EX-TEC® HS 6XX range of gas detectors

A unique family of high performance gas measuring and alarming devices for personal safety and gas distribution network leak monitoring

The new standard in combination measuring instruments for gas utilities

EX-TEC® HS 680 multi purpose gas measuring and detecting device

The high performing new HSXX range of instruments continues to build on Sewerin's many year's of experience designing and building advanced gas detection instruments The new HSXX range of gas measuring and warning devices can be used for all gas detection applications including:

Personal gas warning for toxic, asphyxiant and explosive gases

Gas Network leakage surveys

Purging gas pipelines

Measuring gas in bar holes

detecting flammable gas leaks in houses

Simple to use

Gas concentration display on HS680 gas detector and measuring device

Designed to be both simple and easy to use, whilst not compromising on performance, all functions are clearly shown by logical pictorial representations of the measuring application.
One "jog dial"and 3 buttons control all the many possible measuring modes of this versatile gas measuring, monitoring and warning instrument

More precise gas leak pin pointing

Finding methane gas leaks using oxygen and methane sensrs

If a gas leak has dispersed over a wide area, it is often difficult to precisley pinpoint the leak source .
Often the gas gathers under the surface and spreads over long distances.
The oxygen content decreases nearer the source of a leak and the methane gas level increases
By utilising the optional oxygen sensor the user can measure and display the oxygen minimum at the same time as the methane maximum. This minimum oxygen level, with its smaller diffusion area, makes it easier to locate complex leaks more precisely.

Is it natural gas or marsh gas?

No more wasted excavations. The HS680 can differentiate between marsh, natura, and propane gas
The HS680 is unique in having the option of an on board Ethane gas chromatograph which allows the instrument to differentiate between marsh, propane and methane gas.
Marsh gas does not contain ethane but natural gas does.
