Key Applications in Bangladesh

As a premier precision measuring instrument, the MW190 MAX bench meter satisfies stringent regulatory standards across primary Bangladeshi sectors:

• Commercial Aquaculture & Hatcheries: Serves as a vital aquaculture DO meter to monitor oxygenation levels in intensive fish farms, shrimp hatcheries, and pond management systems.

• Textile & Industrial Wastewater Treatment: Essential dissolved oxygen meter for aquaculture and wastewater testing in ETP (Effluent Treatment Plant) facilities across RMG factories.

• Pharmaceutical & Chemical Manufacturing: Ensures strict compliance during formulation processes requiring accurate laboratory oxygen analyzer tracking.

• Food & Beverage Processing: Monitored water purity and oxygen content during production and quality assurance phases.

Maintenance & Buyer’s Tips

How to Calibrate Milwaukee MW190 DO Meter

1. Probe Polarization: Connect the polarographic DO meter probe and allow the automatic conditioning mode (COND) to complete on the dual LCD readout.

2. Zero Calibration: Submerge the sensor tip into MA9070 zero oxygen solution, stir gently, and confirm the offset baseline.

3. Slope Calibration: Expose the probe to air over water for $100\%$ saturation calibration and press accept once stable.

Buyer Verification Guidelines

• Verify Authenticity: Check the serial number and import documentation to confirm genuine Milwaukee MW190 DO Meter Romania origin.

• Membrane Care: Inspect the PTFE membrane cap for stretch marks or air bubbles. Always refill with fresh MA9071 electrolyte solution.

• Sourcing: Always buy from an authorized Milwaukee Instruments importer Bangladesh representative to ensure standard product warranty and support.
