K29300
High Temperature Evaporation Loss Test Apparatus
Performs evaporation loss tests on lubricating greases at temperatures of up
to 600°F (316°C). Maintains sample temperature within ±0.3°F while passing
heated air over the sample surface at a controlled flow rate. Consists of
evaporation cells and aluminum block oven with controls for sample
temperature, air temperature and air flow rate. Evaporation cells include
grease sample cup, head, eduction tube, cover and thermocouple tube. Aluminum
block oven provides efficient response and safe operation at high
temperatures. Microprocessor temperature control has °C/°F switchable digital
setpoint and display. Operator and equipment are protected by an
overtemperature control circuit which automatically interrupts power to the
unit when bath temperature exceeds a programmed cut-off point. Microprocessor
PID control provides quick temperature stabilization without overshoot and
the bath is protected by an overtemperature control circuit that interrupts
power should bath temperature exceed a programmed cut-off point. Dual LED
displays provide actual and setpoint temperature values in °C/°F format.
Communications software (RS232, etc.), ramp-to-set and other enhanced
features are available as extra cost options. Separate air preheater controls
and flowmeters for each cell permit accurate control of heated air flow to
sample surface. Order accessory Digital Thermometer (Cat. No. K29310) to
monitor exit air temperature and ASTM 3F or 3C Thermometer for block (sample)
temperature. Accessory oil sample cup (Cat. No. K29530) converts evaporation
cell for lubricating oil samples.
