  • Chemical-Resistant Materials: Durable construction ensures longevity

  • Break-Resistant pH Electrode: Optional ToupH pH electrode available for added durability*

  • Field Replaceable Sensors: Easy maintenance, reduced downtime

  • Comprehensive Data Logging: Stores 10,000 data sets with timestamps and site info

  • USB Connectivity: Transfer data easily to PC

  • Calibration Tracking: View most recent calibration data and date directly on-screen

Parameters Measured (Model U-52):

  • pH, pHmV, ORP, conductivity, dissolved oxygen, temperature, salinity, total dissolved solids (TDS), specific gravity of seawater, turbidity

This robust meter is ideal for professionals conducting environmental monitoring, water resource assessments, and compliance testing in the field.

Note:
*Battery life based on continuous operation using alkaline C dry batteries when the monitor temperature is over 20℃ and the backlight OFF.
*Accuracy is measured by calibrating 4 points for turbidity and electrical conductivity and 2 points for all other measurements against standard solution.
*Repeatability is measured by the ability to reproduce the results against the standard solution (at 25℃ normal pressure condition).
