Advanced Combustion Analyzer For Commercial Boilers and Furnaces
Description
The UEi ACA is our first combustion analyzer, which is backed by UEi Service
The ACA features a new high-contrast graphic display, a new flue probe with integrated pressure readings, an H2 compensated 10,000 ppm CO sensor with purge pump protection, and wireless probe connection for use with optional wireless pipe clamp probes.
ACA allows techs to print to an optional printer through the IR port for hard copies or wirelessly to a compatible device using the KANE LIVE App to record and email results.
Features
Ambient CO2 readings to test building IAQ
Integrate optional wireless probes
CO over-range pump protection from high CO levels
High-contrast graphic display
