To succeed in your field, you need equipment for precise measurement. It is necessary to choose an equipment that offers precise precision and repeatability when measuring internal dimensions. These things are met by the Mitutoyo Digimatic Holtest. It gives you the confidence to measure holes and bores with a range of ranges. Its digital display provides precise measuring with readings down to 0.001mm. Equip yourself with the Mitutoyo Digimatic Holtest’s exacting measuring capabilities to achieve optimal results in your work. Allow this excellent internal micrometre to become a vital weapon in your arsenal as you strive for project precision.

What Are Digital Holtest Instruments?

The digital holtest is a very accurate measuring tool for measuring internal diameters. It  is made up of a spindle, anvil, ratchet thimble, and digital display. The workpiece’s hole or cavity is where the anvil and spindle are placed. The spindle travels inward and outward when the ratchet thimble is rotated. With a resolution of 0.001mm, the digital measurement of this extension is shown on the LCD screen in microns.

Range and Accuracy

With a resolution of ±1 μm, the Mitutoyo Digimatic Holtest Internal Micrometre is capable of measuring a wide range. It is appropriate for measuring bores, holes, and cavities in components where extreme precision is needed because of its range and accuracy. Light, constant pressure may be applied thanks to the ratchet stop mechanism, which also helps to avoid overtightening.

Data Output and Interface

The measured values can be seen in metric units on a digital LCD panel. Additionally, the instrument contains a data output connection that, when used with an extra cable, enables the transfer of measured information to a computer. On the transferred data, statistical computations including mean, maximum, and minimum values can be carried out.

Durability and Portability

The Holtest device is built with strength and durability. Its small size, low weight, and portability make it ideal for usage in tool rooms, machine shops, and production floors. When not in use, the instrument can be stored in its protective case. The Holtest can yield many years’ worth of precise measurements with regular calibration and adequate maintenance.

Why are digital holtests important for construction and engineering industries?

In order to maintain quality standards and meet requirements in a variety of applications, accurate measurements are crucial, which is why the digital holtest is so important in the engineering and construction sectors. 


In engineering and building projects, accuracy is crucial. Because of the excellent accuracy of the digital holtest, internal dimensions may be measured with remarkable precision, ensuring that structures and components fit precisely. For jobs like part machining, making sure assemblies are aligned correctly, and meeting tight tolerances, precision is essential.


Within any industry, time is a valuable resource. The digital holtest simplifies measurement procedures, which increases efficiency. Its accurate measurements and easy-to-use interface shorten the time needed to evaluate internal dimensions. Project timeframes are aided by this efficiency, which results in quicker manufacturing cycles.

Quality Control

In the engineering and construction industries, upholding quality standards is essential. The Digital Holtest is a vital instrument for quality control since it guarantees that products fulfil both customer and regulatory standards. It helps detect deviations from specifications early in the production or building process, avoiding expensive rework and guaranteeing constant quality by offering precise measurements.


Because of its adaptability, the digital holtest is a useful tool for a variety of engineering and construction activities. Its versatility renders it indispensable in a wide range of applications, whether it is measuring bore diameters, confirming hole depths, or evaluating interior dimensions of different components. The Digital Holtest is a versatile asset in any workshop or production setting, accommodating a wide range of measurement needs from structural fabrication to precision machining.

Data Management

Effective data management is crucial for making well-informed decisions in the current digital era. The data output port on the digital holtest enables smooth computer system integration, promoting effective data administration and transfer. It is simple to capture, examine, and store measured values for later use. The transferred data can be used to perform statistical computations, such as mean, maximum, and lowest values, which can offer important insights into process performance and quality trends.

Cost-Effective Solution

The Mitutoyo Digimatic Holtest Internal Micrometre is reasonably priced despite its great accuracy. Compared to similar products, its robust, industrial-grade structure and digital features offer value at a lesser cost. Its performance and cost-effectiveness make it the perfect choice for quality assurance and production optimisation for a lot of manufacturers.

Check Points for Digital Holtests

Before Use:

  • Make sure all surfaces in contact are clear of debris or dust.
  • Verify that the anvils and thimble move smoothly and don’t jam or stick.
  • If one is available, use a calibrated master gauge to do the first setting.
  • If you are measuring using just the anvil’s tip, set the point zero.
  • Keep in mind that changing the measuring head could have an impact on accuracy.
  • When necessary, swap out the SR44 battery.
  • To measure absolute values, enter a preset value.
  • When replacing, make sure the battery cap seal is seated properly.

During Use:

  • Employ the ratchet mechanism to apply a constant measurement force.
  • Anvil bearing surfaces should be shielded from impact.
  • Any mistakes or strange presentations should be fixed right away.
  • To avoid damage, do not withdraw the spindle farther than the measuring range.

After Use:

  • Check for damage and make plans for repairs if required. Make sure the instrument is clean.
  • Keep the container out of the heat, moisture, dust, and oil mist in a controlled atmosphere.
  • For long-term storage, apply micrometre oil on anvils and contact surfaces to prevent rust. Take out the battery.

In rigorous construction and engineering contexts, these checkpoints guarantee the correct operation, longevity, and accuracy of measurement devices such as the digital holtest.
