Date and time

The portable conductivity meter CA 10141 from Chauvin Arnoux is a waterproof device for precise measurement of conductivity, TDS value (Total Dissolved Solids), specific resistance, salt content, and temperature. It is designed for use in the field, in laboratories, and for process monitoring, and is particularly suitable for controlling water quality in drinking water systems, wastewater treatment plants, the food industry, and for measurements in natural water bodies. The protection rating IP67 ensures high robustness and complete sealing against dust and water, even during immersion, enabling use in outdoor or humid environments.

Applications

The device is used in various industries, including drinking water production, wastewater treatment, the chemical industry, food production, boiler feedwater monitoring, and environmental protection. It is used for limit value monitoring, routine measurements, and evaluation of water samples. The nonlinear temperature compensation according to ISO-DIN standard 7888 makes it especially suitable for measurements in natural water bodies, where temperature can vary significantly.

Functions and Equipment in Detail

The CA 10141 features an extra-large, backlit LCD display, enabling clear and comfortable reading of measurement values even in poor lighting conditions. The signal stability indicator ensures reproducible and reliable measurement results. The device stores more than 100,000 measurement values with date and time, which can be stored manually or automatically. The included PC software enables device configuration, data transfer, and evaluation of stored measurement values.

Technology Explained Simply

Measurements are performed using the included 4-pole conductivity probe XCP4ST1, which has an integrated temperature sensor (Pt 1000). This enables temperature-compensated measurements, with the user able to choose between automatic (ATC) and manual (MTC) compensation. Compensation can be linear or nonlinear, with nonlinear compensation according to ISO-DIN standard 7888 set as default. The measurement range extends from 0.050 µS/cm to 500.0 mS/cm, with resolution varying between 0.001 and 0.1 depending on the range. The intrinsic uncertainty is ± 0.5% ± R. The reference temperature can be set to 20 °C or 25 °C.

Compatibility and Accessories

The device is equipped with a DIN 8-pin connector, connected to the probe via a 1 m cable. Optional adapters for BNC, S7, and jack connectors are available to connect other probes. Suitable standard calibration solutions, such as conductivity standard solutions with 147 µS/cm, 1408 µS/cm, or 12.85 mS/cm, as well as a calibration kit for pH meters and conductivity meters, are available as accessories. Calibration is performed using a 1-point method with 6 predefined conductivity standards, which can be adjusted by the user.

Installation and Mounting

Installation is done by simply connecting the probe to the device. The device is powered by 4 alkaline AA batteries (1.5 V), which are inserted into the device. Battery life is approximately 300 hours in continuous operation. Automatic shutdown can be set to 3, 10, or 15 minutes of inactivity. Batteries can be replaced without removing the protective cover. The device is delivered in a transport case, which also includes sample containers.

Operational Advantages

The combination of waterproof design, large display, integrated temperature compensation, and large memory capacity makes the CA 10141 a reliable tool for mobile and stationary applications. The PC software enables easy data analysis and documentation. The device warranty is 2 years. The device is designed for use in a temperature range of -10 to +55 °C, with storage conditions (without batteries) between -20 and +70 °C. Dimensions are 211 x 127 x 54 mm, and weight (without sensor) is 600 g.

Scope of Delivery

The device is delivered with the conductivity probe XCP4ST1, a USB cable, PC software for data evaluation, a transport case, and the user manual.
