The Chauvin Arnoux CA 10001 is a compact, waterproof pH and temperature tester designed for fast and spot measurements in various application areas. The device features a convenient pocket-sized format and a 12 cm long pH electrode with integrated temperature sensor, enabling precise measurements even in narrow containers such as sample vials or test tubes. The IP65 protection rating ensures high robustness, making the tester suitable for mobile use in laboratories or on-site.

Applications

The CA 10001 is suitable for a wide range of applications where water quality plays a critical role. These include hydroculture, monitoring of swimming pools and spa baths, water treatment and drinking water analysis, the beverage industry, agriculture, as well as cosmetic and chemical laboratories. The device functions are designed for use in both industrial and scientific contexts.

Functions and Equipment in Detail

The device simultaneously displays the temperature-compensated pH value (ATC) and temperature in °C or °F on a large, clearly readable display. Automatic temperature compensation (ATC) ensures that the pH value is correctly displayed regardless of measurement temperature, covering a temperature range of 0 °C to 60 °C (32 to 140 °F). Calibration is performed automatically in 1, 2, or 3 points, with stored buffer solutions being recognized. This reduces calibration effort and increases measurement reliability.

Technology Explained Simply

The pH value resolution is 0.01 pH, enabling very fine measurement accuracy. Temperature resolution is 0.1 °C or 0.1 °F. Measurement deviation is ± 0.1 pH for pH value and ± 1 °C or ± 2 °F for temperature. The electrode is non-replaceable and features a non-rechargeable gel reference system integrated into a break-resistant plastic tube. Power supply is via two 3-V CR2032 batteries, enabling an operating time of more than 100 hours. The device automatically shuts off after 20 minutes of inactivity to save energy.

Compatibility and Accessories

Various accessories are available to support measurements, including buffer solutions with pH values 4.01, 7.00, and 10.01 (DIN-NIST) for calibration. Additionally, a set of three plastic beakers and a transport case are available, facilitating safe transport and storage of the device.

Mounting and Installation

The device is designed as a handheld unit and requires no mounting. Operation is via buttons, with calibration performed by pressing the CAL button and measurement initiated by a simple button press. The display is directly readable, and the HOLD button allows freezing the measurement value.

Operational Advantages

The CA 10001 offers high measurement accuracy with minimal operating effort. Automatic calibration and simultaneous display of pH value and temperature increase efficiency. The waterproof design and compact format make the device a reliable companion for mobile and stationary measurement tasks. The warranty period is one year.

Scope of Delivery

The device is delivered with two 3-V CR2032 batteries, a storage container for the electrode, a multilingual operating manual, and a calibration certificate. The electrode is permanently integrated and not replaceable.
