Amphenol SGX-4OX Galvanic Electrochemical Oxygen Sensor

规格

Product Introduction

The SGX-4OX is an industrial oxygen sensor designed for use in portable gas detectors. It provides reliable measurement of oxygen concentration in the range of 0 to 25% by volume. The sensor operates on an electrochemical principle and delivers a linear output signal proportional to the oxygen level. It is engineered for long-term stability and durability in demanding industrial environments.
