CODCr (Chemical Oxygen Demand) ON-LINE MONITORING INSTRUMENT
WD2100 CODCr (Chemical Oxygen Demand) ON-LINE MONITORING INSTRUMENT has unique patent technology based on the air pressure transmission optimization, which realized on-mechanical sample delivery, made mutual independent among circuit control, sample handling unit and inspection unit, reduced mutual interference, improved its running performance.
Closed loop feedback dual wavelength mixed detection technology resolved the problems of zero drift from photoelectrical detection equipment at mainland and abroad at present, improving the accuracy of COD online inspection analyzer, easy to use, simple operation.
High precision measurement of the quality of pump patented technology, effectively solve the peristaltic pump is the prevalence of the rolling wheel assembly and the inner wall of the pump body are adjustable gap of technical difficulties, the realization of a small dose of the high precision quantitative mixed reagent; and reduced reagent usage; improve the service life; ensuring the measurement accuracy.
l Sample pretreatment patent technology made samples in the function of homogenization, filtering, removing some suspended matters, loss from COD filtering and preserving over-proof samples.
Applying advanced hybrid mode operation, realizing high-accuracy, high stability and on-time measurements on CODCr value.
FEATURESl Calibration: range and zero point (calibration and blank calibration) and calibrated by manual and automatic operation.
l Auto-cleaning: dealing with equipment, sampling pipe, instrument pipe, valves and other parts before twice auto-cleaning at the beginning and ending of measuring.
l Defensive Function: self-protection when it in the situation of power outage, water-break and auto-restored function.
l Auto-alarm: Auto-alarming on the condition of system fault, power outage, short of sample and distilled water, other abnormal inspected data, alarm signal data above can be transferred to remote control network.
l Remote Control: both-way communication and revert control function between PC or data sampler and equipments, controlling analyzer by upper computer, remote-upgrading data sampler or analyzer by internet.
l Automatic and Manual Measurement: measuring by auto-online, manual-offline and auto-offline.
l Display: LCD operational interface (5.7 Inch), displaying running status.
l Storage: stored detection data above 2000 groups, supporting RS-232, RS-485 communication terminal, 4~20mA output.
l Communication Protocol: formulated based on requirements.
l Data Output: simulation(4~20, 0~20mA, 0~5v) (adapting),digit (RS232 orRS485).
