Top 5 Mistakes to Avoid When Buying Calibration Weights in Gujarat

Introduction

Calibration weights are a one-time investment — but making the wrong choice can cost your business recurring losses, legal issues, or failed audits.

At Shree Shree Weighing Solutions, we often help clients who made costly mistakes when buying their first set of iron weights or SS 304 bullion weights.

Avoid these 5 common pitfalls and buy smart.

❌ Mistake 1: Buying Non-Certified Weights

It may be tempting to save money by purchasing low-cost, uncertified weights from unverified sources. But this can lead to:

• Failed Legal Metrology inspections

• Rejection during NABL audits

• Inaccurate weighing

• Legal penalties

✅ Always insist on BIS-certified or OIML-class weights from an authorized dealer.

❌ Mistake 2: Choosing the Wrong Material

Using iron weights in labs or jewellery stores is a mistake. They corrode easily and don’t provide micro-level accuracy.

✅ Use SS 304 stainless steel weights for precision environments. Reserve iron weights for industrial calibration and weighbridge applications.

❌ Mistake 3: Ignoring Legal Metrology Stamping

Even if your weights are certified, they’re not legally usable unless they’ve been stamped by the Weights & Measures Department.

✅ We offer legal metrology stamping with full documentation, so you're compliant from Day 1.

❌ Mistake 4: Not Matching Class and Use

Every weight is classified by tolerance — Class E1, E2 (high precision), F1, M1 (general use).

✅ Match your weights to your application:

• E1/E2 for gold testing

• M1 for platform scales

• F1 for weighbridges

❌ Mistake 5: Not Planning for Recalibration or AMC

Weights need to be re-certified annually. Buying from vendors who don’t offer this service puts you at risk later.

✅ Shree Shree provides AMC contracts, recalibration services, and certification renewal support.
