Description Resolution: 0.01 pHDhe automatic calibration function ATC Heating: When the pH Electrode will be an electrode, conductivity measurement data and other devices a certain temperature deviation, the deviation will be generated over its 0.03pH / , such deviations are temperature dependent variation normally.Automatic temperature compensation is required, have an internal temperature sensor, pH sensor gives a compensated signal, The instrument has a pH value of direct temperature compensated .Automatic temperature compensation in a field environment for pH measurement is very useful. PH measurement on the device must have this function, with this function measured pH value will be more accurate. NOTE: Buffer powders are not included. Introduction This PH meter is the perfect device for determining the acid or alkalinity of liquids. It is incredibly easy to use, simply dip the electrode and the readings are displayed automatically. With 0.01pH resolution you can get higher accuracy than other pH meters. Electrode design has a higher durability to ensure longer service life. Applied range: the production and drinking of purified water, electroplating liquid, boiler water, water in fish tank, swimming pool water, photographic rinsing liquid, well water, deep water, laboratory, aquaculture, food processing etc. The device has not yet calibrated. You should buy calibration powder and then calibrate yourself. Properties 1.Fast and accurate readings: just turn it on, immerse and read the display,no need to work with color charts or test strips; Large LCD display makes it easy to read. 2.Automatic calibration:No need to adjust any screwdrivers, just finish the calibration with self-calibration button and included buffer powder. 3.ATC function: Automatic temperature compensation automatically takes into account temperature changes, Full measuring range of pH 0-14, 0.01 pH resolution. 4.Portable design:Hand pen type and compact carrying bag makes it convenient to fit into your pocket or pocket and go anywhere.5.Wide Application:Ideal for home and laboratory pH test applications, including drinking water, swimming pools, aquariums, hydroponics, etc. Specifications Display: LCD DigitalMeasurement range: 0.00-14.00pResolution: 0.01pHAccuracy: 0.05pHSPower supply: 2.1.5V LR44 batteries (store longer than 500 hours)Operating temperature: 0 .80 Calibration: automatic calibrationDimensions: 15.3 x 2.9 x 1.6 cmWeight: 52g Package Contents 1 x Digital PH Meter
