Esspron Breathalyzer Calibration — Complete Guide

Regular calibration is not optional for professional breathalyzers — it is a legal requirement in India for law enforcement use and a safety necessity for industrial applications. Here's everything you need to know about breathalyzer calibration and how Esspron's service works.

How Often Should You Calibrate?

• Law enforcement / legal use: Every 6 months or after every 500 tests, whichever comes first
• Industrial / workplace: Annually, or per manufacturer recommendation
• High-frequency use (>10 tests/day): Every 3–4 months
• After any drop or impact: Immediately, before using again
• If readings seem inconsistent: Immediately

What Happens During Calibration?

1. Zero-point verification — device reads 0.000 in clean air
2. Span calibration — certified reference gas at known concentration is passed through the device; reading is adjusted to match
3. Linearity check — multiple concentration points tested
4. Certificate issuance — NABL accredited certificate with calibration data, uncertainty values, and next due date
