Drop your testers off before Tuesday 27th July 2021 for calibration on that day. Unfortunately, arrivals after this time cannot be guaranteed to be calibrated on the day**. We also offer a free of charge collect and delivery service please ask for details.

Not due for calibration yet?
Don’t worry, you can still benefit from our excellent prices. We will reduce the amount you pay by how much calibration is left on your meter*. You will then benefit from calibration day prices every year.

* Current certificate must be shown to qualify for reduction.
** Most makes calibrated on the day some may require returning for calibration
