as appropriate, to your current needs. Plug and play will ease maintenance time
and cost, and the intelligent modular system will remove the need to calibrate
each sensor. Additional i-modules can be purchased, pre-calibrated from your
local supplier.
Reliable, anti-shock mechanics and robust housing
The Tetra 3 housing is built from resilient material, giving it strength and flexi-
bility to withstand the hardest of working conditions, water and dust tight to
IP65 and IP67, and with a non-slip grip. The case has been carefully designed
to make servicing easy and at the same time very rugged. If the unit is dropped,
there will be no disruption of power or function, ensuring reliability and service
for years to come.
Software
The processes used to design and develop the Tetra 3 software ensure a high
degree of reliability and robustness. Thus Tetra 3 has been designed to be a truly
reliable personal gas monitoring system. The internal circuitry includes an exter-
nal watchdog, where the software monitors for any malfunction within the unit
and will display an error warning to the user should they occur.
