bulletAustralian Made
The Aqua-DP is a waterproof, easy-to-use, Dissolved Oxygen, pH/mV and Temperature meter. It provides accurate, reliable measurements, and is very easy to use.

Genuine one-touch calibration puts an end to time-consuming calibration procedures.

Rugged and Reliable
TPS has used the latest microprocessor electronics to totally eliminate all internal and external adjustments. The result is a dramatic increase in reliability. The unit is ideal for field or factory use.

The Dissolved Oxygen and pH sensors are designed for maximum durability in field and factory environments.

24 Character Alphanumeric Display
The two-line, 24 character display shows the Dissolved Oxygen  plus pH readings simultaneously. Alternatively, a Large Digit mode is available. This shows one reading at a time at almost double the size. To simply use of the Aqua-DP, plain English prompts and error messages are provided. There are no codes to interpret like some other brands.

One-touch Calibration
Calibration of the Aqua-DP could not be simpler. 

Just place the sensor into the relevant standard and press the Calibrate key. That's all there is to it !

The Aqua-DP displays sensor condition after calibration has been completed, allowing for preventative maintenance.

All calibration information is stored in memory when the Aqua-DP is switched off, even if the battery is removed.

Salinity Correction
Salinity correction for ppM Dissolved Oxygen readings is a breeze. Simply enter the Salinity value and the Aqua-DP does the rest !

Low Battery Drain
The Aqua-DP will provide in excess of 70 hours of continuous use with an alkaline 9 volt battery.

A handy battery-saver function switches the Aqua-DP off after 5 minutes if no keys have been pressed. This function can also be disabled for continuous operation.

Temperature Compensation
Correct temperature compensation is vital for accurate Dissolved Oxygen measurements. The Aqua-DP compensates for membrane permeability for all readings and also for Dissolved Oxygen solubility in ppM mode.

Temperature compensation for pH probe performance is also fully automatic.

Australian Quality
The Aqua Series is proudly designed and manufactured in Australia. Our aim is to provide you with the best quality, service and value for money. The TPS Quality System has been certified in accordance with the AS/NZS ISO 9001 standard. Since 1968, TPS has built a reputation for excellent backup service that is second to none.
