Affordable, Best-In-Class Portable Combustion Analyzer

Fyrite® Tech - Residential Combustion Gas Analyzers

Busy technicians and boiler contractors who need to ensure safe operating conditions, determine combustion efficiency and perform emissions testing rely on Bacharach’s PCA®3.  This lightweight handheld instrument is the industry’s first advanced portable combustion analyzer with a full color graphic display for superior visibility and user-friendly interface.  Super bright backlighting, zoom display feature, dimming mode function and the most sensor configuration in its class provides the user with best-in-class instrumentation.  In addition to the included Oxygen (O2) and Carbon Monoxide (CO) sensors, the PCA®3 can be ordered with CO (high), Nitric Oxide (NO), Nitrogen Dioxide (NO2) and Sulfur Dioxide (SO2) sensors or the sensors can be added in the field without down time, using the B-Smart® pre-calibrated sensor options. 

PCA®3 is designed for on-demand or semi-continuous sampling of light industrial, institutional, commercial and residential furnaces, boilers and appliances.  With sturdy metal gas and draft connectors and rugged construction plus simple operation and maintenance the PCA®3 is the new workhorse of the industry.

Bacharach's unique B-Smart® Sensor Exchange Program will deliver new B-Smart® Sensors right to the user. Just a simple "pop out and pop in" replacement of the sensor permits self calibration with no gas or guess work required! Providing the quickest and easiest calibration options to date, the B-Smart® Sensors assures accurate performance with no downtime.
