H. Heinz Messwiderstände GmbH

Company information:

Since 1991 H. Heinz Messwiderstände GmbH is developing and fabricating advanced temperature and humidity measurement technology. We offer customized solutions fabricated in both large-batch and small-batch production, or manufactured as individual items. Our engineers advice every customer individually and develop the optimal solution for the customer's measurement problem – from a single sensor up to a complete system.

By forceful modernization of the machinery, our classic assortment of sensor resistors could be extended. Currently, also remittance work in the field of CNC lathe, milling, and drilling is offered.

The company philosophy is focused on

  • high-quality products,
  • comprehensive and competent customer service,
  • continuous extension of our R&D capabilities to satisfy today's and future customer requirements.

Heinz Meßwiderstände GmbH is certified according to DIN EN ISO 9001 since 1995 and according to DIN EN ISO 9001/2000 since 2001, additional ATEX and key account audits.
