Description

Portable Polarized Dissolved Oxygen Meter – Single Parameter (DDO10)

PRIMARY CLINICAL & DIAGNOSTIC USES

1. Rapid Assessment of Dissolved Oxygen in Biological and Environmental Samples

Primary Use: Provides a portable, single-parameter dissolved oxygen meter utilizing polarographic probe technology to measure DO concentration (0.00~20.00 mg/L) and oxygen saturation (0.0~200.0%) in aqueous samples, with integrated temperature, barometric pressure, and salinity compensation for accurate readings.
How it helps: For the clinical laboratory scientist and environmental health specialist, the DDO10 enables rapid, on-site determination of dissolved oxygen levels in various aqueous matrices relevant to healthcare environments, such as purified water systems, dialysis water, and biological oxygen demand (BOD) samples in wastewater treatment. The 3.5-inch TFT color screen provides an intuitive, easy-to-read interface for efficient fieldwork. For the patient, accurate measurement of dissolved oxygen in water used for dialysis or other medical processes is a critical parameter for ensuring water quality and preventing adverse events related to improper water treatment.

2. Monitoring of Water Quality in Critical Healthcare Systems

Primary Use: Designed to monitor dissolved oxygen levels in purified water systems, water-for-injection (WFI) loops, and wastewater treatment facilities associated with hospitals and pharmaceutical manufacturing.
How it helps: For the facility water quality manager and infection control officer, the DDO10’s IP57 dustproof and waterproof rating, along with its rechargeable lithium battery and Type-C charging, makes it ideally suited for spot-checking water quality at various points in a distribution system. The auto-calibration and data storage functions support rigorous quality assurance documentation as required by GLP standards. For the patient, continuous and accurate monitoring of water treatment processes helps prevent healthcare-associated infections linked to waterborne pathogens.

SAFETY HANDLING PRECAUTIONS

1. SAFETY PRECAUTIONS

Electrical Safety: Do not immerse the meter in liquid, despite its IP57 rating. Ensure the Type-C port is dry before charging. Avoid pulling the probe cable violently.
Probe Handling: The polarographic probe is delicate. Do not touch the membrane with sharp objects or abrasives. Do not use the probe in solutions containing organic solvents that might damage the membrane.
Polarization Time: To ensure accuracy, DO probes require a warm-up period of at least 10-30 minutes after connecting to the meter to stabilize the current. Connect the probe and turn on the meter well in advance of calibration.
Calibration Intervals: Calibrate the meter daily before use or as per facility protocol, especially when high accuracy is required for critical water systems. Use air calibration for general purposes.
Membrane Cap Life: Replace the membrane cap when it is damaged or when the response time becomes sluggish.

2. FIRST AID MEASURES

Electrolyte Exposure: If the internal electrolyte solution (DO filling solution) comes into contact with eyes, flush with copious amounts of water for at least 15 minutes and seek medical attention. If on skin, wash with soap and water.
Sample Splash: If a biological sample splashes into the eyes, flush with water for 15 minutes and seek medical attention; if on skin, wash with soap and water.
Electrical Malfunction: If the meter shows signs of electrical malfunction, disconnect it from any power source and contact service personnel.

3. FIRE FIGHTING MEASURES

Flammability: The plastic housing, cable, and case are combustible; may melt or burn if exposed to flame or high heat.
Extinguishing Media: Use carbon dioxide (CO₂) or dry chemical extinguisher for electrical fires.
Fire Response: Disconnect the meter from the charging cable; do not use water on an electrical fire.
