KD221 Portable pH/ORP/°C/°F Meter

KD221 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 accuratemeasurements over the entire range.

Calibration due reminder prompts you to calibrate the meter regularly.

During ORP mode, Single point offset calibration allows user adjustsdisplayed value to a known standard.

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

Automatic endpoint function freezes the stable measured values foreasy reading and recording data.

Manual temperature calibration provides accurate temperature value.

Help message as a operational guide to helps you understand howto 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.
