SX825 portable pH/DO meter แบบภาคสนาม

SX825 portable pH/DO meter

The most cost effective portable pH+Dissolved Oxygen double-parameter meter, suited for industrial and

mining factories, power plant, aquaculture and environmental protection field, especially suited in field and on-site.

 

INTRODUCTION

Double-parameter meter, equipped with pH electrode and conductivity electrode, automatic identification of electrode by meter.

The meter is able to recognize up to 12 types of pH standard buffer solutions. There are three options of standard buffer solutions: USA series, NIST series and Chinese series (CH), there is also customer-defined solution calibration.

The meter provides two special modes for pure water and pure water mixed with ammonia. These special modes offer temperature compensation for pH value, especially suitable for the electricity and petrochemical industries.

DO electrode offers a built-in temperature and salinity sensor with automatic temperature compensation and automatic salinity compensation as well as manual barometric pressure compensation. The measurement is more accurate

Polarographic DO electrode with special DO calibration cover, electrode polarization only requires 3-5 min, three combined membranes convenient to renew.

Equipped with calibration solution and portable case and suited in field and on site.

Meter meets IP57 rating.
