HL4 Multi-Parameter Water Quality Meter
The HYDROLAB HL4 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
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 HL4 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 HL4 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
With the following output interface, the Hydrolab HL4 is able to easily integrate into real time telemetry systems:
• SDI-12
• RS-485
• RS-232
• USB
- FEATURES
-
- Self-monitoring system reports the status of the instrument, flags the data, and shows the user where the problem is with assistance on how to solve the issue
- User-scheduled calibration and maintenance intervals indicate when they are due
- Guided and semi-automated calibration routines lead the user through the calibration process
- Calibration results are stored with date and time, calibration type, user identification, and user notes
- Check Calibration process allows the user to verify calibration and store the results
- Calibration reports contain information about previous calibrations and calibration checks
- Sensor status is saved with every line of data and is contained in the log file
- Dedicated communications modules allow easy integration with data loggers and telemetry systems
- Compatible with the Surveyor HL – a fully IP67 handheld designed for field use with a full-color screen that is visible in direct sunlight
