Deskripsi

Portable pH/ORP Meter

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

Auto-Power Off effectively conserves battery life

Setup menu allows setting the pH buffer set, number of calibration points, resolution, stability criteria, temperature unit, date and time, etc.

Reset function automatically resumes all settings back to the factory defaults

Expanded memory stores or recalls up to 500 data sets
