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.

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.

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.

Clever functions like this give you more information for easier

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.

test results are dis-

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

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.
