01MEASURING TOOLS & SENSORS

Precision for every drop

A slender instrument that transforms the invisible chemistry of water into clear, legible data. It sits comfortably in the hand, ready to probe the clarity of your aquarium or the purity of your tap.

This three-in-one meter reads total dissolved solids, electrical conductivity and temperature simultaneously. It suits aquarists, laboratory technicians and anyone who values exactness in their hydration or irrigation.

02DESIGN

A compact tool for detailed inspection

Housed in lightweight ABS, the pen-style form factor is designed for one-handed operation. The device integrates three distinct sensors into a single unit, eliminating the need for separate instruments. Its slim profile allows it to reach into narrow containers, test tubes or tight corners of a filtration system without disturbing the sample.

03DISPLAY

Two-tone feedback for instant clarity

The screen utilises a dual-colour backlight system to communicate status at a glance. Under normal conditions, the readout glows in a calm green, signalling stable parameters. When values shift towards higher concentrations, the display shifts to red, providing immediate visual feedback without requiring the user to memorise specific thresholds or interpret complex graphs.

04FUNCTION

Three modes for versatile measurement

The meter offers four distinct operational modes, allowing users to isolate or combine TDS, EC and temperature readings as required. With an accuracy margin of plus or minus two percent, it provides reliable data for both casual monitoring and more rigorous testing. The resolution reaches one part per million for solids and one microsiemens per centimetre for conductivity.

05PRACTICALITY

Simple power and packaging details

Powering the device requires two LR44 button batteries, which are not included in the factory pack. The unit arrives in a compact carton measuring 20 by 15 by 2 centimetres, weighing just 0.15 kilograms including the manual. This small footprint makes it easy to store in a drawer or carry in a pocket during routine maintenance sessions.
