A low-cost, high accuracy range of instruments to measure SV, CTD, pressure and temperature.
High-accuracy Multiparameter Sondes for monitoring turbidity, chlorophyll, DO and many other parameters.
A range of sensors for measuring chlorophyll, turbidity, level and temperature.
Multiparameter handhelds specifically designed for field work.
A range of standalone optical backscatter turbidity sensors
An intelligent active probe, designed for direct measurements of sound velocity in water using an innovative technique that measures 'time of flight' of a single acoustic pulse.
A lightweight, rugged, intelligent profiler which records high resolution sound velocity profiles of a water column to depths of 5000 m.
The Hydrolab Conductivity sensor uses four graphite electrodes in an open cell design to provide extremely accurate and reliable data with virtually no maintenance.
The Hydrolab temperature sensor is a 30k ohm variable resistance thermistor. The temperature sensor is included with every Hydrolab sonde.
For complete water quality sonde set-up and real time monitoring, the Surveyor is a simple and rugged handheld display that is designed specifically for use with the Hydrolab DS5X, DS5, and MS5.
The Minos SVP was designed for Ocean Professionals completing vertical profiling from small launches or boats. It is the only profiler on the market that can be entirely fitted with Xchange sensors, meaning that all sensors can be swapped in the field. The instrument need never return to the factory for calibration.
Designed specifically for use on mobile platforms by AML. The low power requirements make the Smart CTD a natural choice for systems on tight power budgets.
Capable of long term measurement of up to 15 water quality parameters simultaneously in surface waters, ground water and wastewater areas in severe fouling environments.
Hydrolab's high-stability, custom-made pressure sensors with four range options.
Hydrolab's Self-Cleaning Turbidity sensor measures from 0 to 3000 NTU and includes a user-programmable cleaning system to remove any fouling or debris that could otherwise affect readings.
Hydrolab's 4-Beam Turbidity sensor is compliant with 4B-GLI Method 2 and perfect for profiling or spot-check turbidity measurements.
Second generation Hach LDO sensor technology
The Hydrolab Dissolved Oxygen sensor is based on a standard Clark Cell design, which is EPA approved, and has been trusted for over 30 years.
Hydrolab provides the most accurate Chlorophyll a sensor available on a multiprobe.
Hydrolab provides the most accurate Blue-Green Algae sensor available on a multiprobe.
Hydrolab provides the most accurate Rhodamine WT sensor available on a multiprobe.
The Hydrolab pH sensor uses glass bulb and refillable reference electrode for reliable data from a sensor that is easily maintained and long-lasting.
Hydrolab's ORP sensor uses a simple platinum band that donates or accepts electrons to monitor chemical reactions, quantify ion activity, or determine the oxidizing or reducing properties of a solution.
Hydrolab's Ambient Light sensor, also called a Photosynthetically Active Radiation (PAR) sensor, provides a measurement of sunlight intensity at a specified point in the water column.
Critical functionality for set-up and download of most OTT Level instruments, OTT Meteorological instruments, and Hydrolab Series 5 sondes available via a PDA.
