FIRST STEPS as Modeline Computers Ltd.

We recognized the possibility of a standard windows platform for thermal validation requirements to meet the diverse needs of HTM2010 reporting and produced version 1 TQSoft™ (then called LOGSYS) with drivers for Anville, Yokogawa, Eurotherm, Modeline and Sterimizer loggers. Along with a reporting package called SVR version 1.

The market received these products enthusiastically.


Requirements increased and soon TQSoft™ version 2 was rolled out with extra functions aimed at pharmaceutical requirements as well as drivers for more loggers and calibration equipment.

Then came SVR version 2 which maturity to the HTM2010 reporting package.


Microsoft’s operating system quality, and development tools, continued to improve and resulted in TQSoft™ version 3. New drivers for the Fluke range, and even Kaye Validator 2000, and TMI-Orion loggers.
