YOKOGAWA ZR22G, ZR402G split zirconia oxygen/humidity analyzer

Numerical fluctuations: loose wiring, electromagnetic interference, sensor cracks or installation leaks.

Safety and Compliance

（1） Key points for safe operation

Power safety: Confirm that the power supply voltage matches the rated value of the equipment, and disconnect the power before wiring.

High temperature protection: The working temperature of the detector probe reaches 750 ℃, and high-temperature resistant gloves should be worn during maintenance.

Gas safety: Calibration gas/sample gas may be toxic, ventilation or protective mask should be worn during maintenance, and the pipeline should be checked for leaks.

Sensor protection: The sensor is made of ceramic material to avoid impact and pressure, and direct contact with water droplets is prohibited.

（2） Compliance and Disposal

Identification compliance: CE/UKCA certified products must comply with the importer requirements of the corresponding region.

Waste disposal: Equipment must be disposed of in accordance with local environmental regulations; Batteries (lithium manganese dioxide batteries) need to be classified and recycled (EU/UK region).

Document compliance: The copyright of the manual belongs to Yokogawa Electric and cannot be copied or disseminated without permission.
