1. Detection ray type: beta ray, gamma ray, x-ray2. Detector: energy compensation GM tube (Geiger counter)3. Dose equivalent rate: 0.00-50000μ svh (50mSv/h)4. Cumulative dose equivalent: 0.00μ sv - 5000msv5. Sensitivity: 80 cpm / uSv6. Unit conversion: μSv/h, mR/h, cps, cpm7. Battery: 3x1.5V AAA battery (not included)8. The device uses a Geiger counter, which is an ionizing radiation detector capable of measuring beta rays, gamma rays and x-rays. The working principle is based on the ionizing properties of radiation in the gas. It consists of an ionization chamber or a small room that acts as a detector. When a certain voltage is applied to the detector, the radiation ionizes the gas, producing a pair of ions for each ionization event. This leads to the amplification of the ionization signal, which is then recorded by the electronic device to measure the amount of radiation per unit time.9. The high-definition backlit large screen provides convenient reading, suitable for use in various environments, and can remain clear even in the dark.10. Data saving function allows one-click locking of measured values, which facilitates data recording and viewing.11.

With Backlight Or Not:No Display Type:Analog Model Number:PH Paper is_customized:Yes Directions to Use:Remove a single test strip from the plastic container, holding it from the end with no colored pads.Dip the strip (all 4 colored pads) into the transparent liquid to be tested for 1 second. Depending on pH of sample, color will change almost instantly.Shake the strip to remove excess liquid.Match the color of the pads to the pH diagram on the box label to obtain the pH value of the tested liquid.A pH value of 7 is neutral. A pH value less than 7 is acidic, while a pH reading greater than 7 is alkaline.How to Interpret Water pH Test ResultsThe pH value of a particular water sample is obtained by matching the colors of the strip’s reagent pads after being dipped in the test liquid for approximately 1 second against the pH scale, and noting the corresponding number.Test results will vary between 0 and 14.0, and can be classified as acidic, neutral or alkaline.Acidic (0.0 - 6.0)If you test your water using a pH testing kit and the results are between 0 and 6, this suggests that the water could be acidic and soft with the potential to be corrosive. Neutral (7.0)A reading of 7.0 on the pH scale is the ideal level for drinking water. However, international water guidelines stipulate that water is considered safe for consumption with readings between 6.5 and 8.5.Alkaline (8.0 – 14.0)Water that is alkaline will produce a reading of between 8.0 and 14.0 on the pH scale. Several claims have been made about the beneficial health properties of drinking alkaline water.Specification: Package Weight One Package Weight 0.08kgs / 0.19lb One Package Size 10cm * 8cm * 1cm / 3.94inch * 3.15inch * 0.39inch Qty per Carton 179 Carton Weight 15.00kgs / 33.07lb Carton Size 56cm * 45cm * 5cm / 22.05inch * 17.72inch * 1.97inch Loading Container 20GP: 2116 cartons * 179 pcs = 378764 pcs40HQ: 4913 cartons * 179 pcs = 879427 pcs

1. Power adapter: Input 100-240V AC / Output 12V 1A DC2. Purpose: test spark plug performance and ignition strength3. Application range: 12V gasoline engine automotive spark plugs4. The dual-hole automotive spark plug tester has two test holes, which can test two spark plugs at the same time. If you suspect that any spark plug is not working properly, you can do a comparative test to make an accurate judgment5. Test principle: In the automotive ignition system, the high-voltage ignition coil generates a high voltage (more than 10,000 volts), and the spark plug leads it to form a high-voltage ignition coil into the cylinder engine. The spark between the spark plug electrodes ignites the mixture. The detector can distinguish good spark plugs from bad spark plugs according to the intensity of the spark6. Turn the key switch clockwise to turn on the tester, and the indicator light is green7. Close the protective cover, insert the adapter into the side socket, and connect the tester to the power supply to turn it on8. Turn the switch clockwise to adjust the operating frequency between 1000rpm and 6000rpm/min. The higher the frequency setting, the stronger the spark.9. Dimensions: 145x85x60mm10. Weight: 354gInstructions for use of the automotive spark plug tester:1. Turn off the power before placing the spark plug2. The spark plug tester is a high-voltage detector.
