Automated Distillation Tester ad-7

Ergonomic, Robust and Versatile

It’s been over 50 years since we started manufacturing automated distillation testers. Nowadays, we deliver to customers in more than 70 countries.

ad-7 automatically performs distillation test of petroleum products as well as narrow boiling range samples. 10.4 inch LCD with tough panel has been adopted for easy and intuitive operation. Peltier system is employed for cooling / heating of the condenser and receiver cylinder compartment. Robust design for continuous use.


  • 10.4 inch (*) Color LCD. * 4 times larger than previous model
  • Intuitive operation by Touch Panel
  • Advanced data management software; TDAS (Tanaka Data Acquisition System)



  • Fire Containment System: Heater shuts down when ultraviolet sensor detects a fire, and CO2 gas flows into the heater compartment (if connected to CO2 source).
  • Flask Catcher reduces the risk of breaking vapor tube of flask.
  • Overheat protection: Heater shuts down automatically at the upper end of the temperature scale.



  • 200 test modes
  • 5,000 test results
  • RS-232C, USB port, Ethernet
