WQA-8800B Laboratory Multi Parameter Water Quality Analyzer 0.001 pH Resolution PEEK Flow Cell

WQA-8800B Laboratory Multi Parameter Water Quality Analyzer

The WQA-8800B is the upgraded generation of our laboratory multi parameter water quality analyzer. It was redesigned around three priorities requested by our laboratory and utility customers: more accurate measurement, higher overall instrument performance, and upgraded materials in every wetted part. One bench unit covers eight parameters, so a single sample run replaces several separate instruments and reduces operator error.

Higher Accuracy Than Previous Generation

• pH accuracy improved to plus or minus 0.002 pH with 0.001 pH resolution, allowing reliable readings at the low-ionic-strength range where older meters drift.
• Conductivity accuracy improved from plus or minus 1.0% FS to plus or minus 0.5% FS through a redesigned four-electrode cell and a 24-bit analogue front end.
• Five-point automatic buffer recognition with simultaneous temperature compensation keeps calibration valid across a 5 to 45 degrees Celsius working range.
• Turbidity resolution reaches 0.01 NTU with an 860 nm infrared source, so low-level changes near the drinking water limit remain visible.

Improved Instrument Performance

• Dual-core processor with a 7 inch colour touch screen, giving stable readings without the display lag common on single-chip meters.
• Eight parameters measured in one sample cycle with a typical stabilisation time below 15 seconds.
• 200,000 data sets of internal memory with time stamp and GLP record, exportable as CSV through USB-C or Bluetooth 5.0.
• Continuous self-diagnosis of electrode slope, cell constant and lamp intensity, with an on-screen reminder before a calibration expires.
• Built-in 12,000 mAh battery supports a full working day of bench operation without mains power.

Upgraded Materials and Construction

• PEEK flow cell replaces the acrylic cell used previously: chemically resistant to acids, alkalis and most solvents, and stable at temperatures where acrylic deforms.
• Sapphire optical window on the turbidity channel resists scratching and staining, keeping the optical path clean after years of abrasive samples.
• 316L stainless steel sensor bodies with PEEK sleeves resist corrosion in chlorinated and saline water.
• Spill-resistant PEEK deck and sealed keypad protect the electronics from routine laboratory spills.

Technical Specifications

Typical Applications

• Drinking water plants: routine compliance testing of pH, turbidity and residual parameters
• Wastewater treatment laboratories: influent and effluent quality control
• Environmental monitoring stations: surface water and groundwater sampling
• Food and beverage factories: process water and CIP solution verification
• Pharmaceutical and electronics plants: purified water quality checks

Calibration and Maintenance

Electrodes are replaceable individually, so a single worn sensor does not require replacing the whole probe set. Standard buffer solutions, conductivity standards and turbidity standards are available as a matched kit. The instrument stores the last ten calibration records for audit purposes.

Ordering and Support

Standard configuration includes the analyzer main unit, sensor set, calibration solutions, USB cable and operation manual. Custom probe lengths, extra parameters, local language interfaces and OEM branding are available on request. Our technical team supports method setup, calibration training and after-sales spare parts supply.
