1.Total Chromium Analyzer Principle
Total Chromium Analyzer typically uses spectrocolorimetric methods to measure chromium content, based on the ability of atoms of chromium to absorb specific wavelengths of light.This product uses diphenylcarbazide spectrocolorimetry to determine. After the water sample is mixed with a strong oxidant, trivalent chromium is oxidized to hexavalent chromium. In an acidic environment and in the presence of an indicator, the hexavalent chromium reacts with the indicator to generate a colored complex. The analyzer detects the color change and converts the change into a total chromium value for output. The amount of the generated colored complex is equivalent to the total chromium amount.
2. Features of Total Chromium Analyzer
The new photoelectric quantitative technology is not affected by interference such as large chromaticity, large amounts of suspended matter, and large amounts of bubbles. It has high reliability and accuracy and strong anti-interference ability.
High detection accuracy, low measurement limit and small long-term drift of the instrument.
It has one-button self-test function and self-diagnosis function.
Adopt single-channel highly integrated valve group, maintenance and cleaning are simple and quick.
All-weather networking function, monitor the instrument operation status anytime and anywhere.
It has alarm function, quality control function and reverse control function.
It has automatic cleaning and automatic calibration functions.
It has functions of hourly measurement, interval measurement and external control measurement.
It will work automatically after power failure.
Automatic prompt and automatic reset function for fault and reagent (sample) shortage.
With fault recording function.
Can save historical data for more than 3 years.
Meet the requirement of separate discharge of cleaning liquid and waste liquid

Micrometeorology refers to meteorological changes in very short time and small scale space, usually measuring meteorological parameters within a few metres to a few tens of metres. The main objective of micrometeorological research is to reveal the patterns of variability of meteorological elements...
The Soil Moisture Monitoring Station is an automated device to measure soil moisture and temperature. It consists of a sensor, a data collector, a communication module and a power supply system that automatically collects data and sends it to a remote monitoring centre. This equipment is useful in a...
Agricultural development will encounter some bad weather, such as typhoon, rainstorm, drought, hail, frost, etc., which will bring losses to agriculture. Setting up a meteorological and environmental monitoring system in farmland will help to improve the level of agro-meteorological environmental monitoring in the region, increase the yield of crops, and increase the ability to prevent disasters. With the development of smart agriculture, the model of weather station + Internet continues to develop, and the agricultural environment monitoring system will bring more development opportunities....
In ancient times, without modern technology, it was very difficult for people to predict weather changes. But our ancestors demonstrated their wisdom by observing the sky and animal behaviour to predict the weather. Nowadays, with the advancement of technology, we have advanced weather detection ins...
