Quick Overview

UEi C157 Eagle 3X Combustion Analyzer with EOS uses an electro-optical sensor (EOS) to measure CO2 levels and then uses this value to calculate O2 levels and improves upon the 2X by adding an NO sensor. The EOS sensor uses optical readings that keep the sensor from physical contact with the gas, thus prolonging its life greatly. UEi C157's use of this sensor as well as an extended life CO sensor and elimination of a standard of O2 sensor makes the cost of upkeep on the unit much lower than others. This model includes Flue Probe, IR Printer, (2) K-Type Temp Probes, (2) Static Pressure Hoses, (1) True Draft Probe, Gas Tap and Hose, AC Adapter/Charger, Hard Case, (2) Printer paper rolls, (2) Particle filters, Batteries.

Customer Reviews

well built Review by Carl Hopkins

Its nice that UEi puts a rubber boot and magnetic back on their analyzers. Nice to be able to just put the analyzer on a unit and work hands free. Sometimes you need to walk away while a test is running and there is not always a convenient place to put your meter.

Cant complain Review by KingBud

Great sensor warranty that makes this a no brainer. I do like the backlit LCD display, a small thing, but being a tool i use almost every day it makes a difference to me.
