Description
The TDS3-K TDS meter with thermometer and calibration is a pocket-sized device for quick checking of the total amount of dissolved substances in water and its temperature. It is ideal wherever regular water quality control matters: at home, by a water filter, in water treatment installations, as well as with systems such as reverse osmosis, an osmosis filter, or a water filtration system. The TDS3-K model offers a HOLD function with an audible save confirmation, a clear LCD display, automatic shut-off after 10 minutes of inactivity, factory calibration, and manual calibration with a mini screwdriver. The set includes a case with a clip, batteries, and an instruction manual.
What is the TDS3-K meter used for?
The device is designed to measure the total amount of all substances dissolved in water and the temperature. Thanks to its compact design, it can be conveniently used as a handheld tester for daily checking of drinking water, filtered water, and water from systems such as reverse osmosis filters.
The meter allows you to quickly verify the reading in ppm, which is especially useful when checking filter cartridge performance, monitoring the effectiveness of water treatment devices, and comparing water quality before and after filtration.
Main features and benefits
- measurement of the total amount of dissolved substances in water and temperature,
- HOLD memory function that saves the reading for later review,
- audible signal confirming the saved result,
- large, easy-to-read LCD display,
- built-in electronic thermometer,
- auto-off battery saving function,
- automatic shut-off after 10 minutes of inactivity,
- stopping operation when the properties of the tested water do not change for 3 minutes,
- factory calibration,
- manual calibration possible with a mini screwdriver,
- elegant gift case with clip,
- 2-year warranty.
Convenient everyday use
The TDS3-K was designed for simple and quick readings. The memory function allows you to freeze the result so it can be read at a convenient time. After saving the measurement, the device emits an audible signal, which makes everyday use easier.
If the properties of the tested water do not change for 3 minutes, the meter stops working. In addition, to save energy, the device turns off automatically after 10 minutes of inactivity. This is a practical solution for people who regularly check water at home or with a reverse osmosis system.
For readings above 999 ppm, the symbol [x10] appears on the display. The reading range is 0-9999, and the meter measuring range is 0-9990 ppm.
Calibration and measurement stability
The meter is factory calibrated, so it is ready to use straight out of the box. The device was calibrated with a 342 ppm NaCl solution. For users who want to adjust the settings themselves, manual calibration with a mini screwdriver is available.
Automatic temperature compensation in the 1-50°C range helps maintain reliable readings when the temperature of the sample changes.
In practice, a TDS meter works best as a control tool for comparing water quality and monitoring filtration performance. It is a convenient solution for regular checking of water after devices such as a water filter, an osmosis filter, or a reverse osmosis system.
Equipment and build
The TDS3-K model has a handy pocket-sized form and comes with an elegant case. The case has a clip, so the meter can be easily carried and stored. The built-in electronic thermometer extends the device’s functionality and allows you to check not only TDS, but also water temperature.
The LCD display used is large and easy to read, which makes operation easier both at home and during quick measurements at different sampling points.
