Welcome to the Website of the IAS GmbH
Your partner for HovaCAL calibration- and vaporizer units
Our core competences
A precision test gas starts with the dosing of liquid and gas. The type of fluid determines the appropriate dosing method: volumetric, gravimetric or thermal. The main factor is always the traceability to a primary method.
Evaporation must be complete and even. If evaporation is incomplete, the vapor concentration is too low. If it's uneven, so is the concentration gradient over time. Our evaporation systems are precisely adapted to these requirements.
Gas analysers should ideally be checked using a test gas that is similar to a sample gas. In particular, if humidity is a significant component of the measuring gas, it cannot be neglected during testing, either. This is accomplished through dosing and evaporation of aqueous solutions with the HovaCAL®.
We are specialists in our field!Our company develops and manufactures precision equipment for generating gas-vapor mixtures for a wide range of applications. Therefor we combine our unique evaporation systems with various methods of liquid and gas dosing. This allows our units to evaporate different liquids over a very wide dosing range. This results in the generation of continuously streaming and high-precision gas-vapor mixtures, which can be used both for gas analysis and in process engineering.
Hydrogen chloride, hydrogen fluoride, mercury compounds, ammonia etc. – Where these critical test gases of critical components are required, the HovaCAL® calibration gas generator, the centerpiece of our product portfolio, has established itself as a standard tool for testing emission monitoring systems.
In addition to our standard products, HovaCAL®, HovaGAS and HovaPOR, we also develop and manufacture customer-specific systems for all areas of gas analysis.
