†Accuracy and uniformity at 100°C. Rise Time in minutes to 200°C. Tests
run with empty oven and minimum exhaust. Performance will vary with
load, exhaust rate and application. See Bulletin TC-920
for additional details.

Standard Temperature Control Systems MP SERIES
Microprocessor temperature control system provides the unmatched accuracy, precision
and convenience of microprocessor technology. Proportional temperature control
ensures accurate temperature regulation. Digital set guarantees repeatable settings
and a large digital temperature display indicates oven temperature. A platinum
RTD monitors and responds instantly to the temperature of the workload. Optional
programmable control (ramp/dwell capability) and timer are listed below.
For over-temperature protection, a second control system consisting of an independent
hydraulic thermostat, set by the operator to a temperature slightly higher than
the set point, provides a mechanical back-up should the microprocessor fail.
A red panel lamp signals an over-temperature situation.
Additional Shelves,
25 lbs distributed load per shelf, 75 lbs maximum oven load; specify oven
model when ordering.
Programmable Temperature
Controller, microprocessor based, digital indicating, 4 programs of 8
ramps and 8 dwells, ramp rate in °C per minute, specify maximum dwell
of either 999.9 minutes or 999.9 hours when ordering, in lieu of standard
controller Option MPTC
