TO2-238-T PPM Oxygen Sensor (H2S Resistant)
The TO2-238-T PPM 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 principal and is manufactured in house under a strict quality procedure. The sensors are self contained and minimal maintenance is required – no need to clean electrodes or add electrolyte. The precision sensors offer excellent performance, accuracy and stability while maximizing the expected life.
The sensor is capable of measuring oxygen from 0.01 parts-per-million up to 25.0%. For maximum life and performance, we recommend to use it when monitoring oxygen from 0.2 ppm to 1000 ppm with an occasional upset or air calibration.
The TO2-238-T uses our acetic acid electrolyte. This sensor is designed for optimal performance in acid gas applications such as CO2 and Natural Gas. These sensors are limited on shelf life, we do not recommend storing for over 3 months.
The TO2-238-T is designed to be H2S resistant up to 500 PPM for the life of the sensor. This is due to a unique filter element that is put in front of the sensing membrane.
The output and dimensions of the TO2-238-T is designed as a drop in replacement for competitive analyzers. Simply remove the competitive sensor and replace with an SSO2 sensor.
Varying performance advantages to the SSO2 sensors can be attributed to minor modifications in dimensions, connections, and packaging. However, the principle of operation and the basic components remain the same.
