HL7 Multi-Parameter Water Quality Meter

The HYDROLAB HL7 multiparameter sonde is a world class water quality meter suitable for spot check or unattended water quality monitoring.

Versatile and durable, the Hydrolab HL7 has a large sensor suite including:

• Temperature
• Conductivity (EC)
• Salinity (SAL)
• pH
• Oxidation-Reduction Potential (ORP)
• Dissolved Oxygen (LDO)
• Depth
• Turbidity
• Nitrate
• Chloride
• Chlorophyll a
• Blue Green Algae
• Rhodamine
• Ammonia
• Total Dissolved Gas
• Phycoerythrin

When measured in real time, results can be viewed on the Hydrolab Surveyor handheld display: Surveyor HL – Aqualab

Designed for water quality professionals, the Hydrolab HL7 is able to thrive in demanding environmental conditions. Bio-fouling is minimized when equipped with the central cleaning brush and performance is maximized with an advanced power management system.

Various cable lengths are available with all Hydrolab HL7 models:

• 2 meter
• 5 meter
• 10 meter
• 15 meter
• 25 meter
• 25 meter
• 30 meter
• 50 meter
• 75 meter
• 100 meter
• 150 meter
• 200 meter
