Portable pH and conductivity meters<\/strong> with external probes are suitable for bench checks, collected samples and all situations where it is useful to position the electrode directly in the solution container. The range includes a pH meter, a conductivity meter and a combined model that brings both parameters together in the same instrument.<\/p>\n

These instruments make it possible to check important characteristics of aqueous solutions during laboratory checks, process activities, water treatment, wastewater management, environmental monitoring, swimming pool and aquarium checks, electroplating, food and beverage applications. The separate probe makes measurements more convenient in beakers, glasses, containers, sample trays and vessels collected directly from the system.<\/p>\n

The pH meter<\/strong> detects the acidity or alkalinity of the solution. The conductivity meter<\/strong>, also known as a portable conductivity meter, measures the ability of the liquid to conduct electrical current, a parameter related to the presence of salts and other dissolved ions. The models dedicated to conductivity also provide readings of TDS, salinity, resistivity and temperature.<\/p>\n

Automatic temperature compensation supports measurement when the sample temperature changes. All instruments also make it possible to store readings, recall them later and work with an external probe, which is useful for repeated bench checks or samples collected at different points.<\/p>\n

pH and conductivity meters: which one to choose<\/h2>\n

The choice depends on the parameters to be checked and on the type of verification required.<\/p>\n

The model dedicated to pH is suitable when the check concerns only acidity, alkalinity, mV potential and solution temperature. It can be selected as a professional pH meter with external probe<\/strong> for checks on water, process baths, chemical solutions and collected samples.<\/p>\n

The conductivity meter is suitable when the presence of dissolved substances needs to be checked through conductivity, TDS, salinity, resistivity and temperature. It is a useful choice for checks on deionised water, process water, saline solutions, wastewater, washing liquids and samples where conductivity is the main parameter.<\/p>\n

The combined pH and conductivity model brings both measurements together in the same instrument. This configuration is useful when both pH and conductivity need to be checked on the same sample, avoiding the need to work with two separate instruments.<\/p>\n

pH meter with external probe<\/h2>\n

The pH meter with external probe is designed for checks on liquid samples carried out at the bench or directly close to the system. The probe can be inserted into the sample container while the display remains easy to read, making operation more convenient than with a pen-type<\/a> format.<\/p>\n

In addition to pH, the instrument measures mV potential and displays the solution temperature. The option to select the reading resolution makes it possible to adapt the check to the required verification, from routine assessments to controls requiring greater accuracy.<\/p>\n

For very quick checks directly at the control point, a pen pH meter can be useful. When the sample is collected and analysed at the bench, the external probe provides more convenient and organised measurement handling.<\/p>\n

Conductivity meter and portable conductivity meter<\/h2>\n

The conductivity meter<\/strong> is suitable for assessing aqueous solutions in which the presence of salts or dissolved ionic substances affects the characteristics of the liquid. In addition to conductivity, the instrument displays TDS, salinity, resistivity and temperature, providing more useful data from the same sample.<\/p>\n

The portable conductivity meter can be used for checks on deionised water, washing water, technical solutions, wastewater, water-treatment systems and samples used in industrial processes. The external probe facilitates bench testing and makes it possible to work more conveniently with containers of different sizes.<\/p>\n

Salinity measurement is useful when saline solutions need to be monitored, while resistivity is useful for checks on low-conductivity water. TDS reading provides an indication of the total content of dissolved substances in the liquid.<\/p>\n

Combined pH and conductivity meter<\/h2>\n

The combined pH and conductivity meter makes it possible to check pH, mV, conductivity, TDS, salinity, resistivity and temperature with a single instrument. It is suitable when sample analysis requires comparison between the acidity or alkalinity of the solution and the presence of salts or dissolved substances.<\/p>\n

This configuration is particularly useful for process checks, water treatment, electroplating baths, washing solutions, wastewater, environmental applications and checks on liquids used during technical operations.<\/p>\n

The availability of two separate probes makes it possible to use the most suitable sensor for the parameter to be checked, keeping pH measurement separate from conductivity measurement.<\/p>\n

Salt spray chamber solution monitoring<\/h2>\n

The combined pH and conductivity meter can also be used for internal checks on solutions used in salt spray chambers<\/a>.<\/p>\n

In the NSS test according to UNI EN ISO 9227, conductivity makes it possible to check the deionised water used to prepare the saline solution. pH, on the other hand, makes it possible to check the sprayed solution collected in the dedicated collectors inside the chamber, an important parameter for assessing whether test conditions remain consistent during exposure.<\/p>\n

Conductivity measurement can also be used as an internal comparative check of the prepared saline solution and the sprayed solution collected in the collectors. However, it does not replace the verification of sodium chloride concentration required by the applicable procedure.<\/p>\n

The check must refer to the sprayed solution collected in the chamber collection devices, not to liquid dripping from the test panels or internal walls. The availability of pH and conductivity in the same instrument therefore makes it more practical to monitor solution checks before the test and during chamber operation.<\/p>\n

Electrodes and long-term use<\/h2>\n

The availability of external probes makes these meters suitable for continuous checks on collected samples. pH and conductivity electrodes in plastic or glass are available, making it possible to choose a configuration suited to the type of liquid and the intended use.<\/p>\n

Replaceable electrodes help keep the instrument operational over time and adapt it to control requirements that may vary between laboratory, production, maintenance and environmental checks.<\/p>\n

Calibration report<\/a> available on request<\/strong>, to provide the pH and conductivity meters with metrological documentation useful for internal checks and for monitoring their status over time.<\/p>\n
