Boke540 portable meter is used for measuring the conductivity, TDS, salinity and temperature in liquids.


Boke540 portable meter has auto-range functions for measuring conductivity and total dissolved solids (TDS). Upon immersing conductivity sensor into sample solution, the screen immediately displays the reading in appropriate measurement range for accuracy.

Automatic Calibration:

The meters is capable of calibrating the one point in each of the measuring ranges. From Setup Menu, choose calibration and press the key to set known conductivity values, immerse the conductivity cell into calibration solution, press ENTER key and meter is automatically calibrated. 

Calibration Solution Recognition:

During the calibration, if the calibration solution does not match the meter’s indicated value, an ERROR message is displayed.This function will prevent an inaccurate calibration.

Adjustable Temperature Coefficient: 

Various ions may have different temperature coefficients, The meters can set the temperature coefficient between 0 and 3.9 % in degrees Centigrade for optimum accuracy.

Adjustable Cell Constant:

The meters have 3 cell constants for measuring requirements. Once a cell constant has its calibration set, it is saved and does not require re-calibration when switching sensors.

Adjustable TDS Coefficient: 

Boke 530 and 540 meters can manually adjustable TDS coefficient between 0.01 and 1.00 to ensure optimum measurement accuracy.

Automatic Temperature Compensation: 

The meters provide manual or automatic temperature compensation mode for optimum accuracy under variable temperature conditions.Insert the temperature probe into meter, the temperature value will automatically displays on the screen.

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, the user can easily view and record data.

Power Monitor: 

During using, the power chip will continuously monitors the battery level, When the battery is running out of power, the battery icon will disappear from the screen. 

Message Indicator: 

Boke 5 series meters have message indicator, it can shows many helpful messages like an on-screen manual for easy operation.

Communication Interface and Data Store: 

The meters have 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.

Meter Included:

Conductivity Cell, Temperature Probe, Battery. 

Optional Accessory: Carrying Case.
