The Monoxor® Plus is the perfect tool for home/safety inspectors, maintenance personnel and HVAC contractors who need to monitor CO in ambient air or stack gases. It has many advanced features, including a trending graph with real-time value displayed, minimum and maximum measured values, and ability to log a 15-minute CO ambient test. The CO sensor is quickly replaced in the field without down time using B-Smart® pre-calibrated sensors. The Monoxor® Plus can also be used to measure ambient and flue gas temperatures, using optional thermocouple accessories. There’s even an available NOx filter to provide more accurate CO readings in flue gas applications.
