WQA-680P Portable Multi Parameter Water Quality Meter IP67 Titanium Housing 60 Hour Battery

WQA-680P Portable Multi Parameter Water Quality Meter

The WQA-680P is a field portable multi parameter water quality meter built for river, plant and aquaculture measurements in tough conditions. The upgrade cycle focused on three customer complaints about earlier portable meters: readings that drifted, slow stabilisation, and housings that cracked after a season of field use.

Higher Accuracy Than Previous Generation

• pH accuracy improved to plus or minus 0.01 pH, with a low-drift glass bulb and automatic temperature compensation from 0 to 50 degrees Celsius.
• Conductivity accuracy of plus or minus 0.5% FS through a four-electrode cell that resists polarisation in high-salinity samples.
• Dissolved oxygen accuracy plus or minus 0.1 mg/L with salinity and barometric pressure compensation entered or read automatically.
• Three-point automatic calibration with buffer recognition reduces operator error when several technicians share one meter.

Improved Instrument Performance

• Stabilisation in about 1.2 seconds, so a full seven parameter set takes seconds instead of minutes in the field.
• Up to 60 hours of continuous use per charge, covering a multi-day sampling trip without a power source.
• 50,000 reading memory with time stamp, exportable over Bluetooth 5.0 to a phone or tablet for immediate site reports.
• One-hand operation with backlit keys and a large sunlight-readable display, usable with gloves in cold or wet conditions.
• Electrode slope and battery diagnostics displayed on screen before a measurement session.

Upgraded Materials and Construction

• Titanium alloy shell replaces the previous ABS housing: lighter, stronger and fully corrosion resistant in brackish and chlorinated water.
• TPU over-mould absorbs impact, and the meter survives a 1.5 m drop onto concrete.
• IP67 sealing survives accidental immersion, so a meter dropped into a tank can be retrieved and dried without internal damage.
• Armoured TPU cable with strain relief at both ends resists the cable breakage that ends the life of most portable meters.
