อุปกรณ์วัด Conductivity/TDS (Conductivity Bench with graphic display)

HI 4321-02
Conductivity Bench with graphic display

HANNA presents a new family of benchtop instruments which, thanks to its many functions and advanced features are able to meet all the needs of laboratories and research departments. Among the main features include the large color graphic display (240 x 320 pixels) with on-screen help, simultaneous graphing, language selection and configuration customization.
For the analysis of conductivity  HI 4321 allows measurements in four different scales: EC,  resistivity, TDS and salinity . For the analysis of EC is PU2 rely on a wide scale by 0001  S / cm to 1 S / cm, with automatic recognition of the type of probe used. The measures salinity can be viewed as salinity  practice, natural sea water or percentage scale.
Another key feature of this tool  the possibility to perform the three stages of analysis required by the United States Pharmacopeia for the quality  water (USP). HI 4321-01 with USB and RS 232 interface for connection to PC and provides storage functions and GLP (Good Laboratory Practice).
