Concentration values must be typed in on each experiment if is required for the
software to carry out the subsequent calculations.
Conductivity and temperature values will be data logged when ‘GO’ is clicked.
The CEM-MKII Continuous Stirred Tank Reactor can be used with the integral hot
water circulator for operating temperatures above ambient. Alternatively it can be
used with an optional Chiller (CW-17) for operating temperatures below ambient. The
use of the heater or chiller is chosen in the initial menu when loading the CEM
software. When using the hot water circulator the required temperature is set using
the PID controller on the mimic diagram. When using the optional CW-17 chiller the
required operating temperature is set using the thermostat located on the CW-17.
The software automatically generates a series of ‘Watchdog’ pulses that are required
by the CEXC, ensuring that the hardware shuts down safely in case of a software or
communications failure.
