Portable conductivity meter Model 520 is used for measuring the electrical conductivity of liquids. Portable conductivity meter includes Models 520, 530, 540.
Automatic Calibration: Model 520 meter is capable of calibrating up to 5 points using the standard solution. From Setup Menu, choose Calibration and press key to set known conductivity value, immerse conductivity electrode into calibration solution, press the ENTER key and meter is automatically calibrated.
Auto-Standard Recognition: During calibration, if the calibration solution or selected value does not match the meter's indicated value, an ERROR message is displayed.
Conductivity Auto-Ranging:The meter has auto-range functions for measuring conductivity. Upon immersing conductivity sensor into sample solution, the screen immediately displays the value in appropriate measurement range for accuracy.
Automatic Temperature Compensation: Using the supplied temperature probe, the temperature value is displayed on the screen. The meters provides manual or automatic temperature compensation mode for optimum accuracy under variable temperature conditions.
Adjustable Temperature Coefficient: Various Ions may have different temperature coefficients, meter can set the temperature coefficient between 0 and 3.9% in degrees Centigrade for optimum accuracy.
Adjustable Cell Constant: The meter has three cell constants for measuring requirements. Once a cell constant has its calibration set, it is saved and does not require re-calibration when switching electrodes.
Hold Function: To keep the latest measurement on the display, after taking a reading press the HOLD key and the measurement remains on the display, You can easily view and record data.
Power Monitor: During using, The CPU continuously monitors and displays the battery level, When the battery is running out of power, The battery icon will disappear from the LCD.
Message Indicator: meter has message indicator, it can shows many helpful messages like an on-screen manual for easy operation.
Communication Interface and Data Store: The meter has real-time date/clock stamps, the memory stores up to 64 data sets. Press the SAVE key to store the current measured values and it automatically generates a serial number with time. All of stored data can then be sent to a computer via the USB port.
