Microwave heating is very popular for quick and selective digestion of materials in various industries e.g. Food and feed, Pharmaceutical, Chemistry, Environmental, etc. In these application, the sample is mixed into an acid mixture and heated to high temperature, up to 250 or 300⁰C. However, spontaneous heating of acid mixture induces exothermic reaction resulting into very rapid change in temperature and pressure.
Therefore, faster and accurate monitoring of temperature and pressure is crucial in minimizing safety risks. Fiber optic sensors for temperature and pressure measurement have been widely successful in microwave assisted digestion applications due their immunity to electro magnetic field within the microwaves.
• Vessel temperature monitoring increases safety of digestion operation
• Increases lifetime of digestion vessel by direct temperature monitoring
• Programmable temperature limits for starting cooling operation
• Close observations, recording and reporting
• Sample temperature monitoring for highly accurate research analysis
• Precise and automatic sample temperature control
