SGD 240

LEAK DETECTOR FOR UNDERGROUND NETWORKS

FORMING GAS, N2/H2 TRACER GAS & NIDRON

The SGD 240 is a portable gas leak detector for the detection of hydrogenated nitrogen gas (forming gas), nidron or N2/H2 tracer gas. Designed for leak testing of underground or buried networks by sniffing at atmospheric pressure.

In the same range:

For general portable H2/N2 or Nidron detection (not specific to underground networks), the DXH 240 offers 4 sensitivity positions and 2 detection modes.

Accessories:

For quick SGD 240 sensitivity verification, use the FT 92-T test leak (equivalent to 5 g/year, for H2/N2 mixture on request).
