Product Specification

1.OKS-21 Electrochemical Oxygen Sensor Descriprion:

• Measures Oxygen From 0 to 100%

• Electrochemical Fuel Cell Sensor Technology

• Self-Contained, No Need To Add Electrolyte

• Excellent Stability, Performance, & Linearity

• Competitive Drop-In Field Replacement

The OKS-21 oxygen sensor provides high levels of accuracy, reliability, and linearity throughout its measurement ranges. The oxygen sensor is based on the galvanic electrochemical fuel cell principle and is manufactured in-house under a strict quality procedure.

Backed with excellent customer service and an industry proven product design, our sensors excel in performance and quality while reducing the cost of ownership.

Varying performance advantages to the Southland Sensing sensors can be attributed to minor modifications in dimensions, connections, and packaging. However, the principle of operation and the basic components remain the same.

Along with excellent performance and exceptional quality, Southland Sensing offers rapid delivery times to a global customer base for most oxygen sensors.
