Insize - Vernier Depth Gauge 1240-150- Range 0-150mm - 1240-200 - 0-200mm
The Insize Vernier Depth Gauge is a precision measuring instrument used to measure the depth of holes, slots, steps and recesses on machined parts. It is a standard toolroom and QC instrument for machinists and inspectors, and is stocked and supplied by SAN Tools across our Dubai, Sharjah and Ajman branches in the UAE.
Key features
- Vernier scale reading — a mechanical vernier caliper-type scale gives a direct depth reading without a battery.
- Wide-base design — a flat measuring base sits across the top of the feature being measured while the rod is lowered to the bottom of the hole, slot or step.
- Multiple range options — supplied in three ranges (0-150mm, 0-200mm and 0-300mm) to suit different part sizes.
- Genuine Insize instrument — from Insize's precision measuring instrument range, alongside their calipers, micrometers and gauges.
Applications
- Measuring the depth of blind holes, pockets, slots and steps on machined components
- Toolroom and QC inspection of finished parts
- General workshop measurement wherever a depth reading is required, alongside standard calipers and micrometers

How to choose
- Select the range (150mm, 200mm or 300mm) based on the deepest feature you need to measure — choosing a range close to your typical depth keeps the instrument easier to handle.
- Make sure the base is fully seated and square across the reference surface before taking a reading, as tilting the gauge will give a false depth.
- For readings requiring finer resolution or digital/electronic output, ask our team about Insize's digital depth gauge options.
Frequently asked questions
What is the difference between the 1240-150 and 1240-200 models?
They are the same vernier depth gauge design in different measuring ranges — 1240-150 measures 0-150mm and 1240-200 measures 0-200mm, letting you pick the range that suits your typical part depth.
Do I need to zero the gauge before use?
Yes — as with any vernier instrument, check the zero reading on a flat reference surface before taking measurements, and confirm the vernier scale reads zero when the rod end is flush with the base.
