Can I use Insize depth gauges near CNC coolant?

Yes, the Insize 1149 series is IP67 waterproof and designed for use in coolant-heavy environments including CNC machining centres and grinding machines. Standard models (1141 series) should be kept away from direct coolant contact. Both are available at Shri Narayan Machinery LLP, Noida.

Which Insize depth gauge is most popular in Indian machine shops?

The Insize 1141-150A (0-150mm digital depth gauge) is the most widely used model across Indian manufacturing. For budget-conscious shops, the 1240-2001 vernier depth gauge (0-150mm, 0.02mm graduation) offers excellent value without needing batteries. Both are stocked at our Noida location.

Insize Digital Depth Gauges & Depth Micrometers

Name: Insize Digital Depth Gauges & Depth Micrometers
Brand: Shri Narayan Machinery LLP

Insize depth gauges and depth micrometers enable accurate measurement of step heights, slot depths, hole depths, and recesses across Indian manufacturing operations. Available from Shri Narayan Machinery LLP in Noida, the range includes standard digital depth gauges (1141 series) with 0.01mm resolution and interchangeable measuring rods for extended range, IP67 waterproof digital depth gauges (1149 series) for use near grinding coolant and wash stations, dial depth gauges (1340, 2342 series) for mechanical reliability, vernier depth gauges (1240 series) for battery-free measurement, and precision depth micrometers (3240, 3540 series) delivering 0.01mm to 0.001mm resolution for critical depth tolerances. Hook depth gauge variants (1142, 1245 series) measure from internal shoulders and blind features. Extension bases (6141 series) widen the bearing surface for stable measurements on large workpieces. From checking keyway depths on shafts to verifying counterbore depths in engine blocks, Insize depth gauges cover every depth measurement application. Contact our Noida showroom for a quote.

Frequently Asked Questions — Depth Gauges

A depth gauge (1141 series) uses a sliding scale similar to a caliper — it has wider range (up to 1000mm with rods) and is faster for routine measurements. A depth micrometer (3240, 3540 series) uses a thimble mechanism like a micrometer — it offers higher accuracy (±0.004mm vs ±0.02mm) and is preferred for precision depth measurements in quality labs. Choose based on your accuracy requirement and measurement range.
