It is used to measure the pH value and conductivity of conventional aqueous solutions with moderate ionic strength. It has an extremely wide range of applications and can be employed in most fields related to water quality analysis. Relying on its advanced
digital processing technology, it consistently delivers fast, accurate, stable, and more precise measurement results, and has won
wide trust from users.
Features
It complies with GLP requirements in line with international standards, and is equipped with intelligent functions including automatic calibration, automatic temperature compensation, data storage, RS232 output, clock display, function setting, and self-diagnostic information.
It adopts digital filtering and slip technology to intelligently improve the instrument’s response speed and the accuracy of
measurement data, and displays a smiley face icon when the measured value is stable.
It automatically identifies pH standard buffer solutions, with three series of standard buffer solutions available for selection: European and American series, NIST series, and Chinese series.
It comes standard with a 201T-M three-in-one combined pH electrode, suitable for rapid and accurate measurement of conventional aqueous solutions. Integrating a pH electrode, reference electrode, and temperature electrode, it can simultaneously measure pH value and temperature to achieve automatic temperature compensation. It uses a pH-sensitive membrane with a lithium glass formula, featuring low impedance and stable potential. Equipped with two liquid junctions (sand core + fiber filament), it effectively solves the problem of liquid junction blockage. The lead-free glass support complies with food safety standards. The electrode bulb shield protects the glass bulb from damage and can be disassembled for electrode cleaning.
It comes standard with a 2301T-M robust platinum black conductivity electrode (K=1). The robust platinum black coating not only increases the electrode surface area and reduces polarization effects, but also enhances the adhesion between platinum black and metal. The coating is durable and can be cleaned with a soft brush. It has a built-in 30kΩ thermistor with automatic temperature compensation. It can accurately measure low-conductivity samples such as pure water, distilled water, and soft surface water. The electrode rod made of POM (Polyoxymethylene) material offers excellent chemical and mechanical properties.
Adopting advanced automatic frequency conversion and automatic voltage regulation technologies, it extends the measurement range of the K=1 conductivity electrode by 10 times. Only one-point calibration is required to meet the measurement accuracy requirements within the range of 100 mS/cm, which is the unique one-point calibration function of this instrument.
It meets the IP54 dust and splash protection rating, and the instrument interfaces are sealed and protected by silicone caps.
