Manual › NDIR evaluation kit 1. General description The kit is designed for thermopile or pyroelectric detectors and IR sources from Micro-Hybrid Electronic GmbH. It is an easy way to evaluate these parts and get started in NDIR gas analysis without developing an electrical circuit and software. The system is flexible, making it possible to optimize the operating parameters for the specific application. This flexibility includes easy control of the IR source and the reading & monitoring of the output data from the detectors. Thus, the development process is accelerated dramatically with...
