Online multi-parameter controller
Online multi-parameter controller
Feature:
Ten-inch high-definition LCD industrial touch screen display multiple parameters at the same time: ORP、 residual chlorine, pH、 turbidity, temperature
Touchable screen keys, one key switch parameters, graphs, query history data, easy to operate.
Wireless SIM card connection, remote computer monitoring, mobile phone APP real-time query.
Instrument uses high-precision signal acquisition and amplification circuit, extremely high measurement accuracy, good stability.
pH automatic temperature compensation, automatic identification of standard liquid, convenient calibration, accurate test parameters.
Residual chlorine, automatic / manual pH、 temperature compensation, small range sensor detection parameters more accurate.
The turbidity digital electrode, use reset settings and use without calibration.
ORP digital electrode, easy calibration, strong anti-interference and fast response.
Parameter setting according to the screen prompt, the operation man-machine interaction, simple and convenient.
In-machine LCD backlight can be set according to the environment or operation time, more humane.
Three roads relay output control, can automatically alarm or with the dosing pump and other peripherals for automatic water quality control.
Two analog control signal outputs, external control circuit and equipment.
Restore factory settings to avoid data reset after misoperation.
Watchdog setting ensures that the instrument does not crash during use.
IP65 protection grade, waterproof, moisture-proof, dustproof to ensure the service life of the instrument.
According to the ISO9001 of this instrument The 2015 quality management system requires production, and before leaving the factory after strict testing and correction, to meet the requirements of the specifications.

Residual Chlorine accuracy |
When the pH value is between 5.0-7.2 and constant, the residual chlorine accuracy ±0.03 mg/L or 3%, whichever is greater(Under constant pH test, pH within the error range of±0.2） |
||
|
When the pH value is between 7.2-8.5 and constant, the residual chlorine accuracy ±10%(Under constant pH test, pH within the error range of±0.5） |
|||
|
When the pH value is between 8.5-9， the residual chlorine accuracy ±20% |
|||
|
When the pH is greater than 7.2, it is not suitable to test the low residual chlorine value; When the pH is greater than 9, the test value will be inaccurate |
|||
|
When measurement below 0.10 mg/L, the concentration error can not be calculated by percentage;When DPD test error, the error is calculated by ±0.03 mg/L. |
