Yes, Labtron’s Benchtop Multi-parameter Water Quality Meter is equipped with a built-in data storage feature that allows it to store up to 1000 sets of test results. This makes it highly convenient for laboratories and field applications where multiple samples are tested over time.In addition, the device supports USB data transfer, enabling users to export the saved data to a USB flash drive. The exported files are compatible with Microsoft Excel, allowing for easy access, analysis, reporting, and long-term record-keeping.
Our Benchtop Multi-parameter Water Quality Meter is primarily used for measuring dissolved oxygen (DO) levels in water. It operates based on an electrochemical principle where oxygen diffuses through a membrane and is reduced at the cathode, generating a current proportional to the oxygen concentration. This type of electrode is ideal for accurate DO measurements in applications such as environmental monitoring, aquaculture, wastewater treatment, and laboratory research. It offers stable readings and is suitable for continuous or routine testing of water quality.
Labtron’s Benchtop Multi-parameter Water Quality Meter is equipped with advanced auto-recognition features that enhance both accuracy and user convenience. It can automatically recognize 25 pH buffer solutions based on international standards, including European, USA, NIST, and China, enabling quick and error-free calibration. Additionally, the meter supports the auto-recognition of 8 conductivity standard solutions, also aligned with European, USA, and Chinese calibration protocols. These features minimize manual input, reduce the chances of calibration errors, and streamline the overall testing process, making the device ideal for high-precision applications in various industries.
Our Benchtop Multi-parameter Water Quality Meter contains a built-in microprocessor chip that powers a suite of smart functions. Including automatic calibration for simplified setup, automatic temperature compensation (ATC) for enhanced accuracy across varying temperatures, and data storage capabilities for convenient record-keeping. Users can also benefit from customizable function settings, a self-diagnosis feature for troubleshooting, an auto power-off function to conserve battery, and undervoltage prompts to indicate low battery status.
Labron’s Benchtop Multi-parameter Water Quality Meter comes equipped with a set of standard accessories to ensure users can begin measurements effectively. Included in the package are the essential sensors: a pH electrode for acidity and alkalinity measurements and a DO electrode for determining dissolved oxygen levels. Additionally, it contains a temperature probe, buffer solutions, DO filling solutions, and a power adapter.
