Product description (N-LF2000, conductivity measuring instrument 0-20/200/2000μS/cm in wall mounted housing):

N-LF2000, conductivity measuring instrument 0-20/200/2000μS/cm in wall mounted housing

Device for the measurement of the electrical conductivity of aqueous solutions using a two-electrode conductivity cell. Designed for wall mounting installation.
• Operation at 230 V AC or 24 V DC
• 2 potential-free relays – changeover switch for limit values (5 % hysteresis – fixed setting)
• Alphanumeric display with 2 x 16 digits
• Temperature measurement and display between 0.0 °C and 100.0 °C if using a Pt100
• Temperature compensation with 2.2 % / K at 90 °C; can be switched off / disabled
• Temperature sensor is monitored for sensor brake and error message in display
• Switchable operating mode of the relay control
• Analogue output for the measured conductivity value: 0 – 10 V and 4 – 20 mA
