Characteristics, function and service life of systems and components are influenced by varying thermal and climatic conditions during transportation, storage and use. Tests therefore have to be carried out in order to safeguard and optimise product quality. Our temperature and climatic test chambers set standards with regard to ease of operation, performance and equipment.

We offer environmental simulation technology for all things automotive. Standard testing and customised test systems for corrosion and weathering, electrical, electronic and mechanical components and systems of all sizes and design capacities for motors and emission tests.

High product reliability is a basic requirement for today’s competitive market and is often the only difference between the various manufacturers. The reliability of electronic products can be substantially improved by the use of environmental stress screening (ESS) techniques to minimize the risk of errors and failures of products and simultaneously improve the reputation of a company.

Our salt spray test chambers and climate alternating test equipment allow selective and reproducible accelerated corrosion testing in accordance with the national and international standards including DIN, ISO, ASTM, DEF and MIL-STD.

The goal of emission tests is to detect and determine the concentration of undesirable substances, which are released by materials and components of all kinds. These tests have become standard in contemporary safety assessment and quality control. Weiss offers systems for qualitative and quantitative emission analysis of volatile hydrocarbons from featherweight fabrics to evaporation and exhaust emissions of heavyweight vehicles.

We are leading in the development and manufacturing of Stability Test Systems and for long term testing of pharmaceutical- and cosmetic products. Our extensive range of climatic chambers from 34l to 200m³ includes all necessary documentation possibilities as well as a the complete support for qualification and calibration.

Our product range comprises specialised test systems including the simulation of exposure to weather, formaldehyde, EMC and ATEX testing in research, development, quality control and production. Reach-in test chambers and walk-in test rooms are designed, produced and installed in accordance with client needs.

Our range of Fitotron® plant growth and insect research equipment offers unsurpassed accuracy and reliability in the control of temperature, humidity and lighting. We provide small-scale, off-the-shelf chambers through to multiple units and customised, 100% fit solutions for bespoke projects.

The system control software Simpati enables optimum operation of your environmental simulation and oven systems for performing tests in the fields of research, development and production. The operation of test systems becomes easy and time-saving. The integrated monitoring routines enhance the reliability of the systems.

These sturdy drying ovens are suitable for variety of heating and drying processes in production and research. The Votsch Heat Technology products have become the Weiss Heat Technology brand products.
