Additionally, the meter can store up to 200 sets of data, including readings, temperature, and time, which can be retrieved and managed efficiently via USB connection.
Tablet-Type Dissolved Oxygen Meter uses a polarographic DO (dissolved oxygen) electrode to measure the concentration of dissolved oxygen in liquids accurately. This type of electrode operates based on the principle of electrochemical reduction, where oxygen diffuses through a membrane and is reduced at the cathode, generating a current proportional to the oxygen concentration. The polarographic design ensures high sensitivity, fast response time, and reliable performance, making it ideal for precise and consistent DO measurements in both laboratory and field settings.
Our Tablet-Type Dissolved Oxygen Meter is well-suited for field use, due to its durable and user-friendly design. It features a large 5-inch tablet-style LCD with a 150° wide viewing angle, ensuring clear visibility even in bright or challenging lighting conditions. The built-in rechargeable battery provides up to 30 hours of continuous operation, making it reliable for extended field use without the need for frequent charging. Additionally, its compact build and automatic electrode recognition enhance convenience and efficiency during on-site measurements. With a rating of IP54, the meter is resistant to dust and water splashes.
Labtron’s Tablet-Type Dissolved Oxygen Meter comes with essential standard accessories to ensure seamless operation and accurate measurement. It includes a DO electrode for precise oxygen level detection in various samples. A filling solution to maintain optimal electrode performance. The temperature probe to measure accurately measures the temperature of the samples, ensuring correct compensation and reliable results. Additionally, it comes with a power adapter to meet the device's electrical requirements for consistent and stable performance.
