3 in 1 TDS EC Temperature Meter Digital Water Tester Pen

Checking the quality of your drinking water has never been easier. This 3 in 1 TDS, EC and temperature meter is a compact digital water quality tester designed to measure total dissolved solids, electrical conductivity and water temperature in a single pen-style instrument. Whether you are monitoring a home water filter, comparing tap and bottled water, or simply want to understand what is in your water, this portable tester gives you quick, readable results with a TDS range of 0 to 9990 ppm.

• Three functions in one pen: measures TDS (in mg/L or ppm), electrical conductivity (in µS/cm) and temperature.
• Wide TDS measurement range of 0 to 9990 ppm, suitable for a broad variety of water samples.
• Hold function saves a reading on screen so you can easily read and record results after removing the probe from the solution.
• Auto-off feature switches the meter off after 10 minutes of non-use, helping to conserve the battery.
• Compact pen-type design makes it easy to carry and use wherever you need to test water.
• Includes a black leather carrying bag to help keep the meter protected during storage and travel.

Total dissolved solids, or TDS, refer to the inorganic salts and organic matter present in a liquid. Because TDS is expressed in milligrams per litre or parts per million, it provides a practical indication of how much material is dissolved in your water. Electrical conductivity, measured in microsiemens per centimetre, reflects the water's ability to conduct an electrical current, which is closely related to its dissolved content. Using these two readings together with temperature gives you a clearer overall picture of your water sample.

This digital portable water quality tester is useful for households that rely on filtered water, offices with drinking water dispensers, and anyone who wants to keep an eye on the purity of the water they consume. Many people search for a reliable TDS meter for drinking water, a portable water purity pen, or an affordable water filter tester, and this device is designed to answer those needs with a straightforward, handheld tool. It can also be a helpful companion for those learning about water quality at home.

To help you interpret your results, the product's reference guide outlines general ranges for TDS readings. Water measuring 0 to 50 ppm is classed as high purity water, while 50 to 100 ppm is considered pure water. Readings between 100 and 300 ppm indicate general pure water, and 300 to 600 ppm may leave incrustation scale. Water between 600 and 1000 ppm may have a bad taste, and readings above 1000 ppm are noted as not suitable for drinking. These guidelines make it easier to understand what your measurements mean in everyday use.

Operation is simple. Dip the probe into the water sample, wait for the reading to stabilise, and press the Hold button if you want to freeze the value for reading or recording. The lock function makes it convenient to note down results even after the meter has been removed from the test solution. The meter is powered by a single 3V CR2032 battery, which is included in the package, so you can start testing straight away.

The package includes the 3 in 1 TDS and EC meter, a black leather bag, one CR2032 battery and a user manual. The product is brand new and comes with the components listed above, giving you everything needed to begin measuring water quality right out of the box.

If you are looking for a practical, portable tool to check your water's TDS, conductivity and temperature, this 3 in 1 digital pen tester offers a convenient way to keep track of water quality at home, at work or on the go.
