PH-220 Features:

* 1 to 3 points calibration with automatic recognition for USA and NIST buffers.

* Automatic electrode diagnosis helps user decide whether to replace the pH electrode.

* Automatic temperature compensation ensures accurate readings over the entire range.

* Auto-Read function senses and locks the measurement endpoint.

* Setup menu allows setting the pH buffer set, number of calibration points, temperatureunit, auto-power off, etc.

* Reset function automatically resumes all settings back to the factory defaults.

* Expanded memory stores or recalls up to 100 data sets.

* USB communication interface for data transfer or connecting a power adapter to meter.

PH-221 Features:

PH

* 1 to 5 points calibration with automatic recognition for USA, NIST and DIN buffers.

* Automatic electrode diagnosis shows the pH slope and offset.

* Automatic temperature compensation ensures accurate readings over the entire range.

* Calibration due alarm prompts user to calibrate the meter regularly.

ORP

* 1 point offset calibration allows adjusting the displayed value to a known standard

* Relative and absolute millivolt modes ensure the reliable ORP measurements

General Features

* Auto-Read function senses and locks the measurement endpoint
