·         Function

1.Solid calibration sample automatic calibration

Function daily use, whether the accuracy of the instrument is within the error range, on the one hand, can be identified through the analysis of the standard sample of known concentration HK-S1710 can also through the analysis of the solid sample   of fixed chloride content determine instrument counting rate attenuation, to determine whether can continue to use the standard curve.

After use for a long time, if instrument performance attenuation, calibration can be based on the analysis of solid samples to automatic calibration standard curve, one-time all standard curve correction, easy to use, the results are accurate.

2. Sample cup forming device ESP (easy sample prepare)

Simple sample cup and film forming device, convenient for sample preparation, ensure the consistency avoid contamination of the sample film, greatly reduce the cost.

3. Data analysis software

Daily analysis of the data stored in the U disk or SD card, computer version of the software for statistical data on stirage of classification management, can analyze the type of sample data over a period of time average, concentration range, etc.
