The Mitutoyo 145-194 caliper jaw inside micrometer measures internal diameters, grooves and slot widths from 1"–2" (25.4–50.8 mm) using caliper-style jaws with carbide faces. It is a battery-free, workshop-ready choice for measuring internal features. Request a quote in under a minute by calling or WhatsApping +965 9807 4888.

Internal grooves, short bores and slots can be difficult to reach with a tubular inside micrometer. The Mitutoyo 145-194 caliper jaw inside micrometer uses caliper-type jaws that enter the feature, allowing measurement directly between the internal walls.

Carbide measuring faces resist wear from repeated contact, while the mechanical thimble provides a clear 0.001" graduation. Because it is fully mechanical, there are no batteries to replace or electronic components to depend on during remote-site work or maintenance shutdowns.

The 1"–2" measuring range is suitable for bearing housings, internal grooves, slots and short bores. It is useful for machine shops, power and desalination plant maintenance teams, gearbox, pump and valve rebuild shops, and oil and gas service contractors in Kuwait.

For best accuracy, set the micrometer against an appropriate setting standard before measurement. Allow the Mitutoyo 145-194 and the workpiece to reach the same temperature before taking a final reading. Steel expands with temperature, so thermal differences can affect close-tolerance measurements.

Need a larger range? See the Mitutoyo 145-196 for 3"–4". Want a digital readout? The Mitutoyo 345-351-30 Digimatic inside micrometer covers the 1"–2" range.

How to Use

1. Check the micrometer reference or zero using a suitable setting standard of known size.

2. Insert the caliper jaws into the bore, groove or internal feature.

3. Rock the micrometer gently to locate the true maximum internal measurement.

4. Turn the thimble until the carbide measuring faces make proper contact with the walls.

5. Apply consistent measuring pressure and read the sleeve and thimble graduations.

6. Clean the measuring faces after use and return the instrument to its case.

FAQ

What range does the Mitutoyo 145-194 caliper jaw inside micrometer measure?
It measures internal features from 1"–2" (25.4–50.8 mm) with a 0.001" graduation.

What is a caliper jaw inside micrometer used for?
It is used to measure internal diameters, groove widths and slot widths where a tubular inside micrometer or bore gauge may not easily reach.

What are the measuring faces made of?
The measuring faces are carbide, providing resistance to wear from repeated contact.

Do I need a setting standard?
A setting standard is recommended for establishing an accurate reference before measurement. The appropriate standard should cover the measurement range being checked.

Does the Mitutoyo 145-194 require batteries?
No. It is a fully mechanical inside micrometer, so it does not require batteries or electronic power.

Which model should I choose if my part is outside 1"–2"?
Choose a model whose measuring range brackets the required internal dimension. The Mitutoyo 145-193 covers 0.2"–1.2", while the Mitutoyo 145-196 covers 3"–4".

Can the Mitutoyo 145-194 be recalibrated?
Yes. The micrometer can be periodically calibrated through a suitable calibration service to maintain measurement accuracy and traceability.

How should I store and care for the Mitutoyo 145-194?
Wipe the carbide measuring faces clean after use, keep the instrument protected from coolant and contamination, avoid dropping it, and store it in its case when not in use.

How do I order the Mitutoyo 145-194 in Kuwait?
Pricing is quote-based. Provide the model number and required quantity when contacting the supplier.
