HORIBA Multi Parameter Water Quality Analyzer

Product Introduction

HORIBA Multi Parameter Water Quality Analyzer

Product Performance

• High sensitivity turbidity probe (U-52, U-53)

• The dissolved oxygen probe is easy to maintain, and the filter membrane comes with a nut for convenient on-site replacement

• Handheld transmitters and sensor probes are easy to operate with one hand, making operation and data confirmation effortless

• The single key calibration operation makes it easy to maintain parameters such as pH, dissolved oxygen (DO), conductivity, turbidity, and water depth
