Introduction

Area of application

The OxiQuant B-oxygen meter is used to determine oxygen concentrations in gas
mixtures. It can be used to monitor gas supply equipment in industry and hospitals or
to check breathing mixtures in diving systems (nitrox and trimix mixtures).
Its compact dimensions, low weight, easy handling and calibration make the device
particularly suitable for mobile application.

The OxiQuant B is not designed for personal protection or for monitoring medical
breathing air in direct contact with patients. It must not be used for the preparation of
gas mixtures, but only to monitor them.

OxiQuant B uses an

E

NVITE

C

oxygen sensor, type OOI101-1. This has a rapid

response time, high reliability and stable performance.
