a&p instruments | Company building

a&p instruments is a recently formed company emerging from ULTRA X laboratory devices, a traditional family-run business.
Besides standard moisture analysers, a&p instruments’ main focus is the production and distribution of instruments for special applications.

Here, ULTRA X’s years of experience are put to good use.
In December 2002, the move to a new building and thus to modern, well-equipped facilities, enabled the company to take another step forward.

Our efficient organisational structure means that since 2004, we have been providing quick delivery times of less than a week, while maintaining our consistent high quality and prompt service.

Annegret Ukena

Annegret Ukena is general manager of a&p instruments. She is also head of the technical purchasing and development departments.

Mrs Ukena is the granddaughter of the well-known inventor of the moisture analyser, August Gronert.


In 1925 the engineer August Gronert founds his company and produces equipments for drying agricultural product. He owned a lot of international patents and his brand name was ULTRA X.
After the second world war in 1950 he established a new company in Western Germany and there he developed the first infrared moisture tester (pic 1). It was a combination of a very precise mechanical balance and an infrared drying lamp. This principle was so genious and also simple that up to now some ULTRAMAT devices (pic 2) of the 60th are still in use.All moisture balances in the world work after the principle of drying and weighing at the same time.

In 2001 ULTRA X stopped the production and some former employees found their new company a&p instruments.
The main products are produced further in our new location in Detmold, new devices are developed and the brand ULTRA X is still in use.

So a&p instruments offers all ULTRA X customers the full service for their instruments and is able to provide them with necessary spare parts for every ULTRA X device of at least the last 10 years.
