The Conductivity-Meter LF1010 has been designed for the measurement of conductivity, as a degree of the purity or concentration of a liquid.
In connection with 4-electrode-conductivity cells a high accuracy and insensitivity of contamination can be achieved. A further advantage is a broad range of application with only one cell. Only for measurement in ultra-pure water a special 2-electrode conductivity cell must be used.
The input supports 2- or 4-electrode conductivity cells, with Pt100 or Pt1000 temperature compensation
The device provides non-linear temperature compensation for ultra-pure water and natural water, or linear compensation (adjustable from 0.000..9.999 %/K)
Conductivity values are shown on a red LED display with leading zero suppression. A separate 2-digit red LED parameter display indicates parameters and outputs.
The field case is made from PA6-GF15/15 with a polyester keypad. Electrical connection is made via clamp terminals
The LF1010 can be configured without alarm output or with two relay outputs. Alarm function can be programmed as minimum or maximum function.
Versions are available for 230 V AC, 115 V AC, 24 V AC or 24 V DC supply, depending on the selected ordering configuration
