Description

The Benchtop Dissolved Oxygen Meter YG1055 is a professional-grade, dual-function analyzer combining high-precision DO measurement (0-20.00 mg/L) with full-range conductivity/TDS/salinity testing—perfect for water treatment plants, aquaculture, and environmental labs. Its 6.5-inch LED touchscreen and intuitive interface deliver real-time data with auto-compensation for temperature, salinity, and pressure.

Key Features:

• Dual measurement modes – Switch seamlessly between DO and conductivity/TDS/resistivity/salinity
• Smart calibration – Auto-recognizes 8 conductivity standards (US/EU/China options)
• Bluetooth & USB data export – Transfer 1,000+ records to Excel or print wirelessly
• Industrial durability – IP54-rated casing, 100,000-press Omron keys, and 12V low-power operation
• Rapid DO electrode – Polarizes in 3-5 minutes with ≤0.1 mg/L residual current

Competitively priced for research and industrial use, the YG1055 outperforms single-parameter meters. Request a quote for bulk or lab pricing!

Frequently Asked Questions (FAQs)

• Can it measure seawater salinity? Yes! Its 0-100 ppt salinity range covers both brackish and marine applications.
• How often should electrodes be replaced? DO membranes last 6-12 months; conductivity cells last 2+ years with proper maintenance (see recommendations).
• Does it include calibration solutions? Solutions sold separately—choose from US, EU, or China standard options.

Advantages and Disadvantages

Advantages

• Lab-grade accuracy – ±0.10 mg/L (DO), ±0.5% FS (conductivity)
• Multi-parameter versatility – Replace 4+ instruments with one device
• Effortless compliance – Timestamped data logs meet EPA/ISO reporting needs

Disadvantages

• No internal battery – Requires 12V/1A adapter (not ideal for field use)
• Bluetooth module optional – Mobile connectivity isn’t standard
• Limited high-range conductivity – Max 2000 mS/cm (K=10 electrode required)

Product Use in the Field

The YG1055 excels in:

• Wastewater Treatment – Monitor BOD, DO, and TDS for discharge compliance
• Aquaculture Farms – Track salinity and oxygen for fish/shrimp health
• Environmental Labs – Test river/groundwater conductivity + DO
• Pharmaceuticals – Verify WFI (Water for Injection) resistivity

Recommendations

• Calibrate weekly using fresh standards for critical applications
• Soak conductivity cells in 3M KCl when not in use
• Pair with a magnetic stirrer for stable DO readings
