When should I get my breathalyser calibrated?
After 12 months of use your breathalyser will require re-calibration to ensure it continues to read accurately. Over time the sensor in the breathalyser can 'drift', reducing the accuracy of the readings you receive. This affects all breathalysers, whether they are a £15,000 Police unit or a consumer breathalyser.
If your breathalyser is saying its calibration is expired, providing inconsistent test results, is not providing any test results, or provides unusually high or low test results, the product should be calibrated immediately by an AlcoSense technician.
If you have not had your breathalyser calibrated for more than 12 months don't worry, we can still calibrate it for you. However, the longer the breathalyser is outside it's calibration window, there is a higher likelihood that the sensor may not be able to be recalibrated.
How do you calibrate my breathalyser?
AlcoSense's trained technicians will recalibrate your breathalyser using wet bath simulators, the gold standard in breathalyser calibration and accuracy checking equipment - as used in the servicing of Police breathalysers worldwide. A wet bath simulator generates a known and consistent concentration of alcohol and water vapour in air which is used to calibrate the breathalyser, simulating human breath with alcohol in it. Using this known value we can then adjust your breathalyser to read the known sample accurately, resetting the calibration.
Calibration takes place in AlcoSense's purpose built laboratory in Maidenhead, Berkshire. Our technicians will run a full diagnostic test on your breathalyser during calibration to ensure it is working correctly. Once calibrated it is then tested for accuracy before being returned to you.
Do I need a calibration certificate?
A calibration certificate is a document which contains details of your unit, it’s calibration date and calibration results. This is only required when a unit may be used for testing people in an environment where there may be social responsibility, for example in a corporate or work environment. In this instance you should keep the certificate in your files for future reference if required. Calibration certificates are only available for the AlcoSense Excel, Pro and Ultra.
Regardless of whether you purchase a certificate the calibration service your breathalyser receives is identical. The certificate is a chargeable option to cover the cost of the additional paperwork and record keeping required. For personal use a certificate is not normally required.
