Now there's a handheld Conductivity, TDS and Temperature meter with automatic range selection, at a budget price. Genuine one-touch Conductivity and TDS calibration makes the Aqua-C very easy to use.

Linearised TDS values are calculated by the software, for maximum accuracy over a broad range. The standard Aqua-C kit includes electrode and standards, ready for immediate use. An optional hard carry case is also available.

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 electrode supplied is made of Ryton plastic for maximum durability and chemical resistance.

24 Character Alphanumeric Display
The two-line, 24 character display shows the Conductivity or TDS reading plus temperature simultaneously. A Large Digit mode is available, which shows one reading at a time at almost double the size. The Aqua-C is simple to use, 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-C could not be simpler. Just place the electrode into a standard Conductivity or TDS solution and press the Calibrate key. That's all there is to it !
The Aqua-C displays probe condition after calibration.
All calibration information is stored in memory when the Aqua-C is switched off, even if the battery is removed.

Automatic Range Selection
Automatic range selection simplifies use of the Aqua-C even further. When a measurement is taken, the Aqua-C automatically selects the range that will provide readout to the best resolution.

Low Battery Drain
The Aqua-C will provide in excess of 70 hours of continuous use with an alkaline 9 volt battery. 
A handy battery-saver function switches the Aqua-C off after 5 minutes if no keys have been pressed. This function can also be disabled for continuous operation.

Automatic Temperature Compensation
Correct temperature compensation is vital for accurate Conductivity and TDS measurements. The microprocessor in the Aqua-C therefore performs all temperature compensation calculations. 

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.
