Brand reliability and compatibility: Select blocks from reputable brands with stated compatibility for your caliper models to avoid mismatches.
In practice, a combination approach works well: a multi-step block for broad checks, a stable micrometer rod for general calibration, and a skinfold-specific block set where body composition measurements are routine. Regular calibration against your blocks helps maintain measurement integrity, reduce drift, and support consistent data across operators and sessions.
