The 1261
Calorimeter
l
(
A self-contained oxygen bomb
calorimeter with automatic
microprocessor control for rapid
and precise calorific tests with
minimal operator attentIon.
RECOtv1NIENDED FOR
Coal mine, coal preparation plant, commerCial
inSpection, coal burnmg utility and other Industnal
laboratorIes where calorific tests of SOlid, liqUid or
refuse-derlved fuels are run dally on a routrne basIs,
and where rapId tests wIth good repeatability are
reqUired. Although pnnc/pal uses for the 1261
CalOrimeter are found In coal laboratories, It has
equally Important applicatIons for determining the
calonfic value of other solid and liqUId fuels. FIrms
involved In waste disposal management find the
1261 Calonmeter a reliable means for mOnltonng the
energy content of refuse fuels. Equally Important
applicatIons are found In food laboratorIes for
determining calonf/c values for foodstuffs and animal
feed mIxtures, In university laboratones for teaching
purposes and for high preCISion energy research
proJects.
A COMPLETE, SELF-CONTAINED
OPERATING UNIT
All sensors, controls and Jacketing In the new Parr
1261 Isoperlbol CalOrimeter are bUilt Into a single,
compact cabinet to proVIde a self-contained
operating Unit consisting of:
• A temperature-controlled, insulating water Jacket
wIth a bUilt-In clrculatrng system and an electriC
heater
• An oval calOrimeter chamber and bucket.
• An 1108 oxygen combustIon bomb
• A bUllt-m automatic system for charging the bomb
with oxygen
• A hIgh preCISion electrOniC thermometer.
• A sealed, touch-panel keyboard for data entry
and operation control.
• A bnght, LED display for operator promptmg,
status indication, data vertflcatlon and report
review
FULLY INTEGRATED
MICROPROCESSOR CONTROL
All steps In the test procedure are managed by a
microprocessor control system usmg third generatIon
hardware and software pre-programmed to.
• Operate the calOrimeter 10 eIther the conventional
Isopenbol/eqUlllbrlum mode or In a faster
isoperlbolldynamlc mode.
• Monitor and control the Jacket temperature.
• Ascertain equilibrrum, fire the bomb, confirm that
ignitIOn has occurred and monitor the
temperature nse.
• TermInate the test wlthm operatmg parameters
selected by the user and check for errors.
A BUIIJ:IN MICROCOrvIPUTER
All data involved In a calonflc test IS handled
automatically by a dedicated microcomputer which
Will:
• Accept and store all sample weights and
temperature data.
• Apply all necessary corrections for aCid, sulfur
and fuse.
• Compensate for any added combustion aId or
"spiking".
• Compute and report the heat of combustIon In
Units selected by the user.
• TransmIt test results to an alpha numeric printer
(not mcluded with the calOrimeter)
• Accept sample weights dIrectly from an analytical
balance usmg an appropnate Interface.
• Communicate With and transmIt calOrifIc data to a
central computer and/or other instrumentatIon In
a Smart Link network.
