  • Add alkaline and/or acid, distilling and titrating, titration cup waste discharging, calibrating, fault detecting, solution level monitoring, and calculating can all be realized fully automatically.
  • Titration color can be calibrated both automatically and manually. The titration endpoint is judged by the color signal collected by the high accurate 16-bit 3-primary-color digital signal color sensor.
  • 2.0μL high-precision titrating system and professional unibody precision-work plunger are the assurance of the determination accuracy and operation reliability.
  • Not-in-position prompt of security door and digestion tube.
  • The steam pressure is automatically controlled within the safe range, thus danger caused by steam pressure is prevented.
  • Alkali pump adopts high-reliable PTEF bellows pump, which is anti-corrosion and anti-partical-plugging, stable during liquid adding, and free from the danger cause by negative pressure suction.
  • Water-saving design: Real-time monitoring of the circulating cooling water flow rate, warning reminder whenever the water pressure is lower than it is supposed to be.
