How We Work:
Before calibrating, we disassemble your backflow test kit in order to ensure that all the internal components work within specifications and clean out any dirt or debris that may lead to inaccurate results.
We then calibrate your device to the required standard. If you are required by your municipality or client to provide an accredited calibration certificate, Marsh Metrology is fully ISO 17025:2017 accredited and authorized to provide you with a fully traceable ISO 17025:2017 Accredited Calibration Certificate.
