In the table you can see which countries have received one or more Respicond.

26 machines have been sold to date (April 2005) since Feb 1993, when the company Nordgren Innovations AB (Ltd.) was started.

The work on Respicond started 1980 and operational equipment has existed since 1983. Respicond was developed to fulfill a scientific need and the customers, so far, are researchers in many countries all over the world.

In Creswick, Australia a special version of Respicond V has been installed. It has a much greater depth and can contain vessels tall enough for 25 cm soil cores. They have locally constructed the vessel with the large diameter. In charge is Dr. Stephen Livesley Scientist (GTU), Forest Science Centre, Water Street, Creswick, VIC 3633.

History

Click to enlarge

Respicond III as an aquarelle. This version of Respicond had a DOS program and was based on a Wheatstone bridge. The lids with handles turned out to be virtually impossible to lean against anything. They slid along the floor and scattered around.
Work on this equipment started 1980 and operational equipment has existed since 1983. The earliest versions had glass conductometric cells and platinum plates horisontally attached to the bottom of the glass beaker. It used analog printers and a ruler to manually measure the decrease in conductance. The first really useable instrument had 24 vessels in two small water baths and a DOS program.


The production group

In addition to A. Nordgren Innovations AB, headed by Dr. Anders Nordgren, that developed, markets and coordinates the production of the Respicond instruments, a number of small companies participate in the production. We have all connections to Umeå University or the Dept. of Forest Ecology, Forest faculty of SLU, (the Swedish University for Agricultural Sciences) situated in Umeå, Sweden.

The electronics is designed and manufactured by LL Electronics, Rönnliden 39, SE937 96 Bygdsiljum a village ca 70 km from Umeå. This business is run by Lars Lundmark, who is an invaluable research engineer at the Department of Analytical Chemistry, Umeå university.

The production of the water bath and all the vessels with the conductometric cells is manufactured by Tojo Forest Technology at the small village Djäkneboda 35 km north of Umeå. Tojo Forest Technology is run by Torbjörn Jonsson, earlier at the University of Umeå.

The program is created by Lars Lövdahl heading LL Technical Software and research engineer at the Dept. of Forest Ecology, SLU, Umeå.
