In this mode, it can also perform the following measurements and tests: Carbon Monoxide (CO) levels, Carbon Dioxide (CO2) levels, Oxygen (O2) levels, CO: CO2 ratios, Excess air temperature, Flow temperature, Return temperature, Differential Temperature, Efficiency, BS7967 CO sweep tests, and CO ambient air monitoring. The Anton Sprint Pro 5 has wireless connectivity, which means that the user can communicate with the analyser from their Android or iOS smartphone as long as they have downloaded the Anton Sprint app. The USB port allows physical communication to the user's PC. The flue gas analyser is operated using large push buttons and an intuitive menu system that can be easily used even when wearing gloves.
