Question 1

What is the SATA GL91531 Outside Micrometer 0-25mm and what can I measure with it?

Accepted Answer

The SATA GL91531 is a precision mechanical instrument used to measure external dimensions from 0 to 25 mm. It’s ideal for machining, engineering, and quality-control tasks where you need accurate outside measurements of parts or components.

Question 2

What are the main specs and features of this micrometer?

Accepted Answer

Key specs include a 0–25 mm measuring range, a high-resolution graduated scale for precise readings, a durable construction with hardened steel measuring surfaces, a precision spindle and anvil for smooth operation, a micrometer thimble with fine adjustment, a locking screw to secure measurements, and a protective ABS case for safe storage.

Question 3

How do I use the micrometer to take a measurement?

Accepted Answer

1) Clean the object to be measured. 2) Bring the spindle to lightly contact the object using the ratchet until you hear consistent, tactile click. 3) Check the reading on the scale and, if needed, use the thimble for fine adjustment. 4) Lock the measurement with the locking screw if you need to record or compare multiple parts.

Question 4

How should I read the measurement on this micrometer?

Accepted Answer

Reading typically involves the main scale for whole millimeters and the thimble for the finer fractional part. The display is designed to be clear and easy to interpret, so you can quickly determine the exact outside dimension of the part being measured.

Question 5

How do I zero the micrometer and lock in a measurement for consistency?

Accepted Answer

Close the spindle until the faces contact the measuring surfaces and observe the reading. If the zero point isn’t aligned, use the thimble or calibration procedure specified by SATA to set zero. Once you have the desired measurement, engage the locking screw to prevent drift during subsequent measurements.

Question 6

Why is the ratchet mechanism important on this micrometer?

Accepted Answer

The ratchet mechanism ensures you apply a constant, repeatable measuring force. This minimizes user-induced variation and improves measurement repeatability, which is especially important in precision work.

Question 7

How should I maintain and care for this micrometer?

Accepted Answer

Keep the measuring faces clean and free from dust and debris. Wipe with a soft, dry cloth after use. Store in the included protective ABS case to protect against impact and moisture. Periodically inspect for signs of wear and ensure the locking screw operates smoothly.

Question 8

What are common use cases for this outside micrometer?

Accepted Answer

It's well-suited for machining, engineering and quality-control tasks that involve checking external dimensions, verifying part tolerances, and ensuring consistent component sizing during manufacturing or prototype development.

Question 9

What safety considerations should I observe when using an outside micrometer?

Accepted Answer

Handle with care to avoid dropping or impacts that could misalign the spindle. Avoid forcing measurements beyond the 25 mm range. Keep the instrument clean and dry, and use the locking mechanism to prevent accidental changes during measurements.

Question 10

How does this micrometer compare to other similar options on Fepy, and where can I view those alternatives?

Accepted Answer

If you’re exploring other 0-25 mm outside micrometers on Fepy, you can compare similar models such as SATA GL91520 Outside Micrometer 0-25mm (https://fepy.com/product/sata-gl91520-outside-micrometer-0-25mm) and SATA GL91525 Outside Micrometer 0-25mm (https://fepy.com/product/sata-gl91525-outside-micrometer-0-25mm). These options offer comparable measurement ranges and features, so you can choose based on build feel, price, and availability.

Question 11

What comes in the package and is there anything special about the included case?

Accepted Answer

The micrometer typically ships with the instrument itself and a high-quality ABS plastic case. The case helps protect the instrument from dust and damage when not in use, contributing to longer-term accuracy and reliability.
