Are you after a budget-friendly TDS meter? You're in luck! Your team of scientists at Instrument Choice have systematically researched and curated a list of cheap TDS meters - all under $250AU. Each listing includes all the important details you need to know about each meter (such as the key specifications) to help you find the best meter for your budget.
What is TDS?
Total dissolved solids (TDS) is the metric of the combined content of organic and inorganic substances present in a liquid. The measurement excludes pure water or suspended solids. You express TDS measurements as an amount in a given volume of water, and you will see results displayed as either milligram per litre (mg/L) or parts per million (ppm).
For a true TDS measurement, you need to completely evaporate moisture from your sample and then weigh the solid residue. As this is often impractical, the most common and practical way to measure TDS is with a specialised conductivity meter.
TDS meters measure conductivity, then apply a conversion factor to approximate TDS. TDS-only meters do not display conductivity but still use electrical conductivity with a conversion factor to calculate results.
In a nutshell: The HI98302 is a rugged, reliable and the best-performing cheap TDS meter.
Special features & capability:
This unit offers quick and accurate readings of TDS and conductivity.
When calibration is necessary, you need only submerge the electrode tip into a calibration solution and adjust the trimmer on the tester's side – that’s it!
In a nutshell: A cheap all-rounder, the IC-TDS20 is a reliable TDS tester and provides excellent value for a range of routine TDS testing applications.
Special features & capability: The IC-TDS20 us equipped with Apera’s unique platinum black conductivity probe technology, ensuring a wider measurement range without compromising accuracy and consistency.
In a nutshell: Straightforward to use and backed by OHaus' reputation for quality, the IC-ST10T-A is a durable and cheap TDS meter guaranteed to provide years of accurate TDS measurements.
Special features & capability: Compact and portable, users can take their Starter TDS Meter wherever it’s needed to measure any organic and inorganic substances' combined liquified content.
In a nutshell: The IP67 rated waterproof TDSTestr11 offers dual or auto-ranging measuring options.
Special features & capability:
The IP67 TDSTestr11 allows you to measure more media using a single tester.
The meter has a long-lasting sensor with a sensing element made of SS316 stainless steel. If the sensor becomes damaged, it’s user-replaceable at a fraction of a new meter’s price. These features amount to a meter that is robust and long-lasting and offers years of fuss-free service.
