Jim Mills, MD of Air
Monitors, says: “Environics
products are renowned
around the world for quality,
accuracy and reliability; good
quality calibration is key to
the delivery of good quality
data from gas detection and
monitoring systems.”
Environics gas mixing and
dilution technology is based
on very precise control of
thermal mass flow controllers,
which normally offer accuracy
of ±1% of full-scale flow.

When combined with
Environics technology, this is
improved to ±1% of setpoint
which, says the company, can
produce a 10-fold
improvement in accuracy.
