|The UK Medical Devices
Directive, in common with most National Regulatory Bodies,
requires measuring devices to be checked every year
(aneroid devices need to be checked every six months).
The specification of the greenlight
is that taking into account the worst case tolerance
of all components and the range of environmental conditions,
only 1 in 10,000 devices would need any form of recalibration
In practice we believed that it would
be much better, and experience has now confirmed this
enabling us to offer an extended warranty on the calibration.
We deliberately chose expensive good quality components
to achieve this, as our goal was to give clinical
staff assurance that their instrument was accurate
and would not need the added expense of frequent recalibration.
cycle tests were carried out to show compliance
with the relevant standards.
The greenlight 300
has been validated to the New International Protocol
of the European Society of Hypertension by the Mayo
Clinic in the United States, giving further independent
proof of its accuracy and suitability as a replacement
for the mercury instrument. The greenlight
300 is also sold as a test reference manometer for
checking aneroid devices – another indication
of its reliable accuracy.
For hospital and institutional customers
who are planning replacement of their mercury devices
we are able to offer trials with the greenlight
The greenlight 300 is available through
our network of distributors, and supply or further
