main feature
Chinese display, Chinese menu, Chinese note: using the menu structure, similar to the microcomputer operation, the operation is simple, the entire operation steps Chinese tips, can not be manual, you can easily complete.
Multi-parameter on-screen display: Displays residual chlorine, temperature, pH, output current (HOCL or residual chlorine input current), status, and time on the same screen.
Historical curve: The secondary residual chlorine measurement data is automatically stored every 5 minutes, and the residual chlorine value can be continuously stored for months. On the same screen, it provides two functions: "history curve" display and "timed fixed point" query.
Notepad function: Notepad faithfully records the operating conditions of the instrument and the alarm occurrence time for easy management.
Monitoring electrical function: Each calibration method, time and results are recorded to facilitate the query and analysis of electrical changes.
Digital clock function: Provides a time base for various functions.
Excellent display method: Use a 192 × 64 dot matrix LCD display with backlight to achieve graphic and Chinese display. Adjustable uniform background light, clear observation in dark outdoor conditions.
Instrument stability does not crash: Watchdog program to ensure that the instrument does not work in a continuous job.
Manual current source function: Check and arbitrarily set the output current value to facilitate the detection of the recorder and the lower computer.
The software sets the current output mode: the software selection is 0~10mA or 4~20mA output, without the user dialing any switch.

Measuring principle and electricity3.1 Measuring principle:
Electrolyte and osmotic membrane separate the electrolytic cell from the water sample. The osmotic membrane can selectively allow ClO- penetration; there is a fixed potential difference between the two electricity, and the generated current intensity can be converted into residual chlorine concentration;
On the overcast: ClO- + 2H+ + 2e- → Cl-+ H2O
On Yang: Cl- + Ag → AgCl + e -
Since there is a fixed conversion relationship between HOCl, ClO- and residual chlorine at constant temperature and pH, residual chlorine can be measured in this way.
3.2 residual chlorine:
2058-1 On-line residual chlorine, adopting the principle of permeable membrane, selectively allowing ClO-penetration and measuring the concentration of HOCL. Before use, it needs to be connected to the meter for activation for half an hour to stabilize. 2058-1 On-line residual chlorine, direct measurement of HOCL concentration.
Electric life of 2 to 3 years, the electric film head can be replaced, electric film head model: 2058-3. Change the membrane head every six months. The electrolyte is a special solution and added every three months. Electrolyte Model: 2058-4. Every time you change membranes or add electrolyte, you need to recalibrate the electricity.
The temperature electricity is already installed in the residual chlorine electricity, so there is no separate temperature electricity.
3.3 pH electricity
2058-2 On-line pH, using two complex pH electrodes to measure the pH of the sample. The residual chlorine concentration was calculated from the pH, temperature, and HOCL concentration.
