This term stands for „Made in Germany“: comprehensive operation-safety features by instruments (Longlife sensors, CO switch-off, …) and robustness (provided by aluminium housing and aluminium-framed transport cases). 10 Jahre ecom warranty on the aluminium housing and the supply of spare parts reflects our philosophy: not the price but the performance should be the decision-making factor. Their high durability - it is no seldom situation that ecom analysers produced in the 90es are still in operation today – ascertains the investment made in ecom instruments.
