What is the advantage of carbide tipped vernier calipers (Insize 1238 series)?

Carbide tipped jaws last 5-10 times longer than standard hardened steel when measuring abrasive materials like cast iron, sintered metal, graphite, and hardened steel above 50 HRC. If your shop routinely measures castings or hardened workpieces, the 1238 series holds its accuracy far longer than standard jaws.

How do I read 0.02mm graduation on an Insize vernier caliper?

The main scale reads in 1mm increments. The vernier scale has 50 divisions spanning 49mm, giving a least count of 0.02mm. Align the zero of the vernier scale against the main scale to read the mm value, then find the vernier division that best aligns with a main scale line to get the 0.02mm fraction. Detailed reading guides are available from our Noida team.

Insize Vernier Calipers: Standard, Ceramic Tipped, Heavy Duty & Mini

Name: Insize Vernier Calipers: Standard, Ceramic Tipped, Heavy Duty & Mini
Brand: Insize

No battery, no electronics: Insize vernier calipers give you 0.02mm graduation on the standard 1205 series and keep reading through dust, coolant, and rough handling. The range runs from compact mini models (1201, 1203 series) for confined spaces up to 0-2000mm heavy-duty solid types (1208, 1236 series) for large fabrications. The 1238 series adds carbide tipped jaws for abrasive cast iron and hardened steel, and the 1233 series has a fine adjustment screw for critical measurements. Construction is hardened stainless steel with a satin chrome, laser-etched scale to DIN 862, plus a knurled locking screw on every model. Fabricators, foundries, ITI training centres, and field service technicians across Noida-NCR keep these as their everyday and backup measuring tools. Stocked at Sector 9, Noida; WhatsApp for price.

Frequently Asked Questions: Vernier Calipers

Vernier calipers need no battery, are unaffected by coolant or dust on electronics, and are extremely durable in harsh workshop environments. They're also preferred in ITI and polytechnic training because students learn to read the vernier scale manually. Many experienced machinists in India still trust vernier calipers for their simplicity and reliability. Shri Narayan Machinery LLP stocks the full Insize vernier caliper range in Noida.
