A vernier caliper in 0–150 / 200 / 300 mm range — IS 3651 / DIN 862 precision measuring instrument, digital and analogue variants available. Multi Trade Combines stocks genuine quality instruments in Guwahati for Northeast India; price on request.
The vernier caliper is the first and most fundamental precision measuring instrument found in any machine shop, quality-control lab or engineering workshop. It measures external dimensions (outer diameter, width, thickness), internal dimensions (bore diameter, groove width), depths (hole depth, recess depth) and step heights — all with a single tool. Multi Trade Combines in Guwahati stocks vernier calipers in ranges of 0–150 mm, 0–200 mm and 0–300 mm, available in both digital and analogue (vernier-scale) variants, catering to inspection rooms, ITI labs and fabrication workshops across Northeast India.
The hardened stainless steel jaw construction ensures long-term accuracy if the instrument is handled correctly and stored in its protective case when not in use. On digital models, the large LCD display reads in both metric (mm) and imperial (inch) with a single button press — convenient for engineers working to both IS-metric drawings and older imperial specifications. Analogue calipers with a 50-division vernier scale resolve to 0.02 mm — more than adequate for most workshop fittings and turned-part inspection.
Across Northeast India's growing manufacturing and fabrication sector, vernier calipers are in daily use. Auto-component workshops in Guwahati's industrial areas use them to check machined bores and shaft diameters. Welding fabricators use calipers to verify wall thickness of structural tubes. Civil and materials-testing labs at MSME tool rooms, polytechnics and ITIs across Assam, Meghalaya and Manipur use them for student training and component measurement. Quality-control departments at tea-estate machinery workshops verify bearing fits and replacement-part dimensions with calipers before assembly.

Precision machining workshops in Guwahati's light-industrial estates use vernier calipers for every turned and milled component. Automobile workshops and spare-parts reconditioning units check cylinder bore wear, piston-ring groove width and gudgeon-pin diameters with digital calipers. MSME fabricators bidding on government contracts for fabricated components must submit dimension-inspection reports — vernier calipers are the baseline instrument. ITI and polytechnic surveying and machining students across all NE states are assessed on caliper reading as part of their practical examinations. Research institutes and engineering colleges in Guwahati use Mitutoyo-standard calipers for lab experiments. Multi Trade Combines has supplied calibrated measuring instruments to the NE engineering community since 1993 and can advise on the right specification for your application.
A vernier caliper is part of a wider measurement toolkit that includes an outside micrometer (for higher-precision diameter measurement), a dial gauge with magnetic stand (for run-out and deflection measurement), a steel rule (for quick linear measurements), and a combination square (for squareness and 45° checks). A calibration certificate and carrying case protect investment in quality instruments. Multi Trade Combines stocks the full precision-measurement range — buy a caliper and micrometer set together for a complete workshop inspection station.
The least count is the smallest measurement increment a vernier caliper can resolve. Standard analogue vernier calipers have a least count of 0.02 mm (50-division vernier scale), while digital vernier calipers display to 0.01 mm. In precision machining and inspection, the least count determines whether the caliper is suitable for a given tolerance — a 0.02 mm least count is usually adequate for general-purpose turning and fitting work in workshop settings across Northeast India.
Digital vernier calipers are faster to read, eliminate parallax error and are preferred for high-throughput inspection. However, they require battery replacement and are more sensitive to coolant ingress. Analogue vernier calipers have no batteries, are more robust in rough workshop conditions and remain accurate indefinitely if not dropped or overloaded. For ITI/polytechnic students and field technicians, analogue models are often recommended. Multi Trade Combines stocks both types in Guwahati — call +91 91812 13332 for a recommendation.
