The pH/T-Tester CA 10002 from Chauvin Arnoux is a compact probe for precise determination of pH value and temperature in foodstuffs as well as in agricultural applications. The device features a penetrating glass tip, specifically developed for semi-solid, doughy, or protein-containing substances, enabling measurements in samples with small diameters. The integrated temperature measurement occurs simultaneously with the pH display, with the ATC mode (Automatic Temperature Compensation) ensuring automatic temperature compensation. The measured values are displayed on a large screen in °C or °F, with a resolution of 0.01 pH for pH values and 0.5 °C or 0.5 °F for temperature. Accuracy is ± 0.1 pH and ± 1 °C or ± 2 °F.

Applications

The CA 10002 is specifically designed for the food industry, where it is used for fermentation testing in dairy products, checking the ripeness of cheese, and assessing milk quality. Additionally, the device is suitable for determining soil pH in agriculture. Due to its fast response time and high accuracy, it is also suitable for preliminary testing in research and development.

Functions and Equipment in Detail

The device offers automatic calibration with a single button press (CAL button), automatically recognizing the buffer solution. Calibration can be performed at one, two, or three points using stored buffer solutions. The electrode is non-replaceable and features a non-refillable gel reference system. The measuring tip is 12 cm long and equipped with a fiber diaphragm, enhancing measurement accuracy in viscous or semi-solid samples. The display includes a HOLD button to lock the current measurement value.

Technology Explained Simply

Measurement is performed using a special pH electrode with a penetrating glass tip, which is inserted into the sample. The integrated temperature probe simultaneously measures the sample temperature. Automatic temperature compensation (ATC) ensures that the displayed pH value is referenced to the measured temperature, which is essential for precise results in different environments. A resolution of 0.01 pH allows detailed representation of pH values, while a temperature resolution of 0.5 °C ensures accurate temperature measurement. The deviation of ± 0.1 pH and ± 1 °C ensures reliable measurement accuracy.

Compatibility and Accessories

Various accessories are available for the pH/T-Tester CA 10002, including buffer solutions for pH 4.01, pH 7.00, and pH 10.01 (DIN-NIST), each containing 125 ml. A set of three plastic beakers is also available to perform calibration and measurement in a clean environment. A transport case with dimensions 120 x 245 x 60 mm provides protection and convenient transport for the device.

Mounting and Installation

The device is ready for immediate use once the batteries are inserted. It requires no additional mounting or installation. Operation is via an intuitive button interface, allowing calibration and measurement to be performed easily and quickly. Automatic shutdown after 20 minutes of inactivity ensures efficient power usage.

Operational Advantages

The CA 10002 is characterized by its compactness and portability, with dimensions of 228 x 36 x 20 mm and a weight of 65 g. The plastic housing reduces the risk of breakage. Water resistance rated IP65 protects the device from dust and water, making it suitable for outdoor use. Power supply is via two CR2032 batteries (3V), providing a lifespan of over 100 hours. Operating temperature ranges from 0 to 80 °C, with a maximum relative humidity of 80 %. The warranty period is one year.

Scope of Delivery

The device is delivered with two CR2032 3V batteries, an electrode storage container, a multilingual operating manual, and a calibration certificate.
