The Sper Scientific Optical Dissolved Oxygen (DO) Meter is an ideal tool for low-maintenance dissolved oxygen measurement. It delivers accurate results even in low oxygen ranges and remains unaffected by acid gases, ensuring reliable performance in challenging environments. With no polarization time or probe maintenance required, this DO meter offers unparalleled ease of use. The large, easy-to-read LCD screen simultaneously displays both dissolved oxygen and temperature, with the flexibility to choose between % and mg/L units for DO measurements. Equipped with built-in automatic temperature compensation (°C/°F), the device also supports manual salinity and pressure compensation for enhanced precision. Additionally, 2-point DO calibration is available, further ensuring accurate measurements every time. Perfect for professionals who need efficient and reliable DO monitoring without the hassle of frequent upkeep. Great for low maintenance D.O. measuring work Remain accurate in low oxygen range and won’t be affected by acid gases No polarization time and no probe maintenance work Large LCD with D.O. & Temperature Display Selectable % and mg/L unit for D.O. Value °C/°F Automatic Temperature Compensation Built-in Manual Salinity and Manual Pressure Compensation 2 Points D.O. Calibration Available The Optical DO Meter's precision and low maintenance design make it a highly versatile tool for a variety of industries: Aquaculture: The Optical DO Meter ensures optimal conditions for fish and other aquatic organisms, with fisheries and aquaculture farms using it to maintain the health of aquatic life.
