Application
PD W series digestion system is suitable for digestion environmental protection, disease control, scientific research, quality inspection and other fields, rush acid and pretreatment

Features:

  1. stereo surround heating, good uniformity; quality insulation materials to ensure energy efficient
  2. anti-corrosion, acid and alkali, high temperature, easy to clean
  3. large heating area is able to handle multiple samples, temperature uniformity of holes to reach high digestion rate
  4. Advanced handheld pocket PC control and monitoring, wireless communications, remote operation outside the hood to ensure highly secure for operator, also effectively prevent acid corrosion of electrical equipment
  5. 4.3-inch color touch screen programmable temperature controller, a variety of methods to store Class 7, forty segment program control, working time, temperature gradient, the rate is set automatically stop after free intelligent digestion, complete heating process heating, no staff on duty.
  6. Real-time program status display, real-time curve display, to achieve the heating temperature, heating rate and heating holding time controllable.
  7. Dual sensor, heating block and sample solution can be measured simultaneously, more precise temperature control; Or use A sensor measurement sample liquid sensor measuring the highest temperature 210 °C
  8. Atmospheric digestion, reflux hole design to ensure saving about 50% reagent consumption.
  9. Digestion, acid catch, digestion tank volume can be done in one chamber.
  10. Alarm for over-temperature and automatic power-off function
  11. Continues working in at least 48 hours.
