In August 1999 Peter Krogh assumes the position of president and CEO of Ellab A/S.

In July 1999 Hans Jørgen Leo Nielsen resigned as president of Ellab A/S in order to concentrate on the family’s and the foundation´s financial and real estate activities. Hans Jørgen Leo Nielsen continues to serve as member of the board of directors.

In April 1998 Ellab Holding A/S is founded as a fully owned subsidiary of the Ellab foundation. The new holding company is established in order to enable Ellab A/S to focus on its primary business and all real estate and financial activities are transferred to this business unit. At the same time Ellab A/S became a fully owned subsidiary of Ellab Holding A/S. As part of the new setup a new board of directors with recognized professionals was established in Ellab A/S.

In June 1997 Ellab Philippines Corp. is founded.

In 1996 the E-Val system is introduced. E-Val is designed for thermal process validation in the food and pharmaceutical industries. The E-Val system is a cable-based system that consists of modules for real time collection of temperature, pressure, relative humidity, deflection and rotation. The modules are connected in a network that can handle up to 80 channels and the data is collected in a PC-based software for further evaluation.

In 1996 Ellab A/S becomes ISO9003 certified for its production of medical Thermistor probes.

In September 1995 Ellab Inc. is founded in San Jose, California, USA as a joint venture with PHF specialists Inc. Ellab A/S with 75%, is the primary shareholder.

In 1994 Ellab introduces the TrackSense wireless data logger that can be exposed to temperatures from -40 to +140. The TrackSense loggers are uniquely designed with interchangeable sensors for temperature, pressure, relative humidity and rotation. The PC software further allows the logger data to be incorporated with data from the cable based-systems.
PCSOFT92 is further developed into the PCLINK92 software package that can collect data from the CMC821, CTF9004 and CTF9008 cable based systems. Later the same software is used as the basis for the TSSOFT software for TrackSense.

In 1992 Ellab develops its first PC-based system, the CMC92. The CMC92 is designed for thermal process validation in the food and pharmaceutical industries. By means of multiplexing the system could collect real time data from temperature, pressure, relative humidity, rotation and for the first time deflection in the same data files. The PCSOFT92 software package, which runs on a DOS platform, can handle up to 96 channels.

Towards the end of 1991 the CTF84 was replaced by CTF9004/08 a 4 or 8 channel terminal with processor, LCD-display and build-in printer. CTF9004 measures temperature from -100 to +350 degrees Celsius and can work on batteries as well as through mains power supply. The CTF9004 is sold in large numbers to the food industry worldwide and is still actively sold and highly regarded instrument.

In 1991 Ellab introduces its first PC based Pyrogen program, including a relationship database for handling of rabbits and tests.

In 1990 Ellab installs its first metrology laboratory with certified reference instruments for calibration of temperature probes/sensors and recording equipment.

Since the fifties Ellab has continued to improve the quality and precision of its temperature probes/sensors. In the beginning of the 1990’s Ellab develops special probes for advanced research measurements.


In 1985 the HFM86 and DM876 Clinical Monitoring thermometers are developed. These are designed to measure and display 8 temperatures simultaneously, and are used with the unique selection of very accurate thermocouple probes for hypothermia therapy, open-heart surgery, etc. They could also be connected to a computer.

In 1982 the extremely thin flexible 6 and 8-point multipoint probes for hypothermic oncology are introduced. With these it is possible to map the temperatures in a tumour and the surrounding tissues during cancer treatment.

In 1981 Ellab A/S introduces the CMC821, with programmable processor, display and printer, to the food industry. At the time the CMC821 is very advanced and it quickly becomes the industry standard and is sold in large numbers over the next 10 to 12 years.

In 1979 the APT24 with processor is introduced to the medical industry as the first automated Pyrogen test equipment.

In 1978 the Z9CTF is replaced by the very advanced and compact Z4FD, which is capable of calculating F-values on 4 channels and can measure pressure and rotation. The Z4FD can register manually inputted limit values for temperature and F-values. It also has switches so it is possible to control the process according to the limit values.

In May 1978 the Ellab foundation is established and all shares in Ellab A/S are transferred into the foundation. In 1978 came the very thin thermocouple probe A-K20 for measuring in the myocardium during open-heart surgery. It is used together with the DU3-S precision thermometer for monitoring the temperature of patients, flow, oxygenator, etc.

In 1975 the first electronic digital thermometer and Fo-value calculator CTD/FDQ is developed. The sterilization values can now be calculated with a much better accuracy than by the manual method.

In 1973 the first digital thermometers DU-X for remote temperature measurements for intensive care and recovery room patients are introduced. These can be used as single instruments or in a system of up to 10 patients.

In 1971 Ellab introduces the Z9CTF, which is a 6-channel recorder with thermocouple probes. As a world first the Z9CTF is capable of calculating F-values. Z9CTF is sold in large numbers over the next 6-7 years.
In 1970 Elektrolaboratoriet A/S, which now has 40 employees, changes its name to Ellab A/S.

In 1967 a portable and bedside surveillance system for hospitals is launched. This system contains modules for temperature, pulse, respiration rate, blood pressure and recorder and cardio scope for collecting and displaying the data.

In 1965 the company introduces the world´s first temperature recorder TRRD6 based on resistance measurements for medical use. In the following years, the TRRD6 is further developed as the Z8 series with 6 and 12 channels.

In 1961 Elektrolaboratoriet A/S moves to Rødovre just 7 km from the centre of Copenhagen. The company now has 20 employees.

In 1956 TEC – a 4-channel thermometer designed for temperatures between -40 and 130 degrees Celsius is developed for use in sterilization processes in the food industry.

One of the first products is developed in 1950 and named TE3. TE3 is a 2-channel thermometer designed for temperatures between 16 and 45 degrees Celsius. This product is sold in large numbers to customers all over the world for the next 20 years.
