07 MDet-5000 TNi Colorimetric Heavy Metal Water Quality Online Analyzer

Product Overview

The MDet-5000 TNi colorimetric method heavy metal water quality online analyzer is based on the principle of the national standard method for measuring total nickel in water quality (GB 11910-89). Under high-temperature sealed conditions, persulfate is used to decompose nickel containing compounds in water samples into nickel ions. In alkaline media, nickel ions react with butanedione oxime to form compounds with strong absorption in the characteristic wavelength range. Calculate the TNi content in the water sample by measuring the compound.

The MDet-5000 TNi colorimetric heavy metal water quality online analyzer is widely used for total nickel monitoring in industrial production processes (such as electroplating, batteries, etc.).

Product Features

High reliability, low maintenance required

The key components are all imported, with high reliability and long service life, suitable for long-term online monitoring;

The measurement module adopts photoelectric measurement method, and the detector does not directly contact the liquid, so there will be no situation where the measurement cannot be stopped;

The flow path is specially designed to be less prone to blockage.

Mature technological means to ensure high accuracy

Optoelectronic metrology uses special metrology algorithms to ensure accurate injection and small injection errors;

Unique bubble mixing technology ensures thorough mixing of samples and reagents during continuous injection;

The automatic chromaticity and turbidity compensation algorithm fully considers the actual water sample situation on site, and the monitoring results are true and reliable;

The patented annular multi-channel dilution injection technology enables the expansion of a large range ratio;

Mature measurement methods derived from national standards have been extensively applied to ensure the reliability of measurements.

Multiple practical functions, providing humanized operation

Automatic leakage alarm function, when reagent leakage occurs, the instrument self checks and alarms, prompting the user to perform maintenance;

Automatic handling of abnormal states. When an abnormal power outage occurs during operation, the instrument will self diagnose the abnormal state and clean the flow path to restore it to the waiting state for sample preparation when power is restored next time;

The instrument is easy to operate, with a full touch screen control panel and friendly software interface that provide rich information prompts. The software operation is simple and easy to understand;

Equipped with multi-level management permissions, password settings, and screen digital locks to prevent accidental operations by others.
