Temperature Measurement and Control
1) Adopting high precious armoured platinum resistor, Real-time measure the samples temperature in the tank. Surface with high anti-corrosion coated which can improve the service life time.
2) Temperature measurement range: 0-450℃, accuracy: ±0.5℃
3) Control accuracy: ±1℃
4)The system preset curvature temperature, the maximum preset 8 sections temperature range.
Pressure Measurement and Control
1) Adopting piezoelectric detector, No pressure pipe, no need to contact with samples to avoid pollution.
2) Measurement range:0-20MPa (2500Psi), Tolerance: ±0.01MPa, Sample frequency: 200pcs/s
3) Pressure protection: Microwave emit will automatic stop and alarm when overpressure. 
Operating system
