Accuracy test

OverviewThis is a pocket-sized 3 5/6-digit automatic digital meter. It has stable performance, high precision, high reliability, clear reading and overload protection. Driven by AAA 1.5V battery, the instrument adopts large screen LCD display and adopts boost power supply. Even at the edge of 2.3V low battery, it can ensure the high brightness of backlight and flashlight. The meter is easy to carry and is very popular among users. The instruments backlight can be turned on and off automatically after 15 seconds. This series of instruments can be used to measure DC voltage and AC voltage, AC and DC current 600A, resistance, capacitance, diode, temperature, continuity test, square wave output, frequency measurement and true RMS. It is a superior tool and an ideal tool for laboratories, factories, radio enthusiasts and families.Features:Function DC voltageDCV√AC voltageACV√DC currentDCA√AC currentACA√Resistor / Diode / On-Off Test / Capacitor√Frequency F√Square wave output√NCV√Full unit symbol√Backlight manual/Auto off√True RMS measurement√Temperature(℃/℉)√Flashlight lighting√Specifications:1.DC voltage (DCV)Accuracy Range6000countsResolution6V±(0.5%+3)0.001V60V0.01V600V0.1V1000V±(0.8%+10)1V2.AC voltage(ACV)AccuracyRange6000countsResolution6V±(0.8%+3)0.001V60V0.01V600V0.1V750V±(1.2%+10)1V3.DC current (DC A)AccuracyRange6000countsResolution60A±(2%+30)0.01A600A0.1A4.AC current(AC A)AccuracyRange6000countsResolution60A 0.01A600A0.1A5.Resistance (Ω)AccuracyRange6000countsResolution

Features: ★Scientific method of planting - how do I know the pH of the soil? How do I know the humidity of the soil?How much light is appropriate? Now the 3-in-1 soil tester gives you a direction.★Easy to use: The soil test kit no battery needed, insert the sensor probe into the soil,leave about 1 cm on the top of the probe, toggle the switch to test the moisture, pH and sunlight.Please wait a few minutes until the pointer stops swinging to get the dial Stable readings.If the plant is very dry, the soil pointer will not data, which means your plant needs water.★Wide range of use: Suitable for indoor and outdoor use, lightweight and portable design,suitable for home plants, gardens, lawns and farms,the 3-in-1 ★Moisture Sunlight pH soil test helps you to become an excellent plant grower.★Accurate and reliable: Double-needle detection technology greatly improves the speed and accuracy ofdetecting and analyzing soil moisture and pH acidity, and the correct culture method promotes healthy growth of plants.(Note: If the soil is too dry, the tester has no data, or the data is not accurate)Package Included: 1 x Soil Tester Light Detector Soil Acidity PH Meter Thermometer.Please Note:1. Please allow 1-3cm error due to manual measurement.2. Please understand that colors may exist chromatic aberration. Thanks for understanding!

✔SPECIFICATION- Brand: Tvird- Measuring Range: 0.00 -14.00 pH- Resolution: 0.01 pH- Accuracy: ±0.01 pH- Batteries: 2*1.5V (Button cell include)- Operating Temperature: 0-70℃- Dimension: 152mm*28mm ✔OPERATION1. Remove the protective cap and protective film on the screen.2. Rinse the electrode with distilled water, and suck it with filter paper. 3. Turn on the meter, immerse the pH meter electrode into the test solution.(can not be over the immersion line) 4. Stir gently and wait about 30s for the reading to stabilize. 5. Turn off the meter after use, clear the electrode with pure water and dry it with filter paper. ✔Note*The meter was calibrated before off the factory. Do not need to calibrate the meter when first use. *The glass electrode is fragile, treat it carefully. Dont touch it by hard tools or fingers. *Please do not immerse the meter into the solution over the "warning line", to avoid damage to the circuit board. *If the "cal(calibration) button is pressed and electrode exposed to air for a long time,calibration is required.
