Aquameter™

A sophisticated, easy to use water quality test meter for fast and accurate water quality measurements including dissolved oxygen, conductivity, turbidity, temperature, pH and ORP.

Used with any one of eight multiparameter probes readings are simple and easy to obtain as every second the data is sent to the meter, where it is processed for display along with atmospheric pressure, position and altitude information.

The unit can be set to log at regular intervals or data can be immediately displayed. Collected information can be transferred to a PC or laptop into the most popular spreadsheets as well as Google™ Maps and Google™ Earth, where the readings can be overlaid onto maps or satellite photos.

Aquaprobe™

At just 42mm in diameter to fit down 2” wells the Aquaprobe™ , built from marine grade aluminium and stainless steel is available in 10 different versions to cover everything from pH testing to comprehensive water analysis, even in the harshest conditions.

Probes can include optical DO technology and a sensor for absolute depth measurement as well as level monitoring.  Each probe has a 3m (10') cable and waterproof plug assembly and removable protective sleeve. Individual electrodes are factory fitted with the exception of the pH electrode, ORP or combined pH/ORP electrodes which are replaceable. Up to four electrodes can be mixed and matched in order to provide eight different options.

The fully waterproof probes have threaded stems to allow bracket or extension pole mounting.

Telemetry system available

AquaLogger™

For remote data logging the rugged Aqualogger™ is compatible with all Aqua probes and will provide up to 6 months continuous recording. It will log up to 32,000 complete sets of data for each sensor. It has programmable event triggers and an intuitive Windows interface to allow for easy data retrieval.

AquaPlus™

AquaPlus™ is an advanced, high precision portable Optical Dissolved Oxygen measurement system for field use. Compact and strong it has been designed to give maximum performance over the long term.

It contains a barometric sensor and an optical DO sensor, plus a precision temperature sensor and an electrical conductivity (EC) sensor. From measurements taken by the EC sensor, the salinity of the sample can be accurately determined, plus Resistivity (RES), Total Dissolved Solids (TDS) and Specific Seawater Gravity (SSG).

The AquaPlus™ meter will record up to 2000 sets of readings tagged with time, date and position can be taken and downloaded to most popular spreadsheets as well as Google™ Maps and Google™ Earth, where the readings can be overlaid on maps or satellite photos.

Van Walt Telemetry System

By combining a logger and a data converter with our telemetry system we can offer an onsite solutions for data collection of parameters such as depth, turbidity, pH, ORP, EC, RES, DO, TDS, SAL, SSG, Temperature and barometric pressure for both surface and groundwater applications.

This cost effective system is suitable for short or long term unattended deployment providing accurate results set at whatever intervals your research requires relaying the data back to your office based PC.
