UEPL History

UEPL started as a new R & D laboratory at UPL premises with a couple of employees in the year 1993 with a well drawn out plan to develop initially phosphine detection devices and extend the technology to other gases. Encouraged by the initial success on developing phosphine detection devices the Lab. was shifted to the present premises in the year 1996 with a new name Chemo Electronic Laboratory (CEL). CEL made rapid progress and developed instruments and detector tubes for a large number of gases and started marketing the products by the year 1997. By 2010 the CEL became a self supporting unit with more than 100 employees and CEL was renamed as Uniphos Envirotronic Pvt. Ltd. (UEPL) and became a private limited company.
