Laboratory Ammonia Nitrogen Analyzer
The SK-100 series laboratory ammonia nitrogen automatic analyzer is based on the principle of the National Environmental Protection Administration-ammonia nitrogen test standard analysis method "Nessler's reagent colorimetry" principle, combined with the latest technology development of flow injection analysis. A generation of automatic ammonia nitrogen analyzer. The instrument can be widely used in environmental protection, health and epidemic prevention, water conservancy, agriculture, chemical industry, tap water, aquaculture, marine survey, sewage treatment, production water quality control and other industries and departments that need to analyze ammonia nitrogen content in water.
Through the method of reference light source, the instrument eliminates the interference of the power supply fluctuation, component aging, working environment changes and other factors on the measurement result, thereby improving the measurement accuracy. In addition, the use of semiconductor light source circuit and large-scale integrated circuit design and computer data acquisition and processing system has achieved the measurement of high precision and high stability of the instrument. The use of a built-in sample distillation pretreatment device (patented technology, patent number: ZL200620119263.5) allows the water sample to be tested directly into the ammonia nitrogen analyzer without any pretreatment. This product also has the functions of automatic distillation pretreatment, automatic cleaning of pipelines, automatic correction of zero point, automatic establishment of working curve, automatic display, automatic storage of measurement data and graphics, and printing.
1. Main features:
· Fast analysis speed: single sample injection + sample pretreatment + colorimetric + measurement + result display = 10min
· High test accuracy: using unique colorimetric device, liquid circuit control system and powerful microprocessor to control the instrument, not only exclude
In addition to various interference factors in the test, the measurement accuracy and precision are greatly improved.
· Built-in pretreatment function: independent research and development, unique sample pretreatment device-patented technology (patent number: ZL200620119263.5),
Enhanced the detection range of the instrument and the accuracy of the tested samples. At the same time, the quality of suspended particles and colored water can also be directly detected.
· Simple operation and high degree of automation: all functions of the instrument can be completed by operating the computer keyboard, which truly realizes the instrument ’s
Fully automated analysis.
· Low failure rate: Because the optical system and light source system of the instrument adopt the latest international technology, the circuit system adopts large-scale integration
The circuit design simplifies the optical system and circuit structure of the instrument and reduces the failure rate of the instrument.
· Low cost of use: each sample is tested, the sample injection volume is only 10ml, the use of Nessler's reagent is about 1ml,
To a great extent, it saves cost for the operator.
· Convenient maintenance: In addition to adding reagents on a regular basis, the pump tubing needs to be replaced for several months or even years according to different usage conditions.
Its daily maintenance is extremely simple.
· Standard equipped with 50-bit three-dimensional automatic sampler, which can realize sequential sample injection and arbitrary sample injection (referring to SK-100A type).
A Sublimation Keychain is a Customised Keychain that is made using the sublimation printing process. Sublimation printing is a process in which ink is transferred onto a substrate (in this case, a keychain) using heat and pressure. The ink is first printed onto a transfer paper and then transferred onto the Custom Keychain using a heat press. This process allows for high-quality, full-color images to be printed onto the Keychain Custom, making it a popular choice for customizing Sublimation Key Chains with logos, photos, and other designs. Sublimation Keychains are durable and long-lasting, making them a great promotional item or gift.
Welcome to find us to customize your own keychain!
