Designer and manufacturer of gas detection equipment, Edinburgh Sensors has produced the Guardian NG infrared gas monitor range.
Its continued commitment to research and development in principles such as non-dispersive infrared (NDIR) has, says the company, contributed to several major advances in sensing of gases such as CO, CO2, CH4, CF4 and SF6.
These advances are evident in the wide range of gas monitors and original equipment manufacturer (OEM) gas sensors, including the Guardian NG instruments, which have been supplied to clients worldwide.
The Guardian NG infrared gas monitors are designed to provide near-analyser quality, continuous sampling, measurement and display of target gas concentrations for either CO2 or CH4 gases, where detection level ranges of between 0 – 3,000 ppm and 0 – 100% by volume are required.
Other features include a graphical display of historic readings, possible over a user-defined period, and the ability for data to be transferred via an on board RS232 I/F – with optional Ethernet I/F and relay outputs for control of external devices.
The Guardian NG wall-mounted monitors are designed to be easy to install, offering long-term stability plus low maintenance.
Monitors can detect gases from sampling points up to 30 metres away, using the built in sampling system, says Edinburgh Sensors, plus a LCD display with digital alarm set-point controls and password protection has been integrated to prevent accidental or deliberate change of settings. These are housed in robust plastic IP54 rated enclosures to prevent the ingress of particulates and water.
The Guardian NG DC infrared gas monitor also offers near-analyser quality, continuous sampling, measurement and display of CO2 concentrations between 0 – 3,000 ppm by volume but from low voltage DC (18-30V) supplies.
The Guardian NG instruments are suitable for a wide variety of applications including process control, biogas, personal safety, indoor air quality, horticulture, brewing and agriculture.
