The NMA1 Smart Combustion Analyzer brings complete combustion analysis into a single, smartphone-like tool built for technicians who need fast, reliable readings in the field. Its lightweight, gun-style probe and vivid 5-inch HD touchscreen make setup and operation intuitive, while onboard sensors for O2, CO, flue gas temperature, and differential pressure deliver a full combustion picture — including calculated CO2, efficiency, excess air, and flue gas loss — without the need for a separate manometer. The NMA1 connects wirelessly via Bluetooth to the myNAVAC™ and measureQuick® Apps, letting technicians monitor readings hands-free remotely and log up to 1,000 records for professional job documentation. With a rugged design rated for tough jobsite conditions, a lithium battery with quick charging, and support for all major fuels and system types, the NMA1 is built to keep pace with a full day of service calls. Every unit ships with the accessories needed to get to work right away, backed by a 2-year device warranty and a 4-year sensor warranty.
The NMA1P delivers everything the NMA1 offers — full O2, CO, flue temperature, and pressure sensing, smart app connectivity, and a rugged, hands-free design — bundled with NAVAC’s NPR1 wireless thermal printer for technicians who want printed proof of performance on the spot.
