How to Use Remove the protective cap First clean the electrode with distilled water, then put it aside until it's dry Immerse the pH meter electrode in solution being tested up to the minimum immersion level and not be over the maximum immersion line Turn on the pH meter by "ON/ OFF" button Stir gently and wait until the display stabilizes, and you can read the value After use, switch it off, use the distilled water to clean the electrode and replace the protective cap Recalibration In normal, this pH meter is factory calibration, and no need to recalibrate. Recalibration is required in the following conditions: - Lengthy periods of inactivity - Very frequent use - The testing accuracy requirement is very high - The "CAL" (calibration) button was pushed and electrode exposed to air for extended period of time Tips The glass bulb of the electrode is fragile. Treat it carefully. Don't touch it by hard tools and fingers. Suck the water on it gently when cleaning Clean the electrode with distilled water every time before and after use Open the battery case or replace battery, then you need to recalibrate the meter Specifications Measure Range: 0.00-14.00 pH Resolution: 0. 01 pH Accuracy:±0.01 pH Automatic temperature compensation: 0-50℃/ 122℉ Button battery: 2X 1.5V LR44 (included) Product dimensions: 15×2.8×1.3cm/6×1.1×0.5 inch Net weight: 52g/ 1.83 ounce Package included 1 X Meter 1 X Instruction 2 X Calibration buffer packets 1 x Carrying case

Manufacturer: Whirlping Brand: HY-PURE Model: HY-TDS Color: White

HY-PURE Digital TDS Meter To instantly check your overall water quality, TDS = Total Dissolved Solids, are the total amount of mobile charged ions, including salts or metals dissolved in a given volume of water. This pocket-size unit is also ideal for home or laboratory hydro-electrical conductivity testing. TDS, which is based on conductivity, is expressed in parts per million (PPM) or milligrams per liter (mg/L). TSD includes any inorganic element present other than the pure water molecule (H2O) and suspended solids. TDS affects drinking water quality consumption. For drinking, the lower TDS level of the water, the better for your health. Instructions: 1. Remove the cap from the pen and turn the switch on. 2. Dip the pen into the test solution but not more than 2cm. 3. Stir the pen in the solution, then stay stable and after 2-6 seconds the TDS value will display on the screen.Press the hold button to save the value and then look at it. 4. After using, dry the head the of the pen and put the cap back on. 5. The U.S.EPA`s Maximum Contaminant Levels of TDS for human consumption is 500ppm. Please note: The body of the TDS pen should not be exposed to liquids, direct sunlight or high temperature. Avoid dropping it. Parameters 1. Range: 0-9990ppm. 2. Accuracy: TDS ≤ 100ppm, ± 2ppm.TDS > 100ppm, ± 2%. 3. Battery: 1000 hours for continuous testing. 4. LCD display: 11*12mm. 5. Temp: 0~99℃ (32-212°F), accuracy ±0.1℃. 6. Size: 150*28*15mm (5.91*1.10*0.59in). 7. Net Weight: 53g (1.87 oz.). 8. Dual range: measures from 0-999ppm, with a resolution is 10 ppm, indicated by drinking*10 image, factory calibrated.
