Enerac - Model 942 -Combustion Efficiency Computer

Plus, only 942 offers a second display of carbon monoxide content in one part per million (ppm) increments ranging from 0 to 1999 ppm.

These two readouts, working in tandem, make safe boiler tune-ups simple. Maintenance personnel observe changes in both readouts as fine-tuning adjustments are made until optimum savings and acceptable CO levels have been reached. It`s a simple 5-minute procedure that quickly pays for itself with fuel savings from 3 to 15 percent and increased plant safety.

A system so reliable, it`s practically fool-proof.
Since ENERAC 942 performs all the necessary calculations automatically with computerized accuracy, tricky conversion charts used by more rudimentary test kits are no longer required. This rugged solid state unit also eliminates the need for hand pumps, shattered glass, and imprecise color matching charts. As a result, you can obtain accurate, reliable results with virtually no operator training time required.

It`s also a CO monitor.
As your all-in-one CO monitor, the ENERAC 942 can be carried throughout the physical plant for area CO safety checks. A flashing light triggers automatically when OSHA`s 8-hour weighted average limit of 50 ppm CO has been exceeded. A recorder output permits permanently recorded measurements.

Unmatched versatility In a compact, portable Instrument.
Housed in a sturdy drawn aluminum case, the ENERAC 942 is battery operated, weighs just 10 lbs., and is considered carry-on luggage that fits easily under your seat or in the overhead compartment. It computes efficiency for 5 standard fuels (coal, #2 and #6 oils, natural gas, and LPG), or you can substitute other optional fuels. ENERAC 942 comes complete with a condensate trap and a special in conel probe capable of withstanding temperatures up to 2000°F. Feature for feature, no other instrument combines so much versatility and dependability with such easy portability. ENERAC 942 - it`s the one, and only, piece of combustion testing equipment you`ll ever need.
