The temp. coefficient is the % change of conductivity with temperature in %/°C. 2.2 Characteristics The INE-DDBJ-350 portable Conductivity Meter is an intelligent analysis instrument; it is suitable for measuring conductivity, temperature, TDS of water solution and salinity. It can also be used to measure purity of pure water, salinity of seawater as treating desalination of seawater (take NaCl as standard). - Page 9 INE-DDBJ-350 Conductivity Meter Measuring conductivity, TDS, salinity and temperature. Auto temperature compensation, auto-calibration, auto-range, Power-off protection. When the meter is manually or automatically shut off, the stored measuring data, calibration data, and setting parameters will not be lost.
- Page 10 INE-DDBJ-350 Conductivity Meter automatically: (0.000~9.99) mg/L (10.00~99.9) mg/L (100.00~999) mg/L (1.00~10.00) g/L (10.00~19.99) g/L (cell constant should be 5 or 10) Note: When measuring high TDS, the conductive probe of large constant is usually used, when TDS≥10.00g/L, the probe of 5 or 10 constant must be used.
