TP251 portable dissolved oxygen analyzer Introduction: The continuous measurement method for DO is the diaphragm electrode method. Its diaphragm is composed of polytetrafluoroethylene fibers, polyethylene, etc., with platinum as the positive electrode and aluminum and lead as the negative electrodes. The two metal electrodes are immersed in an electrolyte solution, and the electrodes and electrolyte solution are installed in a small room with an aerobic semi permeable membrane. Connect the current measurement circuit, and the molecular oxygen in the water diffuses to the electrode surface through the diaphragm, causing an electrode reaction. When the electrode parameters are constant, the stable diffusion current is directly proportional to the oxygen concentration in the water sample at a certain temperature. The TP251 portable dissolved oxygen analyzer has a Chinese display and Chinese menu guidance, making it easy to operate. It has the characteristics of multiple functions, high measurement accuracy, and convenient portability. Suitable for measuring trace dissolved oxygen in solutions of various industries. Features: 1. Advanced SMT technology and integrated design, high integration circuit design is stable and durable. 2. Advanced microcontroller technology, high performance, low power consumption. 3. The electrode response time is short, making it convenient for sewage measurement. 4. 24 bit A/D signal acquisition, high measurement accuracy, accuracy and reliability. 5. Chinese main menu operation, easy to understand, fast and convenient to operate. 6. Data cyclic storage function, automatically clearing overflow data, simple and convenient operation, with a power outage data storage time of more than 10 years. 7. The continuous use time is long, and it can be measured for up to 8 hours when fully charged. 8. Small and beautiful appearance, easy to carry. Technical parameters: Display: 128 × 64 LCD, Chinese display Measurement range: (0-20.00) mg/L Accuracy: ± 1.5% FS Resolution: 0.01mg/L Repeatability: ≤ 1% Response time: T90<5min (25 ℃) Environmental temperature: (5-45) ℃ Water sample temperature: (5-45) ℃ Power supply: AC (85-265) V frequency (45-65) Hz Power: ≤ 1W External dimensions: 80mm x 30mm x 175mm Weight: 0.26kg
