Depth Gauge INSIZE 1240-150 MAGA 150 mm / 100 mm range, 0.05 mm resolution

INSIZE 1240-150 MAGA depth gauge is a manual precision instrument designed for measuring depths, steps and recesses in metalworking, machining and inspection environments. With a measuring length of 150 mm and an effective measuring range of 100 mm, this tool offers a resolution of 0.05 mm for decisive manual readings where quick, repeatable depth measurements are required.

Advantages

The depth gauge combines a compact 150 mm body with a 100 mm usable range to balance portability and measurement capability. Its 0.05 mm resolution allows detection of fine depth differences, and the clear graduated scale supports straightforward interpretation of results without electronics. The instrument is robust enough for workshop conditions and simple to operate for technicians and inspectors who need consistent, mechanical depth readings.

Suitable for

• Measuring depths of drilled holes, counterbores and recesses
• Checking step heights and shoulder depths on machined parts
• Quick in-process inspections on the shop floor
• Quality control verification in production and assembly

Key specifications

• Measuring length: 150 mm
• Effective measuring range: 100 mm
• Resolution: 0.05 mm
• Manual, non-electronic graduated scale
• Designed for depth and step measurement in workshop environments

How to use

Place the base of the depth gauge flat on the reference surface so it sits steadily. Lower the measuring spindle into the hole or recess until it contacts the bottom, then read the depth value from the graduated scale aligned with the reference edge. For step measurements, rest the base on the higher surface and extend the spindle to the lower surface, then read the scale. Ensure the gauge is held perpendicular to the measured surface to avoid parallax and angular errors.

Usage recommendations

Handle the instrument with care to maintain calibration: avoid heavy impacts, keep the scale clean from chips and coolant, and store the gauge in a protective case when not in use. For more repeatable results, check the zero reading on a known reference and use consistent seating pressure when taking measurements.
