 Benchtop Multi-parameter Water Quality Meter LMPWM-A30 Catalog
Labtron offers a wide range of Benchtop Multi-Parameter Water Quality Meters for accurate analysis of various parameters. Their compact and lightweight design allows measurement of pH, conductivity, dissolved oxygen, salinity, and more. These meters support data storage and efficient data export for further analysis. The built-in microprocessor enables various functions such as auto-calibration, self-diagnosis, and clock display. Our Benchtop Multi-Parameter Water Quality Meters are ideal for water analysis, research laboratories, and industrial quality control.








Labtron Benchtop Multi-parameter Water Quality Meter is highly versatile, making it ideal for research labs, water treatment plants, quality control in manufacturing, and environmental monitoring. It is particularly beneficial where multi-parameter testing of pH, mV conductivity, and TDS is needed from a single device. This reduces equipment costs and streamlines workflow. Its wide measurement range and customizable calibration settings ensure accuracy across a variety of water types and conditions.
Our Benchtop Multi-parameter Water Quality Meter is designed with intuitive features like auto hold, help messages, and a stability indicator, which make operation simple even for beginners. The LCD screen clearly displays data and prompts, and push-button calibration automates buffer recognition. Users can choose between different buffer standards (USA, NIST, DIN), aiding flexibility and reducing guesswork. These usability features make it equally suited for academic labs and high-throughput industrial settings.
The Benchtop Multi-parameter Water Quality Meter includes a calibration due alarm that reminds users when it is time to recalibrate, helping prevent inaccurate results from drift or wear. Automatic temperature compensation and customizable compensation modes help maintain consistency across varying water temperatures. The automatic electrode slope display also signals when sensor replacement may be necessary. These safeguards are crucial for ensuring measurement reliability over time.
Yes, Labtron's Benchtop Multi-parameter Water Quality Meter stores up to 500 sets of data and includes a USB interface for easy data transfer to a computer. This is essential for labs or facilities that need traceable, documented testing for compliance, audits, or quality reporting. The auto/manual endpoint detection ensures only stable readings are recorded. Together, these features support efficient digital recordkeeping and analysis.
The Benchtop Multi-parameter Water Quality Meter allows selection of cell constants of K = 0.1, 1, 10 and normalization temperatures of 20°C or 25°C, offering precise conductivity and TDS readings across different water qualities. It also supports linear and pure water compensation modes, improving accuracy based on the sample’s ionic strength. This makes it suitable for everything from ultra-pure water analysis to seawater salinity testing. The ability to define TDS conversion factors enhances application-specific accuracy.
