HL4 multiprobes
The Hydrolab HL4 is the next generation multiparameter water quality instrument from OTT Hydromet. Its reliability, ease-of-use, and metadata produce water quality data you can trust.
HL4 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
Applications:
For measurement of popular water quality parameters in:
- Freshwater rivers and streams, lakes and reservoirs, and groundwater wells
- Salt or brackish water bays, estuaries, and near-coastal areas
- Attended monitoring, continuous unattended and real-time monitoring
Available Sensors:
- Temperature, Conductivity, pH, LDO (Luminescent Dissolved Oxygen), Depth, Turbidity
Specifications:
- Diameter: 4.44 cm (1.75 in.) without rubber bumpers
- Length: 51.43 cm (20.25 in.) to 77.787 cm (30.625 in.) depending on configuration

Surveyor HL
The Surveyor HL is the handheld display that connects to the Hydrolab HL4 for attended monitoring applications and for completing other common tasks with the sonde in the field. It is rugged and compact with a color screen that is visible in direct sunlight and a keypad with pronounced buttons for system navigation.
The menu structure and functions are modeled after the Hydrolab Operating Software to make it easy to use and provide feedback about the system’s status and access to onboard metadata. The Surveyor HL is powered by a rechargeable lithium-ion battery that holds enough energy to power a Hydrolab HL4 for 10 continuous hours.
Surveyor HL Features:
- Fully IP67 enclosure with hand strap and rubberized case for optimal grip
- Threaded connector to securely attach the sonde deployment cable
- Color LCD 3.5 inch QVGA display visible in direct sunlight
- Rechargeable lithium-ion battery that can power an HL4 for 10 continuous hours.
Notes:
- The Surveyor HL is designed to operate with the HL4 multiprobe only. It is not compatible with any other multiprobes from HydrotTech or Hydrolab.
- The standard Surveyor 4A is also not compatible with the HL4 multiprobe.
- The HydroTech PC tablet Algix 10X-HT is fully compatible with the HL4 multiprobes.
Specifications:
- Graphical display:
- Color, LCD 3.5" QVGA
- Transflective (readable in direct sunlight)
- Power supply:
- Lithium-ion rechargeable
- Battery life: up to 10 hours continuosly on (20 °C)
- IP-Rating: Handheld meter: IP67
- Buoyancy: Positively buoyant in water.
- Dimensions
- LxWxH:21.8cmx9.4cmx5.3cm (8.6 in. x 3.7 in. x 2.1 in.)
- Weight: 0.68 kg (1.5 lbs)
- Operating temperature: –5 to 50 °C (23 to 122 °F)

Hydrolab Operating Software
The Hydrolab Operating Software is the PC-based application for interfacing with Hydrolab HL Series sondes, the Hydrolab Surveyor HL, and Hydrolab communications modules. It is designed for intuitive water quality data collection, sensor calibration, settings adjustment, and metadata access.
Features:
- Know your instrument is working correctly with instrument and sensor statuses that are shown
- Calibrate sensors and check sensor calibrations with guided and semi-automated calibration routines
- Monitor water quality data real-time or set up a log file for long term monitoring
- Access and create metadata that give system information, calibration history, user information, and site information
- Configure sonde, sensor, and communications settings
- Compatible with any recent version of a full Microsoft Windows Operating System on a laptop, desktop, or ruggedized device
