Guardian Plus CO2 monitor
A low-maintenance carbon dioxide (CO2) monitor has been introduced for monitoring and controlling atmospheres in enclosed areas.
Designed for wall mounting, Edinburgh Sensors' Guardian Plus continually monitors CO2 levels in enclosed areas where concentrations may exceed safe levels. Installation is recommended in breweries, fermentation rooms, transport containers and poorly ventilated working areas. Other applications include food processing, safety monitoring, combustion processes, landfill, exhaust emissions, energy management, incubator and horticulture control, atmosphere control of greenhouses, mushroom farms and plant growth chambers, monitoring indoor air quality and optimising air conditioning efficiency.
The unit monitors CO2 from 0-1000 ppm to 0-100% and displays gas concentrations on an easy-to-read LED panel. An alarm function activates when pre-set concentrations are exceeded.
It uses a dual wavelength NDIR design incorporating two filters and a matched twin element detector. This technique provides long-term measurement stability because variations of instrument signal levels, resulting for example from source ageing or optical contamination, are inherently compensated for, since both the sample and reference channels will be affected equally and therefore will not change the ratio.
The unit is gas specific and does not exhibit cross sensitivity with other gases, it does not interact with the gas being measured and hence does not consume anything, and cannot be 'poisoned' by high concentrations of gases.
