520/530/531/540 Series

Portable Conductivity/TDS/Salinity/^oC Meter

This Series meters for conductivity and related measurements operate from a CPU for high accuracy measurements and data storage and output.

Automatic Calibration:

The meters is capable of calibrating up to 5 points using standard solution. From Setup Menu, choose Calibration and press key to set known conductivity value, immerse conductivity electrode into calibration solution, press ENTER key and meter is automatically calibrated.

Conductivity Auto-Ranging:

The meters have auto-range functions for measuring conductivity and total dissolved solids (TDS). 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, this series can set the temperature coefficient between 0 and 3.9% in degrees Centigrade for optimum accuracy.

Adjustable Cell Constant:

This series 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.

Adjustable TDS Coefficient:

530/540 meters can manually switch ranges between .01 and 1.00 to ensure optimum measurement accuracy. 0.01 and 1.00 to ensure optimum measurement accuracy.

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.

Functions:
