Modular sensor design
Analyse up to 4 different gases plus pressure and humidity simultaneously In order to adapt gas analysis as flexibly as possible to individual measurement tasks, the single components were designed modularly. This resulted in a »modular system« in which the various photometric components such as detectors, emitters, measuring sample cell, etc. can be assembled user-specifically.
With this sophisticated sensor design, customer-specific applications can be realized without needing a completely new development. The modularity makes replacement and maintenance considerably easier when servicing is required. In contrast to this design, common completely glued gas sensors can only be replaced as a complete unit thus generating high follow-up costs (total cost of ownership) in case of maintenance. Optionally, modules can also be equipped with a sensor for oxygen, pressure and humidity.

تعریف حد تشخیص
حد تشخیص کوچکترین مقدار اندازه گیری است که می توان با عدم قطعیت خاص به دست آورد. این عدم قطعیت شامل وضوح، نویز و پایداری سنسور گاز برای یک گاز خاص و محدوده اندازه گیری خاص است. برای ارزیابی مقدار حد تشخیص، چندین اندازه گیری منفرد در شرایط اندازه گیری یکسان انجام می شود. با نتایج اندازه گیری منفرد به دست آمده، انحراف استاندارد "سیگما" (σ) محاسبه می شود. مقادیر داده شده در جدول برابر با سه برابر سیگما است.
