Frequently Asked Questions What does a TDS meter actually measure? A TDS meter measures the electrical conductivity of the water, which is caused by dissolved substances. This is used to calculate a value for the total amount of dissolved solids. It is important to note that the meter only displays the quantity of dissolved substances, not their type or purity. A high TDS value therefore does not automatically mean that the water is contaminated or unhealthy – nor does a low value guarantee that the water is free from pollutants. Measurement range: 0 to 1990 ppm (mg/l) What does TDS mean? What is ppm? TDS stands for Total Dissolved Solids – that is, the total amount of all dissolved solids in the water. These include minerals, salts, metals and organic substances dissolved in the water. The concentration of these dissolved substances is given in milligrams per litre (mg/L) or parts per million (ppm). Is it easy to use, even for beginners? Yes. Switch it on, dip it in the water and read the value straight away – no prior knowledge required. How accurate are the measurement results? For everyday use, the readings are reliable and provide a good indication of water quality. Can I use the tester when I’m out and about? Yes, the device is compact, lightweight and fits easily into any bag. Who would particularly benefit from buying this?

The XS Instruments Cond 7 Vio and 70 Vio multi-parameter hand-held measuring device with innovative high-resolution colour display is suitable for working in all conditions and offers you an integrated user-friendly guide in the form of the set-up and calibration mode. This allows the user to easily and intuitively use the instrument at any time. The combined portable conductivity, total dissolved solids, salinity (70 Vio only) and temperature meter of the Vio series has an automatic, up to five-point, conductivity calibration for the most common conductivity calibration standards. You are supported by an intuitive symbolism on the backlit screen, including the indication of the measurement stability (adjustable) and any errors. Another advantage is that the multi-parameter meter is delivered in our professional measuring case, which contains the measuring electrode, as well as our respective buffer solutions and the instructions. Complementary advantages of the 70 Vio version: GLP functions: Date and time, recall of calibration data and "Calibration due" function Integrated data logger for up to 1000 data, automatic and manual PC connection via USB for evaluation of measurement data (Micro-USB on the instrument side) via Data Link+ software Automatic brightness control of the display (prolongs battery life) Only 6 keys for easy control of all functions of the unit 230V power supply unit Manufacturer article number: 50110512
