By Tom Calder

- What it tests
- Total dissolved solids (TDS) only
- Format
- Handheld digital meter, LCD, wallet case
- Tests included
- TDS + temperature °C/°F, ±2% accuracy
- Results in
- Instant (seconds)
This gives an instant total-dissolved-solids reading in parts per million, which is genuinely useful for tracking a water softener, filter cartridge or reverse-osmosis system over time. It tells you nothing about lead, bacteria, nitrates or anything else that actually determines whether water is safe to drink.
- Best for
- Plumbers, filter/softener owners and private-supply checks who want a quick, repeatable TDS reading — not a safety test.
- Skip it if
- You're checking lead risk in a pre-1970s house or the safety of a private borehole/spring supply

Researched, not used. We haven't used this product. This review is built from the maker's specifications, owner reports and our own sizing.
What we like
- Instant, one-touch reading with no reagents or waiting
- Cheap and pocket-sized — handy for spot-checking filter/softener performance
- Simple LCD display with °C/°F temperature readout, includes batteries and a case
Worth knowing
- Measures TDS only — no indication of lead, bacteria, pesticides or hardness minerals specifically
- A low or high ppm number doesn't by itself mean water is safe or unsafe

Who shouldn't buy this
Don't buy this if you're checking lead risk in a pre-1970s house or the safety of a private borehole/spring supply — a TDS meter can't answer that; use a UKAS-accredited lab test kit instead.
This is a Researched review: we haven't used this product. We check every specification against at least two independent sources, re-check the UK price on a schedule where we can track it automatically, and say plainly who it isn't for. Commissions never change a rating.
If this isn’t the one
Best for Owners of a private well, borehole or spring wanting a broad lab panel with UKAS-accredited bacteria results, or buyers vetting a private supply before a house purchase.
Best for Homeowners with pre-1970 lead pipework, or anyone on a private supply (borehole, spring, well) who needs a definitive lead reading rather than an indicative guess.
