Digital Controller. The digital controller is mounted on the roadside countertop and is used to control the
temperature of the Ramsbottom carbon residue tester. The system operates on 110V, 60Hz, single-phase power
supplied by the Ramsbottom carbon residue tester.
Dropping Point Apparatus. This apparatus is designed for use in ASTM test D-2265, D-566, and D-4950 and is
stored in overpack box 3. The apparatus operates on 110V, 60Hz, single-phase power from a convenience
outlet. The apparatus is used to determine the dropping point of lubricating grease. The apparatus consists of a
digital temperature controller, 750W heater, and a test tube assembly with thermometer. The dropping point
apparatus is programmed for a maximum operating temperature of 752F (400C).
Evaporation Loss Bath. The evaporation loss bath is mounted in curbside laboratory cabinet S and protrudes
from the countertop. It operates on 110V, 60Hz, single-phase power supplied by A1CB16, located in the MAIN
POWER PANEL. The unit contains a 1000W heater, temperature controller, stirrer motor, and a thermistor
probe. Maximum temperature is 350F (177C) with a temperature control stability of 1F (0.5C). Refer to
vendor manual for calibration requirements.
Flash and Fire Point Tester. This apparatus designed for use in ASTM test D-92 and is stored in overpack box 3.
It is a fully automatic flash and fire point tester used to examine liquid as well as highly viscous or solid samples
in the same instrument, without any additional equipment. The unit includes an electric heater with sample test
cup and gas flame applicator, Pt-100 probe for sample temperature, ionization sensor for the detection of flash
and fire point, and flame extinguisher. Also included are a stainless steel cabinet, microprocessor electronics
with test programs for flash and fire point, search mode for unknown samples, two individually programmable
test modes, manual ignition test and overtemperature safety cut-off. The apparatus operates on 110V, 60Hz,
single-phase power from a convenience outlet.
Foaming Test Bath. This apparatus is designed for use in ASTM test D-892 and is stored in overpack box 7. It
is a fully equipped constant temperature bath that tests foaming characteristics of lubricating oils to determine
their suitability for high speed gearing, splash lubrication, high volume pumping and other applications. It
aerates the sample through diffuser stone at 94 + 5 mi/min. and maintains sample temperature at 75 and 200 +
15F (24.5 and 93.5 + 0.55C ) for three-sequence testing. It uses precise solid state temperature control with a
thermistor sensor probe. A silent 1/20-hp ball bearing stirrer provides complete circulation to assure temperature
uniformity. The apparatus operates on 110V, 60Hz, single-phase power from a convenience outlet. It has a
temperature range from ambient to 2755F (1345C), controller sensitivity of + 15F (+ 0.55C), and a heater
range from 0 to 1500W. The bath capacity is 9 gal. (38.5 l).
Fume Hoods. The fume hoods are built into the front wall of the laboratory. The exhaust blowers are activated
by switches located on the roadside wall. The fume hood incorporates two vapor proof electrical receptacles.
The glass window moves vertically for access to the interior. Four stopcocks in each unit provide capability for
the use of water supply, water return, air and vacuum. The fume hoods protect the operator from toxic,
corrosive, poisonous, explosive, radioactive, odoriferous, and other harmful and dangerous materials. They
provide an area in which solids can be crystallized by controlled evaporation, and in which heat and steam can
be exhausted. Both fume hood exhaust blowers should not be operated at the same time.
Gas Alarm System. The gas alarm system consists of a main control unit (cabinet assembly) and two remote
detector assemblies. The main control unit is wall mounted on the roadside and connects electrically to the two
detector assemblies. The system operates on l10V, 60Hz, single-phase power supplied by the MAIN POWER
PANEL. The main control unit supplies 5.5 VDC to the detectors. The alarm is calibrated for propane and has a
setting of 20 to 40 percent of the lower explosive limit (lel) of gasoline. An indicating meter in the control unit
shows the concentration being monitored and adjustable dual-level alarm circuits are triggered whenever a
concentration exceeds the lel. The alarm alerts personnel of combustible mixtures that could cause explosions or
cause fires, and automatically activates the air purge system. Refer to vendor manual for calibration
