High Accuracy & More Sensitive Bulb Design PH Meter: The core of the ph tester digital is the electrode, and the core of the ph tester electrode is the bulb. The ppm meter bulb made by blue effect technology is blown at a high temperature of 1000 degrees Celsius. This can fully respond to the H+ ions in the solution.The bulb glass film uses a low-impedance glass sensitive film (25MQ), and the reaction speed of the TDS PH meter is also greatly improved, reaching a true level of 0.01 PPM Meter with One Key Lock Value Function : When the measured value is stable, just press the HOLD/TEMP key to lock the measured value and take it out for viewing, which is really simple. (Before press "HOLD/TEMP" key, the number of pH is fluctuate slightly which is normal.) Easy to Use Lab PH Meters with Backlit LCD Design : Just remove the ph pen protective cap and immerse the ph water tester electrode in the solution and press the button to be measured. Don't worry about seeing the displayed value when there is insufficient light. Water ph tester features a green backlit LCD to help you see the measurement clearly in any situation. TDS Meter with Automatic Temperature Compensation: Temperature can affect reading levels, our water meterr's automatic temperature compensation can ensure that you're getting the best possible reading. Unlike other ph meter for water hydroponics that only have a range of 0 C-50 C, ours ph meter for water hydroponics has a even better range of 0 C-60 C (32 F-140 F) , so you can test with confidence in any environment. PH Tester with Wide Application: Ideal for household and laboratory pH testing applications, including drinking water, swimming pool, pond, beer brewing, kombucha, aquariums, hydroponics, laboratory, food processing etc. (Range: 0.01 - 14.00pH; Resolution: 0.01pH; Accuracy:0.05pH; TDS range: 1-9990ppm; Resolution:1ppm; 0.1ppt; Accuracy: 2% F.S. ), reliable and quick readings. More description TDS Meter Digital Water Tester 3-in-1 pH Meter: water quality tester has a three-in-one function, which can measure PH, TDS and temperature with high precision. All-round measurement of water quality to ensure healthy water quality. The water ph meter is an ideal gift for family and friends. Due to Recently Reviews about 1413 Solution, please note that TDS Meter had been calibrated by 1413 solution in advance; You can use it directly and it could last for 1 year without second calibration; So 1413 calibraiton solution is not included PH Meter for Food with Safety Perforation Design The Portable tds water tester compact design can be carried around, and the safety perforated design on the top can also save space when hung. PH Tester Water with Full Waterproof Design IP67 Fully waterproof rubber ring design, IP67 waterproof level, each part of the product will have a sealing ring. Digital Ph Meter with Built-in Buoyancy After ph meter for water 0.01 digital ph enters the water, it will immediately rise for easy salvage. PH Meter for Water Hydroponics with Ceramic Temperature Electrode- Extremely fast and accurate measurement of liquid temperature, automatic calculation of temperature compensation. [Calibration PH steps of PH Meter Digital Water Quality Tester]: Step 1: Press the ON button to turn on Step 2: Press the TEMP / CAL button Step 3: Adjust to pH mode Step 4: Place the electrode in the pH 4.00/ 6.86/ 9.18 standard solution Step 5: Wait for the readings to stabilize(usually 5~10 Seconds) Step 6: Press and hold the TEMP/CAL button for 6 seconds, then you can see corresponding value flashing 3 times which means calibration of pH is completed. Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
