Innovative-Developing Enterprise "Calmet" Ltd. was founded in 1989 by designers from Calibrators Laboratory of Lumel's Research & Development Centre. It was arisen for meet the needs of designing, production, selling and servicing a new kind of calibrators and electric equipment testers. Name Calmet derive from words CALibrators and METrology - the main action's field of Calmet company. For several years, about 70% of our sale has made export, mainly to EU and Asia countries. Topic of export are:
- equipment sold by using our own brand Calmet,
- special order realized projects,
- equipment sold by using brand of other companies.
Equipment designed and produced by us, are used in many laboratories all over the world using brand many different companies or our own Calmet as well. It is possible thanks to our big experience in designing, production and servicing of new electronics and computers technology devices.
Traditionally we specialize in electrical power quantities generating – calibrators of voltages, currents and power. Since 1996 we have also busy with testing electricity meters and power network parameters analysing – meters testers, standard meters and connected with them network parameters meters. Since 2002 we have involved in generating and measuring network quality parameters - calibrators, network quality recorders and analysers. Since 2006 we have been also interested in automation of electro-utility automatic protective equipment testing - relays and modern digital protection.
We work according to ISO 9001:2015 Quality System
Commentary to our history.
We are an innovative-developing company and from the beginning developmental department makes a half of our personal staff, that is why every year we put into practice new products. Moreover, for 1999-2012 we have designed and produced power network parameters meters, electricity meters testers and network quality analysers, ordered by international companies using their brand.
Innovative-Developing Enterprise "Calmet" Ltd. was called into being for developing and producing a new kind od calibrators and testers – this task we have realized up to this day by using modern electronics and computers technology, thanks to that since many years we are mainly an export company

Three phase calibrators are the most complicated kind of calibrators, require the best qualifications during designing and production – they are showcase of the company. It is possible, that it is the main cause, why such few companies all over the world produce three phase calibrators, and why is such high export of them.
