Mudder TDS Meter 0-9990ppm and Temperature Water Tester
Product description:Dual TDS Meter allows you to measure TDS and Temperature level, at any time and any places.
How to Calibrate:
The meter take Virtual resistor calibration, It is convenient. In normal, it doesn't need to calibrate. If you want more accurate, you can calibrate it follow below:
Step 1: You need one accurate meter as sample, and make up 342ppm NaCl solution (or you can use the TDS calibration fluid)
Step 2:Pull sample meter and this meter in 342ppm NaCl solution, set this meter
Step 3: Hold TEMP button 3-5 second until the record flash on the screen
Step 4: TEMP button is down, and HOLD button is up, adjust the record the same as the sample meter
TIPS:
- Once the readout stabilizes(in 10 second),hold button to view out of the water
- If the tester displays a flashing "X10" icon, multiply the reading by 10

- Tester is not meant to be used in hot water (More than 99 degrees)
- How to Clear: Press "ON/OFF" twice, clear the data for each test, if you want test continuously
