Standard Temperature Control System
The standard temperature control system for the MARS 6 is the MTS-300 which monitors and controls temperature
conditions inside sample vessels.
A microwave transparent temperature probe is inserted into the thermowell of a sample vessel and connected to a snap-in
port in the center of the roof of the instrument cavity. From there the signal extends to a special temperature control on the
system controller board.
A feedback single from the MTS-300 probe to the magnetron of the system regulates microwave power output to maintain
a selected temperature parameter.
CAUTION
The MTS-300 probe and the thermowell are both fragile. Exercise care when handling either of them.
MTS-300 Temperature Sensor
Optional Temperature Control System
The MARS 6 system is also designed for use with an optional infrared control system. This system is optional for use with
certain vessel sets. With this system, two infrared temperature sensors are located below the cavity floor.
ReactiGuard Cavity Sensing System
The MARS 6 is equipped with an audible sensing system to detect the occurrence of a vessel event inside the microwave
cavity. When an event (such as the venting of a vessel relief device) is detected, an embedded software safeguard
pauses the microwave heating program.
WARNING
Exercise extreme caution while attempting to identify the underlying cause(s) of a detected vessel event.
Proper precautions must be taken to avoid contact with reagents or reagent vapors. Protective gear
should be worn as outlined in the user’s safety program for hazardous materials and the reagent
manufacturer’s material safety data sheet. Refer to these guidelines for proper handling and disposal of
reagents.
Once the cause of the event has been determined, press “Resume” or restart the method.
The function of ReactiGuard is to protect against secondary instrument damage due to an undetected vessel event and
continued heating of released liquids/vapors inside the cavity.
