Precise oxygen measurement depends on a sensor element that fits the gas composition and measuring task. This electrochemical replacement element family gives users two focused choices: GOEL 370 for diving gas, inert gases with high CO2 content and oxygen content below 35 vol.% O2, and GOEL 381 for low oxygen concentrations close to 0.0 up to 100 vol.% O2.
For stable operation in demanding gas applications, both variants use a maintenance-free electrochemical measuring principle with a response time of <10s. GOEL 370 uses an acidic electrolyte, making it insensitive to CO2 gas and suitable for inert gases that are almost exclusively CO2. GOEL 381 uses an alkaline electrolyte and is the preferred option for immersion gas measurements above 35 vol.% O2.
The family supports reliable replacement in compatible Senseca instruments including ECO 410, G 1690 and GMH 369x/GMH 569x. With M16 x 1 screw thread, compact dimensions of approx. Ø 30 x 44 mm and defined sensor signal ranges, it is designed for straightforward integration into the intended measuring setup.
The family provides replacement oxygen sensor elements for compatible handheld and measuring instruments.
GOEL 370 uses an acidic electrolyte, while GOEL 381 uses an alkaline electrolyte for different oxygen and gas applications.
The variants cover oxygen concentration measurement up to 100.0 Vol.-% O2, with recommended ranges depending on the selected element.
The sensor element uses an M16 x 1 screw thread and has compact dimensions of approx. Ø 30 x 44 mm.
Operation is specified from 0 … +45 °C and environmental pressure from 0.6 … 1.75 bar abs.
