Seitron Novo 4N Combustion Analyzer
The Seitron Novo 4N is the next evolution in combustion analyzers providing precise, reliable, and quick analysis for residential and commercial HVAC Technicians. The Novo 4 is designed to make combustion analysis quick and intuitive. The Seitron Novo 4N portable combustion analyzer features a 7” touch screen for easy menu navigation, a 4-year O2 sensor, an integrated water trap with LED backlight for easy maintenance, new dual-range (low/high) sensor technology, and a CO protection dilution pump. The Novo 4 flue gas analyzer includes an O2, CO, NO, and NO2 sensors. The Seitron Novo 4-N does not include a printer. If you would the Novo 4N with an integrated printer, the part number would be Novo 4N-P. Another option would be to order a separate thermal printer with a Bluetooth connection (p/n AAST04). Made in Italy.
The Seitron Novo Combustion Analyzer comes with different sensors and, with or without a printer, options available are listed below.
Each Novo Combustion Analyzer comes standard with O2, CO and NO gas sensors. The difference between all the 4 gas models is which 4th gas you select, including the NOVO-4N (NO2), NOVO-4S (SO2) or NOVO-4C (CxHy).

Overview
Touch screen
The large 7” touchscreen display on the Seitron Novo 4N grants maximum visibility of all information along with quick and smooth browsing experience. The screen shows all the metrics related to the measured parameters with the ability to change between data, graphic, and advanced mode. The combustion graph in the advanced mode allows the user to see in real time how tuning affects the HVAC system. In addition, the new and intuitive interface allows the user to quickly customize combustion reports, choose the displayed order of the gases measured, set and/ or change the parameters of the device, and carry out multiple optional measurements, plus more.

Pro Analysis Mode Feature
The Seitron Novo Combustion Analyzers now feature the new Pro Analysis Mode, which displays in real-time the measurement data on a combustion guide and stoichiometric chart to make analysis even easier.
How does it work?
- Select Fuel Type & Equipment Type (80% Boiler, 90% furnace, water heater, etc)
- Watch & Stabilize your Combustion readings in the GREEN Zone for optimal combustion
- View Stoichiometric Chart/Graph
- Print or Email the results
Probe Connection
Seitron has changed the connection of the Novo 4N combustion analyzer sampling probe. Instead of three separate connections for temperature, draft, and flue gases on the analyzer, the new connection has been redesigned to just one simple connection. The new connection is an easy plug-n-play design that allows the user to easily connect the probe.
The Seitron 4N flue gas analyzer includes manometer hoses to simultaneously check and /or adjust the gas pressures of the equipment. This allows an HVAC technician to measure combustion parameters and gas parameters at the same time - reducing service time and limiting the need for several devices.


New Dual Range Sensor Technology
The Novo 4N has eliminated the question of whether you should use a high or low range sensor. The Novo flue gas analyzer detects gas concentration and automatically adjusts the scale, ensuring the sensor life and the measurement resolution. The Seitron Novo-4N includes a long-life O2 sensor, CO/H2 sensor plus a NO sensor. The new generation of long-life gas sensors enhances the reliability and accuracy of measurements. In addition, the Novo analyzer includes a dilution pump which helps protect the CO sensor from high gas concentrations that might otherwise damage the sensor. Seitron does have other sensor options available upon request (SO2, CxHy, H2S, NH3, CO2-IR, CH4, H2). Please contact customer service regarding the optional sensors.

Water Trap
The redesigned water trap is now integrated on the Seitron Novo-4N to guarantee maximum performance and easy maintenance. The large inspection window with a backlit LED allows the user to quickly and easily check the water level and filter at any time.

Novo Housing
The Novo gas analyzer has an updated rubber housing which offers a rugged modern design and a sturdy grip. The analyzer also includes integrated magnets on the back for hands-free operation.

The Seitron Smart Analysis App
You can use the Seitron Smart Analysis App (iOS and Android) to communicate with the analyzer in REAL-TIME using Bluetooth. From there you can create reports and email data to anyone.
- perform Automatic or Manual analysis remotely
- view the analysis data in real time
