” I bought the item for my niece as a christmas present, she has used it a few times and has been really happy with it. The company also nails the customer service aspect, going above and beyond, and really quick to respond to any messages. Will only buy through Dave and the company in the future,
thank you so much! “

“Used it for the 1st time on the weekend. I think its pretty accurate as I have a Interlock in my car previously. And know where I’m at usually. Great device. Just would like to know when I should calibrate it?”
Peter M.
” The Breatho was shipped on the day of order and received well before I expected. Very simple to use and a convenient way to have a quick check on how you’re travelling after a couple of quiet ones. Very happy camper so far. “

Calibration ensures your breathalyser provides accurate BAC readings. Over time, sensors can drift, which affects reliability. Regular calibration helps maintain consistent results. It is especially important for workplace and professional use.
Most breathalysers require calibration every 6 to 12 months. Frequency depends on usage volume and device type. High-use or workplace devices may need more frequent calibration. Always follow the manufacturer’s recommendations.
A standard service includes testing accuracy, calibrating the sensor, and checking overall device condition. Worn components may be repaired or replaced if required. The device is then verified for reliable performance. Servicing helps extend the lifespan of the breathalyser.
Calibration turnaround times vary depending on the device and service provider. Many calibrations are completed within a few business days. Some services offer express options. Timeframes should be confirmed when booking.
Inconsistent readings, error messages, or delayed responses can indicate the need for servicing. Devices used frequently may also require routine servicing. Reduced accuracy is a common sign. Regular servicing helps prevent unexpected issues.
