Notice
• For samples below 20μS/cm, it is recommended to use 0.1 constant or 0.01 constant Conductivity detector Electrode measurement
• Use ambient temperature range 0-40 ℃
• Operating Environment relative humidity not more than 85%
• Instrument power supply is dedicated Power Adapter (input: AC100~ 240V output: DC9V)
• The instrument level is 0.5, and attention should be paid to the Measurement accuracy requirements when using it
• The matching 1.0 constant Electrode can cover the full range of measurement, but the appropriate Electrode constant needs to be selected according to the characteristics of the sample
• Support firmware upgrade, can be extended as needed
