Heat Detector Testers
Like smoke detectors, international codes and standards require that heat detectors be tested regularly using an appropriate heat source.
We offer several products to meet these requirements – with each offering reliability, value for money, and a solution that complies with codes and standards and comes with the approval of detector manufacturers. We pride ourselves on offering genuine product choice whilst providing a solution that will meet your needs and budget.
“Testifire certainly speeds up servicing – only one tool to carry, no changing of heads, the clearing facility is fantastic and the capsules seem to last for ages”
