HK-258A Portable Micro Dissolved Oxygen Analyzer Introduction: The measurement of the HK-258A portable micro dissolved oxygen analyzer is based on electrochemical polarography (Clark electrode). The instrument consists of a meter and a probe (sensor). It features high measurement accuracy, fast response speed, compact size, and easy operation. It is mainly suitable for the detection of low-concentration dissolved oxygen in ultrapure water and can be widely used in various industries such as power, petrochemical, and steel. Features: 1. High sensitivity: resolution up to 0.1μg/L 2. Fast response (T90): not exceeding 22 seconds 3. High speed: Measurement can be completed within 3-5 minutes 4. Lightweight and portable: The entire device weighs 300 grams 5. Low power consumption: continuous operation for 1500 hours 6. No need for preheating: Measurement can be made immediately after power-on 7. Humanized design: Magnetic stickers everywhere 8. Long maintenance cycle: electrode maintenance every 6-8 months Technical Specifications: Detection range: 0.1μg/L~20.00mg/L Resolution: 0.1μg/L Zero error: not greater than 1.2 μg/L Response time (T90): not exceeding 22 seconds Temperature sensor: NTC thermistor, with a measurement accuracy of 0.1℃ Compensation function: Automatic temperature compensation; manual setting of atmospheric pressure and salinity Temperature of the measured medium: 0~50℃ Sample flow rate: 150-500mL/min Power Supply: Four AAA alkaline batteries Operating duration of the handheld device: not less than 1500 hours Working environment: Temperature: 0-45℃; Relative humidity: not exceeding 90% Overall dimensions: Instrument: 164mm (length) × 75mm (width) × 17mm (thickness) Weight: 300g (including instrument, probe, and flow cell)
