Controls the pressure applied on the ATR crystal during sample analysis. For ATR measurements the pressure is a very significant issue. Too much pressure can crack the ATR crystal and too much low pressure will make no good contact between ATR crystal and your sample. So to avoid that you can set an alarm at a specified pressure with μ Contact Monitor II. The alarm will be triggered as soon as you reach your pre-specified pressure limit.Like this you can apply the desired maximum pressure on the sample for obtaining a high quality spectrum without breaking your ATR-crystal.
