testo 320 -
Combustion testing solutions in high def.
Combustion analysis in high definition is more than just a
brilliant display. It’s a combination of proven measurement
standards, contractor-rugged design, and Testo’s innovation.
The result - testo 320 - makes combustion analysis easier to
perform, easier to control, and easier to understand.
The 320 is designed for the job site and for the contractor that
expects more. Use it for basic testing and tuning of all types of
boilers, heater or furnaces. Use it to set up and commission more
complex multi-stage, or modulating heating systems. Combustion
analysis, draft, temperature, pressure, combustion efficiency and
a host of other calculations and functions - all shown in vivid
color. With simple icon navigation, you soon realize it will do
more for HVAC testing.
With the testo 320 you gain more testing flexibility giving you
more customer opportunities and greater profit potential. It pro-
vides all the parameters listed, plus the capabilities shows in the
following pages.

• CO sensors with NOx filter
• Flue Draft, Pressure (vent or duct or switches)
• Temperature (flue & room)
• Combustion Efficiency, Excess air
• Flue Gas Matrix (w/ four user-defined combustion types)
• Oil flow and gas clock BTU calculator
• Memory to 500 readings plus customer site information
• Optional probes for:
- Fine pressure, Gas Leak, Ambient CO2 (IR), Ambient CO air,
draft, pressure, differential temperature
Designed for the job site and the needs of a busy contractor.
The testo 320 gives you a wider measurement range that lets you
test not only controlled or normal combustion applications but
those that have problems. With a CO measurement range up
to 4000 ppm (or optional 8000 ppm) you can test more
combustion appliances.
CO sensor with
The testo 320 eliminates the guess work and provides accurate
readings. Integrated NOx fi lters assure you of the highest
CO measurement accuracy, unlike other analyzers that add the
NOx concentration to the CO measurement displayed. Whether
you are measuring combustion, air free, or ambient CO – you
need to make the decision on a correct measurement.

to the heating system until the cross-hair is “in the green” zone.
Clever functions like this give you more information for easier
adjustments and set-up.
The testo 320 makes your job easier by displaying two to eight
user-defined parameters. With 8 parameters you see all the
measurements simultaneously. No need to scroll up and down
chasing the measurements and double guessing.

Gas leak detection
The gas leak probe
allows you to safely
identify gas leaks. The
results can be stored
and documented. The
test results are dis-
played in ppm.
Draft and Pressure measurement
Critical for proper combustion performance is the draft
measurement to determine if flue gases are flowing correctly.
With the simultaneous flue gas temperature displayed, you know
if the probe is positioned properly. The pressure measurement
gives you the flexibility to test a variety of flow pressures in lines
and switches.
Ambient CO measurement
The 320’s ambient CO function (or optional probe) will display
results graphically and sound audible alarms when levels are
unsafe (user-defined levels). The optional CO probe can also be
used for simultaneous measurement of flue gas and ambient CO.
Magnets on the back of both the analyzer and the printer attach in
a secure and convenient spot. The printout documents the results
with your company’s contact information. This helps to remind
your customer who to call for their next cleaning or yearly service
check. easyHeat software (optional)
can help schedule jobs and print
reports with your company’s logo
for a professional look. The testo
320 combines many combustion
tools into one rugged package for
faster combustion analysis so you
can focus on growing your
business.
Di erential Temperature
This option measures the difference between the outgoing and
return line temperatures. This provides critical information for flow
rate adjustments and
compliance with boiler
specifications.

Hardened cam-lock fi ttings
Provides leak-free operation and greater
test confidence.
Longer lasting sensors
Typically last more than three years.
Sensors are field replaceable and pre-calibrated.
Data management for combustion analysis
An infared printer or optional Bluetooth printer is
available for the testo 320, for printing out
measurement values on site. The testo 320 has
built-in memory that can save up to 500
measurements.
easyheat software option
easyheat software simplifies the management and
archiving of your valuable customer data and
measurement values on a laptop at the job site or on
a PC at home. With easyheat, you can create
customized individual reports.
Additional probes
A wide range of probes enable you to
upgrade at a moment’s notice and gives
you greater customer flexibility.
Simple icon navigation
Simple push button operation with
easy-to-follow menu icons.
Quick drain condensate trap
The sensor’s integrity is protected by
the 320’s condensate trap.
You can transfer your data easily and securely
through the USB port or Bluetooth (factory installed
option) to a PC, printer, or other hardware Thanks to
easyheat software.
