Moreover, the meter offers 10,000 data memory, auto and manual data logging, Auto Stable, Auto Hold, and Real-Time measurement modes. As a result, the WQ-310 DO-K gives users a practical solution for water quality monitoring, wastewater analysis, aquaculture, environmental testing, and industrial water control.

Features

• The Horiba WQ-310 DO-K measures dissolved oxygen from 0.00 to 20.00 mg/L for various water quality applications.
• Moreover, the meter measures oxygen saturation from 0.0 to 200.0%, making it useful for environmental and treatment process monitoring.
• In addition, the oxygen range from 0.0 to 50.0% supports broader oxygen-related measurement needs.
• The meter provides 0.01 mg/L and 0.1% resolution, so users can read measurement results clearly.
• Furthermore, the accuracy of ±0.2 mg/L and ±2% supports reliable DO testing in routine applications.
• The automatic salinity compensation uses a conductivity sensor, while manual salinity compensation allows adjustment from 0.0 to 40.0 ppt.
• Additionally, the automatic barometric pressure compensation uses the built-in barometer, while manual adjustment supports 10.0 to 199.9 kPa.
• The meter supports up to 2 calibration points, helping users maintain reliable measurement performance.
• The temperature range from -30.0 to 130.0°C supports sample temperature monitoring during testing.
• The push-pull connector helps users connect the sensor securely and conveniently.
• Moreover, the ABS/polycarbonate body material supports durability for field and laboratory use.
• The 10,000-data memory stores measurement results with date and time stamps for better traceability.
• In addition, auto and manual data logging help users record data according to their testing workflow.
• The Auto Stable, Auto Hold, and Real-Time measurement modes support flexible operation in different testing conditions.
• The programmable calibration alarm from 0 to 400 days helps users manage calibration schedules more easily.
• Finally, the programmable auto power-off function from 0 to 60 minutes helps save battery power during field operation.
