PRODUCT FEATURES
• Measures CO (ppm) & O2 (%)
• Calculates COAF (air free) & EA (excess air)
• Comes with a Water Trap, Particle & NOx filters
• For residential combustion AND / OR ambient applications
• Strong magnet for easy mount on appliances
• Rechargeable Lithium-ion battery via easy USB charger
• Professional aluminum hard-case
• Electronic Pump with Stainless Steel Probe
PRODUCT COMPONENTS
1.
Analyzer - CO & O2 sensors with a niobium magnet for mounting.
2.
Electronic Pump with Stainless Probe.
3.
Hose assembly. 3 feet of silicone tubing, Water trap, particle and NOx filters with
sensor cap. The NOx filter removes cross-interfering acid gases to minimize CO
sensor interference.
4.
Aluminum Hard-case
5.
Screw to mount sensor cap to the Analyzer
6.
USB Charging cable
7.
USB Charger
8.
Analyzer and Pump Aluminum Case

USER TIPS
-
Ensure the analyzer and pump are stored well within specifications.
-
When using the analyzer, condensation may occur and the water trap will
slowly fill with water. Keep track of this. Empty as necessary. Always empty
before storing and retiring the unit after working. Some condensation may
occur in the electronic pump. Run the pump with fresh air to ensure
condensation within the pump has been removed.
-
The NOx filter will last for the life of the detector.
-
The sensors have a rated life of 2 years. If well taken care of, they can last
longer (up to 3 years) but will require more frequent calibration.
-
Please email FORENSICS DETECTORS if any part requires replacement.
-
FORENSICS DETECTORS does not offer sensor replacement. Given the
price point of the detector and cost of the sensor parts, shipping and
calibration, it is simply not economically viable to allow for customer
sensor replacement – and easier to replace the detector. Both pump and
detector can be separately purchased, email us.

1. INTRODUCTION
You have purchased the BASIC RESIDENTIAL COMBUSTION ANALYZER by
FORENSICS DETECTORS. The detector is factory calibrated. This product is a
BASIC analyzer - no frills, simple use, designed to simply get the job done with no
messing around. Turn ON and GO. This detector is made with a robust design
using high quality electrochemical sensors made in the UK. This detector was
made for RESIDENTIAL use for HVAC technicians, contractors, engineers,
energy inspectors, plumbers and others that need to analyze combustion and
flue gases (from natural gas or propane). In addition, the detector can be used
as an ambient air quality detector. The analyzer contains both CO and O2
sensors. The analyzer calculates COAF (CO Air Free) and Excess Air (EA) only
when O2 is less than 20%. COAF & EA equations are calculated as follows:
COAF = (COmeasured x 20.9) / (20.9 - 02measured)
EA% = [[20.9/ (20.9 - 02measured)] – 1] x 100
2. QUICK SETUP
1. Ensure all components included.
2. Ensure analyzer/pump are fully charged.
3. Connect silicon tube with bottom of pump
(pump outlet). Connect pump probe. Attached
sensor cap on the analyzer with screw.
4. Double check all tubing is well connected and
in place.
5. Check water trap, ensure it is empty of water,
if not, open and dry it out.
6. Turn ON pump and detector. When ready to
sample press the ON/OFF button on the
pump and gas will be drawn from the probe
point.
7. Read this manual and familiarize yourself with
the operation of the devices & components.
8. Follow best practices when selecting
combustion gas sample location for
residential appliances. Follow local codes and
appliance manufacturer instructions.
