The TPI Flue Gas Analyzer with NOX is an all in one instrument designed to maximize diagnostic efficiency and accuracy.

Features:

• Measure O2, CO, and NO
• Calculate CO2, NOX, efficiency, excess and air ratio
• Will work with high efficiency furnaces, hot water heaters, and other
  combustible gas appliances
• Dual input K-type thermocouple temperature tester
• Dual input differential manometer with 3 selectable units of measure:
  kPa, mBar, inH2O
• Protective rubber boot
• Soft carrying case
