Introduction
The leak detector 8PE 351 224-071 has long-life heated sensors which can not only prove the presence of all refrigerants containing HCFCs (e.g.
R22, R123, R124, R142b) and CFCs (e.g. R12) but also the more common and difficult refrigerants containing HFCs e.g. R134a, R125, R32, R143a,
R152a, R404A and R407A, including all SMAPs (Short and Medium-term Priority Environmental Action Programmes) of approved hydrocarbon
compounds.
With the unique D-440 digital leak detector, you no longer have to wonder how serious the leak is. The digital display works independently of the
acoustic alarm and sensitivity level and allows the source of the leak to be located exactly.
The D-400 can either be operated with rechargeable batteries or with 4 standard AA alkali batteries. When rechargeable batteries are used, care
must be taken that they are charged properly.
