Calibrating and certifying your Danfoss refrigerant detector is an essential step to ensure accurate and reliable measurements of refrigerant gases. Regular calibration helps to maintain the detector’s sensitivity and performance, ensuring that it meets the necessary industry standards.
Before starting the calibration process, it is crucial to gather the necessary tools and equipment. This includes a calibration gas cylinder with the specific refrigerant gas you wish to calibrate for, an appropriate regulator, a flow meter, and a calibration adapter.
The first step in the calibration process is to connect the calibration gas cylinder to the regulator using the appropriate fittings. Then, connect the regulator to the flow meter and set the flow rate according to the manufacturer’s instructions. Place the calibration adapter onto the detector’s inlet and connect the other end to the flow meter. Ensure that all connections are secure and leak-free.
Once everything is set up, turn on the detector and allow it to warm up for the recommended time. Next, introduce the calibration gas into the detector using the flow meter. The gas concentration should match the desired calibration point. Allow the detector to stabilize and then adjust the detector’s zero and span if necessary. The zero adjustment compensates for any background signal, while the span adjustment aligns the detector’s response to the calibration gas concentration.
After making the necessary adjustments, repeat the process for multiple calibration points to ensure accurate and consistent results across different gas concentrations. Once the calibration is complete, the detector should be certified to confirm its accuracy and reliability. This certification should be done by a qualified professional and should include details such as the date of calibration, the calibration gas used, and the calibration points.
Regular calibration and certification of your Danfoss refrigerant detector are essential to ensure it continues to provide accurate and reliable measurements. By following the proper calibration process and working with qualified professionals, you can have confidence in the performance of your detector and trust its readings for your refrigerant gas detection needs.

How to Calibrate Danfoss Refrigerant Detectors
Calibration is an essential process for maintaining the accuracy and reliability of Danfoss refrigerant detectors. Regular calibration ensures that the detector is detecting and measuring refrigerant levels correctly, providing accurate and trustworthy results. Here are the steps to calibrate Danfoss refrigerant detectors:
Step 1: Preparation
Before starting the calibration process, ensure that you have the necessary equipment and materials. You will need a known concentration of the target refrigerant gas, a calibration adapter, a regulator, and a span gas cylinder. Make sure that all the equipment is clean and in good working condition.
Step 2: Setting Up
Locate the calibration port on the detector and connect the calibration adapter. Ensure a secure and tight connection to avoid any gas leaks during the calibration process.
Step 3: Calibration
Turn on the refrigerator detector and allow it to warm up for a few minutes. Follow the manufacturer’s instructions to enter the calibration mode on the detector. Once in calibration mode, introduce the known concentration of the target refrigerant gas through the calibration adapter. The detector should detect the gas and display the concentration value on the screen.
Step 4: Adjusting Calibration
Compare the displayed concentration value with the known concentration of the target refrigerant. If the values do not match, adjustment is required. Most Danfoss refrigerant detectors have specific adjustment screws or buttons for calibration. Follow the manufacturer’s instructions to adjust the calibration settings until the displayed value matches the known concentration value.
Step 5: Verification
After adjusting the calibration, repeat the calibration process to verify the accuracy. Introduce the known concentration gas again and ensure that the detector displays the matching concentration value. Repeat this verification process at regular intervals to ensure ongoing accuracy and reliability.
By following these steps, you can accurately calibrate Danfoss refrigerant detectors and maintain their performance over time. It is recommended to consult the detector’s user manual or contact Danfoss technical support for specific calibration instructions based on your model.
