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 ideal for environments where full-spectrum water analysis is needed, such as in water treatment facilities, quality control labs, and environmental monitoring stations. Its ability to measure pH, conductivity, TDS, salinity, and resistivity from a single sample increases efficiency and reduces equipment clutter. The meter is especially valuable when dealing with diverse water sources—from freshwater to seawater. This comprehensive capability supports accurate and streamlined testing protocols.
The Benchtop Multi-parameter Water Quality Meter offers up to five-point calibration for most parameters, with automatic recognition of standard solutions to reduce user error. Calibration for pH can be performed using USA, NIST, or DIN buffer systems, providing flexibility based on lab preferences. It also features a calibration due reminder, prompting users to maintain the device regularly for optimal performance. These features help ensure reliability across all measurement modes with minimal manual intervention.
Our Benchtop Multi-parameter Water Quality Meter includes a clear LCD screen, auto-hold functionality, and help messages to guide users through setup and measurement. Stability indicators let users know when readings are consistent and ready to record. Its intuitive interface allows quick switching between parameters, which is particularly useful in fast-paced environments. These user-friendly features minimize training time and help reduce operational errors.
Labtron's Benchtop Multi-parameter Water Quality Meter measures temperatures up to 105°C and features both manual and automatic temperature compensation. This ensures accurate readings even in samples with fluctuating or extreme temperatures, such as industrial effluents or heated process water. It also allows users to select between °C and °F, depending on their regional standards or project requirements. Such flexibility enhances the reliability of measurements under diverse environmental conditions.
Our Benchtop Multi-parameter Water Quality Meter includes a reset function to quickly restore factory settings if user configurations become problematic. An automatic electrode slope display alerts users when the pH sensor may need replacement, helping prevent compromised data. Manual temperature calibration is also available to correct any deviations due to sensor aging. These built-in maintenance aids promote long-term stability and reduce downtime.
