technical advantage

Adopting computer reverse control technology, fully computerized digital operation, no manual adjustment, high voltage and threshold are both adjusted by numerical control (see instrument photo, instrument panel without any manual adjustment knob). Greatly improve the stability and accuracy of the instrument.

Introducing CPLD technology into low background alpha beta measuring instrument products improves product integration. Adopting multi-layer circuit board technology, high integration and reliability.

Multi channel independent operation, independent timing measurement, can send samples at any time, greatly improving the efficiency of equipment use. At present, all similar products from other manufacturers in China are in synchronous sample delivery mode, which means that although it is a four channel product that can measure four samples simultaneously, these four samples must be injected simultaneously, and the measurement mode settings (such as measurement cycle and measurement duration) during measurement must also be the same. Even if the user only has one sample and uses one channel, the other channels must still simulate one sample to make all four channels work simultaneously. And the data and reports after the measurement are also from four channels. In other words, if you only use the same channel to measure one sample, but the output report must be from four channels. In this case, there is an excess of useless data on the report. This working mode renders multi-channel meaningless. And each channel of our AL-340 multi-channel low background alpha/beta measuring instrument is independent, with independent sample delivery, independent measurement, independent data and report output. In other words, when the user only measures one sample, they can choose which channel to use and set the measurement mode of that channel (such as measurement cycle and measurement duration). And during this period, if the user has multiple samples, they can choose the remaining unused channels to start a new measurement work, and the measurement mode of each channel can be different.

Designed using the standard WINDOWS multi document program pattern, it has good compatibility with the operating system and runs stably and reliably. It can simultaneously measure, analyze, print preview, and print multiple sets of data. At present, the analysis programs for similar products in China are single document programs, and no other operations can be performed during the measurement process. The multi-threaded mode runs efficiently. Can print test reports and support print preview. It can be equipped with any type of computer, and the data collection and processing of the system, as well as the control of the measurement process, are all completed by the computer.

Adopting a universal USB driver free connection method, the computer has no restrictions (currently, serial port mode is commonly used in China).

By using a flat end detector, the efficiency of the 241Am standard source is increased by nearly 5 times compared to ordinary detectors, which can greatly improve the measurement time and detection limit of a single sample.

Adopting extremely low static current DC high voltage linear stabilization technology, this technology enables the miniaturization of the product control part, improves integration and reliability.

Using a 19 inch standard chassis with protective screen doors, it has a beautiful appearance. The controller adopts a 320 * 240TFT color LCD display output.
