Automated Distillation Tester ad-7

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 tests of petroleum products and samples with narrow boiling ranges. It uses a 10.4-inch LCD with a touch panel for easy and intuitive operation. A Peltier system is employed for cooling/heating the condenser and receiver cylinder compartment—a robust design for continuous use.


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


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


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