Our Gas Mixers are mostly supplied pre-set with a test certificate. They are extremely easy to install and mostly do not include a need for power or additional buffer tanks.
We encourage our customers to look after the equipment themselves. Which is exactly what happens in most cases. Although we pride ourselves on rapid response when customers do have problems.
Occasionally we are asked if we will attend site to update the original test certificate. If you require this service for your QA procedures we will be pleased to assist you!
