Metal Detector Calibration

Q: Do you offer on-site calibration, or do I need to send the equipment to you?

We offer both options to minimize your downtime: On-Site Calibration: Our certified engineers can come to your facility to perform the service. This is ideal for fixed or hard-to-move systems and allows us to test the detector within your production line. In-Lab Calibration: For smaller, portable units or when on-site work is not feasible, you can ship the detector to our laboratory. Please contact us to discuss which option is best for your specific metal detector model and situation.

Metal Detector Calibration Service

Ensure Accurate Detection

In industries such as food, pharmaceuticals, security, and mining, metal detectors are the first line of defense for product quality and safety. Nevertheless, an uncalibrated metal detector can pose significant risks to you, from product contamination recalls to brand reputation damage. Hence, how can you ensure that your device is always in optimal condition? The answer lies in professional metal detector calibration services.

What is metal detector calibration service?

Metal detector calibration services are a series of professional testing and adjustment processes aimed at ensuring that your metal detector can continuously and reliably detect specific sizes of metal impurities in accordance with the manufacturer’s standards and industry regulations.

This is not just about ‘passing a test sample’. It involves using certified test pieces (such as iron, non-ferrous, and stainless steel) to conduct systematic testing throughout the entire testing channel of equipment operation. Technicians will validate the core parameters of the equipment, such as sensitivity, phase, and balance, based on the test results to ensure that its “vision” is clear and accurate.

Why is calibration crucial? Not just compliance

You may think that if the device is running, there is no need to pay too much attention. But the fact is not so. Regular metal detector calibration services are a key strategy for proactive risk management, mainly due to the following reasons:

Ensuring product safety and compliance: Regular calibration is a mandatory requirement for food safety standards such as HACCP, ISO 22000, BRCGS, etc. It is your passport to market access through third-party auditing.
Maintain the highest detection accuracy: Environmental temperature changes, mechanical vibrations, and equipment aging can all cause detector performance to drift. Calibration can promptly correct this drift, ensuring that even the smallest metal fragments have nowhere to hide.
Reduce business risks: A missed metal pollutant may lead to costly product recalls, customer claims, and brand reputation collapse. The cost of calibration is much lower than the loss of a recall event.
Optimize production efficiency: A precise detector can minimize false alarms, thereby reducing unnecessary production downtime and improving overall operational efficiency

Step 1: Preliminary evaluation and setup

Engineers will inspect the appearance, cleanliness, and installation environment of the equipment. Subsequently, set the standards for this calibration in the software, including target sensitivity (e.g. Fe 1.5mm, SUS 2.0mm) and corresponding detection frequency.

Step 2: Sensitivity testing and benchmark establishment

Use standard test strips to pass the test at multiple positions (center, left, right, front, rear) on the conveyor belt or inspection aperture. Record the signal strength successfully detected by the device each time, which establishes the benchmark for the current performance of the device.

Step 3: Fine tuning of parameters

This is the technical core. If the test finds a decrease or inconsistency in sensitivity, the engineer will enter the advanced settings menu of the device. Optimize the recognition ability for specific metals such as iron or stainless steel by adjusting the Phase Angle, and fine tune the Gain and Signal Threshold to achieve a perfect balance between sensitivity and anti-interference ability.

Step 4: Verification and documentation

After the adjustment is completed, use the same set of test pieces for final verification to ensure that the equipment can stably and reliably alarm in all positions. Finally, Premier Calibration Sdn Bhd will provide a detailed calibration certificate that includes calibration dates, standard information, test results, and qualified conclusions, providing strong evidence of your compliance.

Material used for testing include : Ferrous Chrome, Aluminum 2017, Brass, stainless steel (SS316)

FAQ: Metal Detector Calibration Service

How often should my metal detector be calibrated?

We recommend calibration at least once per year. However, the optimal frequency can depend on several factors, including:

Industry Regulations: Your specific certification standards may require more frequent checks.
Usage Intensity: High-volume production lines may need semi-annual or quarterly service.
Environmental Conditions: Harsh environments (e.g., high humidity, temperature swings, vibration) can affect performance more quickly.
Our service technicians can help you determine the best schedule based on a risk assessment of your operation.

What is included in your standard calibration service?

Our comprehensive calibration service for metal detectors is a complete check-up for your equipment and includes:

Performance Verification: Testing sensitivity with certified test samples (ferrous, non-ferrous, and stainless steel).
Mechanical Inspection: Checking the housing, conveyor belt (if applicable), and rejecting the system for proper function.
Functionality Check: On/ Off, display, or the platform is at the correct level, but full software validation shall be referred to the software supplier.
Full Documentation: You will receive a detailed calibration certificate traceable to national standards, which serves as proof of compliance for your audits.

Do you offer on-site calibration, or do I need to send the equipment to you?

We offer both options to minimize your downtime:

On-Site Calibration: Our certified engineers can come to your facility to perform the service. This is ideal for fixed or hard-to-move systems and allows us to test the detector within your production line.
In-Lab Calibration: For smaller, portable units or when on-site work is not feasible, you can ship the detector to our laboratory.
