ANRI Instruments has announced an extension to the Guardian + range of fixed point gas monitors, Edinburgh Sensor’s Guardian SP.
The Guardian SP is a high accuracy monitor offering increased short-term stability in lower ranges than Guardian + models.
Using an enhanced infra-red dual wavelength sensing head, the monitor offers increased sensitivity and improved short-term noise. As a direct consequence lower gas ranges, including LEL CH4 can be achieved.
Additionally, monitoring of 1000ppm N2O has been added to the range for the first time.
Each unit features LCD display, dual level alarms, analogue output, integral sample pump, and flow fail/fault alarms.
Applications of the Guardian SP include plant physiology, horticulture, fruit storage, leak detection, safety monitoring, ventilation control, landfill, process control, and furnace applications.
