Principle of Galvanic Battery Type/Zirconia Type Oxygen Concentration Meter
In Tekune Measurement, we handle two types of oxygen concentration meters based on the principles of galvanic cell and zirconia methods. 〇 Galvanic Cell Type The lead anode performs an oxidation reaction, assisting the reduction reaction at the cathode. It behaves as if combustion is occurring at the anode due to oxygen, generating current, which is why it is also called a fuel cell type. PPM models: 2010BX, 2001RS, 2001LC, 1000RS % models: 210BX, Oxtron, 201RS, 1100BE, 201LC 〇 Zirconia Type It compares an unknown process gas with a known reference gas using the Nernst equation. The sensor measures the electromotive force to determine the oxygen concentration. Examples of PPM models: 4100, 7100, etc. Examples of % models: 111, 5100, etc. For more details on the principles of oxygen concentration measurement, please refer to the URL below.
To ensure safety checks in areas with a risk of oxygen deficiency and to secure the safety of workers.
Measures oxygen concentration from 0 to 25 vol%. Can be continuously used for approximately 15,000 hours with two AA alkaline batteries. Three lineups to choose from based on cord length. Large LCD screen for easy visibility. Equipped with an automatic air adjustment function that automatically adjusts to 21.0 vol% after power is turned on. Alerts with sound and lights, while simultaneously illuminating the LCD screen's backlight. Complies with JIS T 8201:2010 for oxygen deficiency measuring devices.
