First let me introduce myself.
My name is Karel Wiersma and my adventure at 7Solutions started in 2017 when I started as an Account Manager.
Although bump testing or automatic calibration of a gas detector is very advisable whether it is for a sustainable or a disposable there is still many misconceptions of its true use.
7Solutions has its own service and maintenance department where we can service any gas detection instrument, no matter what brand or age.
