KINGDAK221 high quality/economic Portable pH/ORP Meter

KINGDAK221 Portable pH meter is a high performance meter designed for outdoor applications. The meter contains a built-in system 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 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 parameters.
* 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.
