  • Company Profile

Bante221 is a high performance portable pH/ORP meter designed

for outdoor applications. The meter contains a built-in setup menu

that provides many advanced and useful options to improves

accuracy of measurements and simplify operations.

 

 

 

Features:

During the pH mode, Up to 5 points push-button calibration with auto-

    buffer recognition.

Selectable pH buffer standards and temperature units.

Automatically calculates and displays electrode slope after calibration.

Automatic Temperature Compensation (ATC) ensures highly accurate

    measurements over the entire range.

Calibration due reminder prompts you to calibrate  the meter regularly.

During ORP mode, Single point  offset calibration allows user  adjusts

    displayed value to a known standard.

Absolute or Relative millivolt (R.mV) measurement provides accurate

    ORP readings.

Automatic endpoint function freezes the stable measured values for

    easy reading and recording data.

Manual temperature calibration provides accurate temperature value.

Help message as a operational guide to helps you understand how

    to use meter.

 

       

 

Setup menu lets user customizes buffer standards, calibration points,

    stability conditions, resolution, temperature units, date and time to

    meet measurement requirements.

Reset function can resumes all settings to factory default values.

Expanded memory stores and recalls up to 500 readings.

Built-in real-time clock stamps stored data to meets GLP standards.

Stored data can be transferred into computer via USB communication

    interface.
