About This Product
When water measurement is performed, the normal pressure heating and drying method is often the official law. However, the regular pressure heating and drying method takes time and the facilities are large. In addition, the normal pressure heating and drying method in a small amount of water is very difficult.
In the past, such hydraulic water measurements have been used in many problems with curl -fisher droplets (KF methods) using organic solvents, etc., but this method also had various problems. These problems have solved the trace water meter FM-300s. This instrument is a moisture measuring device that complies with the regular pressure heating and drying method.
■ Measurement method
In a heated tube blocked out of the outside air, an infrared light is irradiated with an infrared light and heated and dried, and a vaporizer other than generated water and moisture is carried to the filter with a carrier gas (N2). Therefore, after the water selection operation is performed, only the moisture is extracted in the moisture adsorbent, and the water value is determined from the mass change in the adsorbent.
It is called the Filtered MoistureAdosortion Method, which is the most effective method in measuring a trace moisture by changing the mass due to heating and drying, and is a method that conforms to the official law, which is a public law, is a method of heating and drying.
■ Moisture selection operation
The substances generated by heating and drying are not only moisture, but also organic matters (such as vaporization other than moisture). Operation to remove the generated vaporized goods is called water selection operation. After heating and drying, it is performed once through the activated carbon.
Then, in order to remove only the water, pass through the moisture adsorbent and calculate the final amount of water.
■ Features
･ A voluntary amount 10mg -5g (up to 5g) Sampling method can be easily measured.
･ Since there are 20 measurement conditions registration areas, you can measure more smoothly by registering various samples measurement conditions.
･ By changing the gas flow rate of carrier gas, the measurement time can be reduced.
･ Since an automatic stop mode is provided, the measurement accuracy or condition can be performed according to the purpose.
･ Connect to a printer (option) and print out character data, such as drying status and final measurement value during the measurement, or graph.
･ By using data management software (options), data management and operation can be performed from the computer.
･ Large LCD with backlight allows the display part to be easy to see, and you can check the dry curve even during measurement.
･ The built -in balance calibration can be done by simple operation.
