STARRETT 98-6 50441 Machinists Level, Graduated Vial, 6 Inch Length

Starrett 98-6 machinists level is suitable to use with various machines within a machine shop. This tool provides an absolute level setting of the machine's chassis, frame rails & cutting table, improving efficiency, reducing downtime and preventing costly errors.

Working Mechanism:

• Place the machinist level on the surface or object to be measured or aligned.
• Look at the ground and graduated vial bubble inside the vial housing. Adjust the object or surface until the bubble aligns with the centre graduation mark.
• For angular measurements, position the level at the desired angle. Align the bubble with the required angle marking on the graduated vial.
• Slowly adjust the object or machinery until the bubble aligns with the desired reference point on the graduated vial.
• Double-check the bubble's position for accuracy.
• Record readings or measurements for documentation.

Features:

• It features ground and graduated main vials for precise levelling & angular measurement for a wide range of precision applications.
• This machinist level has a glass vial filled with high-grade mineral oil to resist thermal expansion, contraction and excessive bubbles.
• It features a durable cast-iron base with an involute groove along its length, providing a reliable seat when levelling round items, such as pipes or shafts.
• This vial is housed in a satin chrome-finished brass tube with a friction-fit closing cover to prevent damage.

Frequently Asked Questions:

Q. What are the graduations on a Starrett 98 level?

A. Starrett 98 level has graduations (sensitivity) of 0.42 mm per meter or 80 - 90 seconds of arc to provide accurate results.

Q. Can the level be calibrated?

A. No, level measurement can't be calibrated as there is no standardised measurement process available for such devices.

Q. What is the use of a bubble level indicator inside of a machinists' level?

A. The bubble indicator is graduated to provide the exact level position in a much more precise manner than the carpenter's level.

Q. What are the graduations on Starrett 98-6 level?

A. Starrett 98-6 level has graduations (sensitivity) of 0.42 mm per meter or 80 - 90 seconds of arc to provide accurate results.

Q. Can I measure angles using this level?

A. Yes, the level can be positioned at the desired angle & the bubble's alignment with angle markings on the graduated vial allows for precise angular measurements.

Q. Is this level portable?

A. Yes, its compact size and lightweight design make it portable, enabling the user to carry it to different work locations easily.

Q. Is there a risk of damaging the vials if the level is dropped?

A. Careful handling is essential to prevent potential damage to the vials or compromise their accuracy, as dropping the level could lead to impact-related issues.

Q. How do I know if the bubble is aligned perfectly with the centre mark?

A. The bubble is aligned when it rests within the centre circle or marks on the vial. It is important to ensure that the bubble is centred.
