Laboratory PH/Conductivity Meter for Water Testing Lab

Laboratory PH/Conductivity Meter for Water Testing Lab

It has a very wide range of applications and can be used in most fields related to water quality analysis. With its advanced digital processing technology, it provides fast, accurate, stable, and higher precision measurement results. The laboratory pH/conductivity meter is a dual parameter electrochemical measuring instrument for measuring pH/conductivity values in conventional aqueous solutions with moderate ion strength.

Features

Automatically identify pH standard buffer solutions, with three series of standard buffer solutions to choose from: European and American series, NIST series, and Chinese series.

Standard 201T-M triple composite pH electrode, suitable for fast and accurate measurement of conventional aqueous solutions. pH electrode+reference electrode+temperature electrode, can simultaneously measure pH and temperature values, achieving automatic temperature compensation; The pH sensitive membrane using lithium glass formula has low impedance and stable potential; Two liquid interfaces, sand core and fiber thread, effectively improve the problem of liquid interface blockage; Lead free glass support rod, in compliance with food safety regulations;

Compliant with international GLP requirements, it has intelligent functions such as automatic calibration, automatic temperature compensation, data storage, RS232 output, clock display, function settings, and self diagnostic information.

By using digital filtering and frequency slip technology, the response speed of the instrument and the accuracy of measurement data are intelligently improved, and a smiling face icon is displayed when the measurement value is stable.

By adopting advanced automatic frequency conversion and automatic voltage regulation technology, the measurement range of the constant K=1 conductivity electrode is expanded by 10 times. With just one point calibration, it can meet the measurement accuracy requirements within the range of 100 mS/cm.

Electrode bulb cover: protects the glass bulb from damage and can be disassembled for electrode cleaning.

Standard 2301T-M rugged platinum black conductive electrode (K=1). The sturdy platinum black coating not only increases the electrode surface area and reduces polarization effects, but also improves the adhesion between platinum black and metal. The coating is sturdy and can be cleaned with a soft bristled brush; Built in 30k Ω thermistor with automatic temperature compensation function. Can accurately measure low conductivity samples, such as pure water, distilled water, and soft surface water; The electrode rod made of POM material has excellent chemical and mechanical properties.

Compliant with IP54 dustproof and splash proof, the instrument socket is sealed with a silicone cap for protection.
