Insize Outside Micrometers — Digital, Analog, Disc & Blade Types
Insize outside micrometers provide sub-micron precision for Indian quality labs, tool rooms, and production floors requiring measurements beyond caliper accuracy. Available from Shri Narayan Machinery LLP in Noida, the lineup spans digital outside micrometers (3109 series standard, 3101 series waterproof IP65, 3105 series quick-feeding) with 0.001mm resolution, analog micrometers (3203 series) with 0.01mm graduation that are the backbone of every Indian machine shop, disc micrometers (3282 series) for measuring gear tooth thickness and thin-wall tubing, and blade micrometers (3232 series) for narrow groove and keyway measurement. Ratchet stop mechanisms ensure consistent measuring force across operators. With ranges from 0-25mm through 275-300mm in standard increments, and interchangeable anvil sets (3206 series) for extended coverage, Insize outside micrometers handle every external dimensional measurement your shop demands.
