portable pH&conductivity meter

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.

◆ The meter is able to switch among conductivity, TDS, salinity and resistivity measurement mode. For TDS measurement, the coefficient is adjustable.

◆ The meter is able to recognize up to 8 types of conductivity standard solutions. There are two options of standard buffer solutions: USA series and Chinese series (CH), there is also customer-defined solution calibration.

◆ The meter has an automatic range feature with automatic non-linear temperature compensation for pure water and high purity water with conductivity values lower than 10uS/cm greatly improving accuracy and suitable for the electricity, microelectronics and pharmaceutical industries.

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

◆ Meter meets IP57 rating.
