Our Gold Standard Accuracy +/- 3mmHg Sphygmomanometer
The greenlight 300 has been developed to provide a reliable and accurate alternative without mercury. This is achieved using silicon chip technology replacing the traditional mercury column with an electronic pressure detection system.
Validated to the ESH International Protocol by the Mayo Clinic. It is also sold as a test reference manometer for calibrating and checking aneroid devices – chosen by leading pharmaceutical companies for their testing services in the UK.
The alternative to mercurial options
There is a risk of toxic effects when mercury is spilt, meaning mercury sphygs must be handled with care, health and safety measures must also be in place to deal with spills appropriately. Increasing concerns about mercury contamination have led many people to look for a mercury alternative. The difficulty has been finding an accurate, reliable alternative and concerns have been expressed by many experts about the replacement of the mercury sphyg in clinical practice with potentially less accurate devices.
Overcoming problems associated with other types of sphygmomanometer: it is non‑toxic, robust and most importantly, automatically self-calibrates to zero when switched on, thus ensuring reliable accuracy.
The traditional mercury display is replaced with LEDs clearly displaying pressure in steps of 2 mmHg, and the clinically important cuff pressure deflation rate is indicated.
