WXZJ-G Series Total Chromium Online Analyzer

The WXZJ-G Series Total Chromium Online Analyzer is used for online automatic continuous analysis and detection of total chromium in industrial wastewater, surface water, drinking water, seawater, and industrial process control.

Features of the WXZJ-G Series Total Chromium Online Analyzer:

★ Unique design, making this product have lower failure rate, lower maintenance, lower reagent consumption, and higher cost performance compared to similar products.

★ Optical components: Adopts a dual-beam system rarely used in domestic online monitoring instruments, unaffected by various environmental factors during detection. Automatically corrects system errors, improving measurement accuracy, stability, and repeatability.

★ Selection valve components: Uses original imported components from the United States, Japan, or Germany. Mainstream international fluid components with smaller dead volume and simpler operation.

★ Metering components: Achieves precise reagent metering through a visual photoelectric system, overcoming quantitative errors caused by peristaltic pump tube wear; simultaneously enables precise micro-reagent dosing, with each dose only 1-5 ml, greatly reducing reagent usage.

★ Sampling components: Negative pressure suction by peristaltic pump, with an air buffer always present between the reagent and the pump tube, avoiding pump tube corrosion.

★ Sealed digestion components: High-temperature and high-pressure digestion system accelerates the reaction process, overcoming corrosion from volatile corrosive gases in open systems.

★ Reagent tubes: Uses imported modified transparent polytetrafluoroethylene (PTFE) soft tubes with an inner diameter greater than 1.5 mm, reducing the likelihood of sample particle clogging.

★ Signal processing: The instrument uses original imported high-precision analog-to-digital conversion chips, greatly enhancing the expandability of the core board, adapting to various usage environments, and making the instrument operation simpler and more user-friendly.

★ Temperature control: Utilizes imported temperature measurement components to form a precise temperature control system, and adopts temperature compensation technology to overcome temperature drift effects, ensuring that sample reaction conditions better meet requirements.

★ Software advantages:

1. The entire software system framework and external facilities of the instrument make human-machine interaction simpler and functional applications more comprehensive;

2. For different water qualities in specific sites, contamination during the measurement process can be set in real-time, significantly reducing instrument failure rates caused by this issue and making measurement data more accurate;

3. The instrument has an automatic calibration mode. After automatic calibration, the instrument returns to automatic mode and operates according to user-set parameters, eliminating the need for full staff monitoring, greatly reducing maintenance time and improving maintenance efficiency;

4. The instrument measures water samples in two modes: online mode (i.e., automatic mode) and offline mode (i.e., manual mode). In offline mode, calibration tubes are used for measurement without removing the sample tube from the sampling port or cup, making maintenance more convenient;

5. The instrument can store 200,000 data records, and data can be exported with one click;

6. Data from online mode (i.e., automatic mode) and offline mode (i.e., manual mode) are stored independently. Offline mode data is not uploaded to the data acquisition instrument, avoiding impact on uploaded data during instrument maintenance.
