HK-338 Conductivity Meter Brief introduction
SCM control system , a high degree of intelligence , accurate measurement , easy to operate . Used for
continuousmonitoring of the strength of the aqueous solution conductive capacity , and thus indirectly to
determine how much of the content of ions in solution , the water quality , widely used in electric power ,
petroleum , chemical , paper and other industries . Features
1. Advanced embedded LAN technology
2. 192 * 64 dot matrix LCD, Chinese and English display simultaneously
3. Unique four wire measurement techniques, can ignore cable length's influence on the measurement
4. According to the graph can be intuitive conductivity change trend
5. All operating and programming are done by 8 touch membrane keyboards
6. Programming function of the instrument have a 4 digit security code protection, cannot be
easily changed
