Why calibrate an analyzer?

Why calibrate an analyzer?

• A. To ensure viable readings
• B. To save energy
• C. To adjust sensitivity
• D. To extend battery life

Answer: (A)

Calibration brings an analyzer’s readings into agreement with a known reference. Over time sensors drift due to aging, wear, temperature changes, and contamination, so the raw output can diverge from the true value. By comparing the instrument’s output to trusted standards and making adjustments, you restore accuracy across the instrument’s range. This ensures the data you rely on for process control, safety decisions, regulatory compliance, and troubleshooting are reliable and meaningful. Energy use or battery life aren’t the primary goals of calibration, and while some setups involve changing gain or sensitivity, the core purpose remains keeping measurements accurate and usable.
