1200-B Combustion Test Kit |
Includes
portable Dwyer Magnehelic© Draft Gage with large 4" dial
instead of No. 171 Inclined Draft Gage, 0 to .25" W.C.
range in .01" divisions. Accurate within 4% of full scale.
Also has air velocity scale with 800 to 2000 F.P.M. range.
No leveling necessary; no gage oil required. Kit is otherwise
identical to No. 1200-A, Weight only 7 lbs. 5 oz. Optional
kit available with 0 to 0.5" or 0 to 1.0"W.C. Magnehelic© AV
Gage; contact Dwyer.
Optional: On special order,
the portable Dwyer No. 460 Air Meter may be substituted for
the No. 171 Inclined Draft Gage. The Air Meter has a direct
reading dual scale with high range of .05" to 1.0" W.C. and low range of .005" to .09" W.C.
Low in cost, it also has air velocity scales with total range from 260
to 4,000 feet per minute. |

Guesswork
does not pay. Kit includes this easy-to-use Dwyer Slide
Rule Computer. It gives you and your customer visual proof
of heating plant efficiency.
The Dwyer Combustion Test Kit
is quick and easy-to-use. With it, you can measure all four
factors that govern overall efficiency: CO2,
content, draft, stack temperature and smoke. Accuracy to ± %
CO2, fully meets the requirements of the professional
Heating Engineer. Yet an apprentice can follow the simple,
illustrated step-the-step instructions. |
| |
CO2 CONTENT: To
a large extent, the efficiency of a boiler or furnace depends
on the amount of air supplied to the combustion chamber. Too
little air causes smoke. Too much air wastes heat up the stack.
Testing fuel gases for CO2 content gives you an
instant, exact measure of combustion efficiency. A high CO2 reading
- 8% to 12% - shows high efficiency. A low CO2 reading
indicates low efficiency or too much air. The Dwyer CO2 Indicator
reveals the situation accurately.
SMOKE: As you adjust a clean fire toward
a higher CO2 reading, you will reach
the smoke point. By inserting filter paper in the
intake of the Dwyer Smoke Gage Pump, you can take
a sample and match it with the Smoke Chart included.
The chart facilitates balancing the burner for
maximum CO2 with minimum smoke. While
conforming with ASTM D-2156-XX standards for distillate
fuel smoke density, this Smoke Gage can also effectively
test any gas or wood burner.
DRAFT: The Dwyer Draft Gage furnishes a
continuous reading of the draft and instantly shows
the slightest change as you make adjustments to
increase efficiency.
STACK TEMPERATURES: Quickly determined with
the Dwyer Stack Thermometer included.
THE RESULT A DEFINITE EFFICIENCY
RATING: When you have finished checking
the installation you will have raised the CO2 content
as high as possible without causing a smoking fire … you
will have the draft control set to provide about
.02" or .03" water draft over the fire … and
you will have a stack temperature of about 500° to
600°F. At this point, you transfer the first
and last of these figures to the Dwyer Computer
and read out the percentage of efficiency - accurately
and dependably. *Before checking as or coal-fired
units, consult local codes.
Air Velocity Measurement Too!
|
| |
| By adding
a small pilot tube, which will fit into the kit case, air velocity
measurements can be taken in heating, ventilating and air conditioning
installations with the gages furnished. The Magnehelic Gage
and No. 460 Air Meter have dual scales calibrated in inches
of water and in feet per minute for air velocity. A conversion
chart can be used to quickly convert velocity pressure indicated
on the No. 171 Draft Gage to air velocity. |
