High Precision pH Meter with batteries, buffer powders and hard box<br /> Low energy Consumption. Auto Calibration. Auto TEMP Compensation. Build-in High-Precision Chip.<br /> <br /> Notice: 1.This meter can test any solution, including strong acids, alkali and viscous samples like shampoo. But it cannot test solids like soil and fabric directly, they need to be mixed with water, beforehand.<br /> 2. Moreover, strong acid and alkali will greatly affect the service life of the electrode. This is inevitable even if you buy a much expensive acidity meter. <br /> 3.The glass bulb sensor of the electrode is fragile. Do not touch the bulb sensor by hard tools or fingers, and handle with care when cleaning.

PH Tester Chlorine Level Meter Grey White Water Quality Tester<br /> Plastic Shell Swimming Pool Spa Water Quality Monitor<br /> <br /> Description:<br /> This water quality tester is designed to test pH and chlorine level for swimming pools and spas. It is easy to operate, no more chemicals need. Large screen quickly shows the test result with high precision. Light weight and compact, easy to carry.<br /> <br /> Specifications:<br /> Material: Plastic + Metal<br /> Color: Gray White<br /> Size: approx. 18 x 11.6 x 3.1cm / 7.1" x 4.6" x 1.2"<br /> Power Supply: 1 x 1.5V AA Batteries(not included)<br /> Recommended chlorine level for pools and spas: 1.2 ~ 1.7ppm<br /> Recommended pH level for pools and spas: 7.2 ~ 7.8pH<br /> Package Weight: 220g<br /> <br /> Attention:<br /> 1. Please don't immerse the probe in any liquid other than pool or spa water.<br /> 2. Please rotate the switch to close position when not in use.<br /> 3. Please store the tester in cool and dry place.<br /> <br /> Usage:<br /> Before you use this tester for the first time, you must adjust it to match your swimming pool or spa water with the following sequence:<br /> 1. Test your pool or spa water using a conventional liquid test kit<br /> 2. Record the chlorine reading level as you will need.<br /> 3. No adjustment is required for pH.<br /> <br /> How to find adjustment point for chlorine testing:<br /> 1. Insert 1pc AA 1.5V battery in the compartment in the handle.<br /> 2. Hold the tester in one hand and the probe in the other.<br /> 3. Insert the cleaned metal probes into the water up to the black band.<br /> 4. Stir the water slightly with the probe.<br /> 5. With the probe still in the water, turn the wheel on the face of the tester all the way to the left towards "CL". Slowly turn the wheel back to the right until the needle matches the chlorine level you recorded with the convention liquid tester(e.g.: 1.5ppm)<br /> 6. Remove probes from the water without touching the wheel. Indicator will move all the way to the right and stop on a letter between A and E. This letter is your "adjustment point".<br /> Note: Any time you use this tester to test the chlorine level, you must adjust it to the "adjustment point" before testing. <br /> Testing Chlorine Level:<br /> Recommended chlorine level for pools and spas: 1.2 ~ 1.7ppm<br /> 1. Position the needle to your "adjustment point".<br /> 2. Holding the tester in one hand and the probes in the other, insert the probes into the water up to the black band. Wait until the needle rests for a better chlorine reading.<br /> 3. Leave the probes in the water.<br /> <br /> Test pH Level:<br /> Recommended pH level for pools and spas: 7.2 ~ 7.8<br /> 1. With the probes still in the water, turn the wheel all the way to "pH" until it clicks(battery must off for pH reading).<br /> 2. Wait until the needle rests on the pH reading.<br /> 3. Gently dry probes and insert into the holder on the side of the tester for storage.

What is Gaussian?<br /> Gauss is a unit of magnetic field. 5000 Gauss represents your magnet with a maximum magnetic field of 5,000 Gauss.<br /> <br /> 2. How much can Gauss be achieved by magnetism?<br /> This question is very general, and we don’t know how to answer it and make you satisfied. Because the magnet’s magnetic level is related to many factors, such as the grade of magnets, the specifications of the magnet, the thickness and so on.<br /> <br /> But we have collected some common specifications of magnet Gauss for your reference Such as 10 * 4 N35 Gaussian material can reach about 3000-3200 Gauss, 10 * 5 to about 3400-3600 Gauss. The surface magnetic field of a single NdFeB magnet is 3000-5000G, ferrite 300-800G, samarium cobalt, and AlNiCo 2000G. Neodymium iron boron should be considered as a very high permanent magnet, but it is difficult to reach 5000 or more.<br /> <br /> 3. How many Gaussian magnets are the largest?<br /> N35, N38 is probably up to 2000GS. If the size is bigger, N35 can reach 3500GS at most, N38 can reach 3800GS. If anyone tells you that he/she has a magnet above 10,000 gausses, you must marry them first, because they have new technology.<br /> In general, the Gaussian surface of the magnet is such that it is inversely proportional to the area and is proportional to the thickness.<br /> <br /> 4. How do you know how big a Gaussian magnet is?<br /> We usually use a Gauss meter to measure the Gaussian magnet surface. However, the Gaussian values measured at different positions on the surface of the magnet are different, and the Gaussmeters have different measured data, and the error is relatively large.<br /> <br /> 5. What is the difference between a Gaussian magnet and a magnetic flux? Both Gaussian and flux measurements are made to determine the performance of the magnet. The reproducibility of magnetic flux is better than Gaussian, more stable, and the error is not too big. Note: Gaussian (Gs) is the unit of measure for magnetic field lines. 1T=10000 Gs </p>
