Calibration

Calibration is an essential process to ensure that industrial instruments and devices operate with maximum accuracy, reliability, and safety. At Husaini® Engineers, our specialized calibration services provide comprehensive solutions for a wide array of equipment, including gas detectors, pH controllers, and turbidity sensors. With a commitment to high standards, we guarantee peak performance for your devices while ensuring compliance with regulatory norms.

Our instruments are factory-tested and calibrated to provide unmatched precision and reliability. We also offer calibration tools and expert guidance for on-site calibration. Contact us to learn more about our calibration solutions and keep your operations running smoothly and efficiently.

Calibration may be necessary under the following circumstances:

• New Instruments: To establish a baseline of accuracy before use which is done at the factory before Dispatch.
• Post-Repair or Modification: Ensures the integrity of measurements after adjustments or repairs.
• Time-Elapsed Calibration: Following a specific time period as recommended by the manufacturer or industry standards.
• Operational Usage: After prolonged operating hours or heavy use.
• Critical Measurements: Before and after significant measurements to ensure accuracy.
• Post-Event: After incidents like physical damage, shocks, vibrations, or sudden weather changes.
• Questionable Observations: When output differs significantly from expectations or surrogate instruments.
• Compliance: As mandated by customer specifications or manufacturer recommendations.

Key Benefits of Calibration:

• Minimized Operational Downtime: Calibration can be performed on-site without requiring hot work permits, reducing disruptions.
• Ease of Use: Instruments are designed with local displays and buttons, enabling calibration without opening the junction box.
• Accuracy Assurance: Aligns the instrument’s output to a known standard, ensuring precision and compliance with specified accuracy.

Calibration at the field can be conducted using a high-pressure canister of known PPM (parts per million) in a calibration chamber. Below is a step-by-step overview:

• Preparation: Ensure the instrument is turned on and connected to the sensor. The display should show a zero reading.
• Set the Calibration Chamber: Insert the tubing, align the chamber and secure it with the Canister C10 Valve.
• Seal the Sensor: Remove the sensor guard and place the sensor inside the calibration chamber. Seal tightly to ensure it is leak-proof.
• Introduce the Calibration Gas: Open the C10 Valve slowly, view the flow at flowmeter having constant flow of 1 LPM and allowing the calibration gas to diffuse into the chamber.
• Read and Adjust: Check the display. If the reading does not match the PPM of the canister value, adjust Pot-4 until the reading aligns accurately.
• Completion: The instrument is now calibrated and ready for use.

Importance of Calibration:

• Enhanced Accuracy: Ensures reliable measurements, especially in critical applications.
• Extended Instrument Life: Regular calibration helps maintain the integrity of the sensor and overall equipment.
• Safety Compliance: Meets industry standards and regulatory requirements for operational safety.
• Efficiency: Reduces measurement errors that could lead to costly downtime or equipment damage.
