Multiple safety measures:
1.High pressure exterior vessel: PSF exterior vessel with PPS liner, maximum pressure endurance is 6MPa (900 psi).
2.Overheating protection: when the case or the exterior vessel is overheated, instrument will warn and suspend the microwave radiation
3.Abnormal noise detection: when abnormal noise is made in the furnace chamber, instrument will warn and cut off microwave automatically.
4.Abnormal pressure warning: a unique device of ‘optical fiber non-contact displacement sensor’, real-time monitor and control the pressure in the digestion vessel, display every vessels’ pressure change by screen. Independently monitor each vessel’s reaction situation, avoid overpressure caused by single sample’s too violent reaction. Pressure auto matching control and rise speed limitation, when the pressure is much too high or the rise speed is too fast, instrument warns and cuts off the microwave output.
5.High strength bursting framework and design of dual protective door, effectively assure the safety of operator.
6.Dual pressure reduction by inner vessel’s air bleed hole and bursting film: when the gas pressure in the digestion vessel is too large, gas will leak from the air bleed hole; when the pressure is larger than the limit value and the hole can’t leak the air in time, the skirt border of the sealing bowl will broken, then leak gas and reduce pressure.
7.Double security door
