**-Protect health of people by Figaro sensors
**-Gases like hydrogen sulfide and ammonia are dangerous gases, which however can be easily detected.
Hydrogen sulfide and ammonia are relatively common gases arising at an organic
material decay, in sewage conduits, poultry farms, and in a technological
process of many industrial segments. Despite of the fact, that both gases are
irritative and feature a pungent smell, intoxications by these gases aren´t
rare. Risk is also increased by a fact, that already after a short exposition to
these gases, they subjectively appear to be much less concentrated.
- high sensitivity to target gases
- long lifetime
- resistant to severe environment
For a production of devices detecting these gases are suitable Figaro sensors
TGS8xx series. TGS825 is sensitive to hydrogen sulfide already from 5
TGS826 is sensitive to ammonia, as well as ethanol,
iso-butane and hydrogen. TGS826 is able to detect ammonia already from 30 ppm
concentration, that´s why it is suitable for all critical safety-related
applications in refrigeration systems and in agriculture. Both sensors use SnO2
based semiconductor sensors featuring high sensitivity and a long lifetime.
Sensors are made on a ceramic base resistant to severe environment.
Usage of both sensors is further facilitated by the
SR-2 socket. SR-2 is usable for all Figaro sensors
TGS8xx series and it enables a troublefree exchange without a necessity of
relatively demanding desoldering from a PCB.

Figaro sensors feature a long lifetime, high sensitivity
and selectivity to target gases. Despite a long lifetime, in an environment with
a high dust nuisance or an aggressive environment, it can be necessary to
exchange a sensor after some time. This is also the case of applications where
highest reliability and accuracy is required. An easy sensor exchange is also
welcome at development or at the change of a sensor type. SR-2 socket, with an
over 1000 MOhm insulation resistance and 700V AC insulation strength, is
suitable for all applications. Producer also guarantees lifetime of at least 150
insertion cycles (exchanges of a sensor).
