Digital Water Quality Meter 4 In 1 Measuring Instrument PH Meter Water Quality Test Kit Water Quality Tester ORP Meter Redox Potential Meter Automatic

---------------------------------------------------------------------- 🟢【4 in 1 Water Quality Meter】PH/ORP/H2/Temperature meter is used to measure PH, redox potential (ORP), H2, temperature (C°/F°). It can be used for various purposes such as checking the disinfecting power of reduced tea, reduced water, hydrogen water, pool water, and acidic water. It has an automatic temperature correction function, which allows you to read more accurate readings by adjusting it according to the water temperature and water quality. 🟢【LCD display/automatic auto-off function】 Adopts a large LCD display screen, making reading convenient and more accurate. LCD Large digital display that is easy to read and understand at a glance. It also has a backlight function, making it useful at night or in dark places. Automatically turns off after 5 minutes of no use to save battery. 🟢【High Precision and Accurate Measurement】This measuring instrument has upgraded electrodes and has higher performance. Increased accuracy and stability, which allows you to measure more accurate pH/EC/TDS/Salinity/Temperature values. The temperature sensor is installed in the measurement part and is made of NTC material to ensure measurement accuracy and minimize measurement errors due to temperature changes. Both pH and EC have 3-point calibration (calibration agent not included) 🟢【Easy to operate】Press the power button, select the measurement mode, then dip the electrode into the solution, shake it several times, wait for a while, and you will get the measurement value. Once the measured value is stable, simply press the HOLD/TEMP button to lock the measured value, which is very easy. It also comes with an original Japanese instruction manual (which includes proofreading methods and precautions for use), making it easy to use. 🟢【Wide range of applications】High-precision algorithm chip and electrode of digital water quality meter, 4 items "pH, ORP (oxidation-reduction potential), H2 (dissolved hydrogen), temperature" to ensure accurate and quick response measurement, applicable to water quality monitoring, aquariums, aquaculture, hydroponics, salt baths, laboratories, scientific research, industry, pools, etc. IP 65 waterproof rating (battery cover needs to be twisted) is suitable for rainy days and sudden drops into water.
