Insize Outside Micrometers: Digital, Analog, Disc & Blade Types
When a caliper's accuracy isn't enough, Insize outside micrometers take you to 0.001mm resolution on the digital 3109 and IP65-rated 3101 series, with ±0.002mm accuracy on the 0-25mm size. The analog 3203 series with 0.01mm graduation stays the shopfloor staple, while 3105 quick-feeding models speed up production sampling. Disc micrometers (3282 series) handle gear tooth thickness and thin walls, and blade micrometers (3232 series) get into keyways and narrow grooves. Units measure in 25mm bands, with sets to 0-150mm and interchangeable anvil models extending coverage to 500mm; the ratchet stop keeps measuring force at a consistent 5-10N across operators. Bearing, gear, and automotive component plants around Noida rely on them for micron-level checks. Stocked at Sector 9, Noida; WhatsApp for price.
