Instrument Features

1) This product adopts the correction coefficient method detection principle stipulated by the national standard. It strictly follows the national standard formula and uses 20mg/L hexadecane, 20mg/L isooctane, and 100mg/L benzene for calibration. Finally, it is brought into the calibration formula to calculate the instrument correction coefficient for measuring samples (standard curve method can also be used for detection);

2) The instrument is operated using the mainstream Android 7.1 system plus an 8-inch color large screen mode. All instrument operations can be performed through the touch screen, which is convenient and fast, and as easy to use as operating a mobile phone;

3) Built-in wireless network function, external WIFI can be connected to realize the network upload function;

4) Internal 16G storage capacity can store 100W+ data, and USB can be directly exported through a USB flash drive

5) Automatically synchronize network time to avoid the inaccurate local time affecting the accuracy of the output voucher time due to the use of the instrument for too long;

6) Powerful background data support. After the user has tested the sample, he can not only print the results and save them locally through a printer, but also upload the data to the cloud platform through WIFI or 4G to connect to the Internet. library;

7) It not only has basic functions such as detection function setting, curve analysis, historical data, etc., but also can zoom in and out the spectrum, allowing users to infinitely refine the spectrum and observe the curve at low concentration more clearly;

8) Highly automated program application, users can use the Android system to perform individual tests of all instrument functions, automatic wavelength scanning, automatic correction and other functions, making data detection more accurate;

9) One-click program upgrade function, no need for engineers to download on-site, the APP can be upgraded by inserting a USB flash drive;

10) The use of electrically modulated light source not only reduces the heat intensity of the light source to facilitate system heat dissipation, but also simplifies the instrument structure and improves the reliability of the instrument by reducing the mechanical light cutting motion devices;

11) Real-time automatic zeroing, the instrument collects signals when the light source is emitting, and collects signals when the light source is extinguished, realizing real-time automatic adjustment of the zero point, thereby simplifying the operation and improving the long-term stability of the signal;

12) The detachable integrated optical system makes the instrument small in size, short in optical path, and large in energy. The optical path meets the requirements of infrared spectroscopy characteristics, with good stability and high signal-to-noise ratio;
