SOX500 Zirconia Oxygen Analyzer

Oxygen transmitter parameter requirements

Display: Oxygen concentration, tube temperature, tube voltage, output current, sensor internal resistance, self-diagnostic information, etc.

Operational Language: Chinese (English optional)

Power Supply: 220VAC ±10%

Power Frequency: 50/60Hz

Heating Power: ≤150W

Measurement Range: 0.01%-25.00% (adjustable from 5.00% to 25%)

Output Signal: 4-20mA

Signal Interface: Supports RS485/MODBUS protocols

Bluetooth Port: Expandable Bluetooth functionality available in the menu

Damping Adjustment: Adjustable damping coefficient in the menu

Measurement Accuracy: ±1% of range or ±0.1% of reading (O2)

Constant Temperature: 700.0°C ±0.2°C (adjustable from 500°C to 900°C) Protection Rating: IP66

Calibration Mode: Manual calibration/fully automatic calibration, selectable via the menu (automatic calibration requires an automatic calibration unit).

Data Retention: Output hold function during calibration.

Auto Purge: An automatic purge function is available in the menu to automatically purge dust from the filter at regular intervals.

Mounting Method: Wall-mounted.

Span Drift: Drift should not exceed 0.2% of the adjusted span over a 12-month period.

Stability: ≤±0.05% (instrument under 4-hour continuous calibration).

Self-Diagnostics and Alarms: Self-diagnostics are available, including thermocouple reverse connection, thermocouple burnout, heating anomalies, oxygen concentration alarm, and temperature alarm.

Response Time: 90% response within 0.5 seconds (measured from the moment gas enters the calibration gas inlet and the analog signal begins to change).

Oxygen Transmitter Service Life: ≥5 years
