TDS Water Tester .Patea Three-in-One Professional combination TDS Meter,TDS EC/Temperature Meter/Pen. Accurate and Reliable Water Test Meter. TDS (Totally Dissolved Solids)

Patea TDS-EC:
Professional quality combination TDS Meter, TDS EC Meter and Temperature Meter.
Ideal for all water quality testing, water purification applications, waste water regulation, aqua culture,hydroponics, laboratory and scientific testing, pools & spas, ecology testing, colloidal silver, water treatment and more.

Features:
* Lock function - makes it easy to read and record, press HOLD button then remove from test solution.
* 4 Display modes: press SHIFT button: TDS - ppm & °C, EC - μs/cm & °C, TDS - ppm & °F, EC - μs/cm & °F.
* 5 minute Auto Shut Off feature, so battery won't run down.
* Measurement Range: Conductivity: 0 - 9990 μs/cm TDS: 0 - 5000 ppm (parts per million) Degrees Celsius: 0.1 - 80.0°C, Fahrenheit: 32.0 - 176.0°F
* Accuracy: ± 2%

Usage:
1) Please unplug the electrode sleeve before use
2) Press the switch, place the electrode in the test solution and shake it gently.
3) After the numerically stable, press the "HOLD" button and take it out of the solution to read.

Shift between TDS & Conductivity:
The factory default TDS data, if the conductivity data of the solution is needed, please touch the SHIFT button, the instrument automatically shifted.
Automatic temperature compensation:The instrument with automatic temperature compensation function under measurement mode.
Temperature shift:Continuous touch the SHIFT button twice, degrees Celsius and degrees Fahrenheit conversed, the factory default degrees Celsius

Note:
1. Avoid heat, direct sunlight.
Please adopting standard buffer solution calibration, incorrect calibration would cause measurement error, thus affecting the accuracy of the test solution, or cause the instrument not working properly.
3. Do not thrown the instrument into the test solution to avoid the circuit board short circuit.
