Oxygen gas transmitter OxyTrans I KF

electrochemical2-wirefuel cell

Overview
The OxyTrans I KF is an electrochemical oxygen analyzer for trace and percent measurements (ppm and %), designed for flow-through applications with a KF40 connection. It features an easy-to-read LCD, one-point calibration and an industrial-grade sensor suited to continuous monitoring.

Applications

• Process gas monitoring
• Inert gas control
• Vacuum systems and leak testing
• Semiconductor, laboratory and industrial installations

Measuring ranges
Selectable ranges from 0–10 ppm up to 0–100% O2; custom ranges available on request.

Sensor
The unit uses a fuel-cell (electrochemical) sensor that provides high sensitivity, linear response and long operating life for both trace and percent measurements.

Calibration
Trace-range calibration should be performed with an appropriate calibration gas at a chosen concentration within the measuring range. Percent-range calibration can be performed with ambient air.

Features

• Compact flow-through design
• Cost-effective for continuous monitoring
• Long-life electrochemical sensor
• IP65 enclosure for industrial environments
• Reverse-voltage protection and temperature compensation

Flow-through measuring cell in Stainless Steel

• Modular stainless-steel measuring cell
• Replaceable components allow repair of the cell without replacing the complete unit
