What is Gaussian?Gauss is a unit of magnetic field. 5000 Gauss represents your magnet with a maximum magnetic field of 5,000 Gauss.2. How much can Gauss be achieved by magnetism?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.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.3. How many Gaussian magnets are the largest?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.In general, the Gaussian surface of the magnet is such that it is inversely proportional to the area and is proportional to the thickness.4. How do you know how big a Gaussian magnet is?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.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

Alcohol Refractometer Alcoholometer 0~80% ATC Handheld Alcohol TesterThis Alcohol refractometer is designed for the measurement of distilled beverages (ethanol with water) like whiskey, brandy, fruit brandy, slivovitz, vodka, gin, tequila, Chinese alcohol, etc.It has a scale in the range of 0 - 80 % (VOL - alcohol volume percent).With Built-in ATC (Automatic Temperature Compensation) from 10~30 degree Celsius.Soft Rubber eyepiece for comfortable viewingEquipped with scale measurement which provides direct readingAdjustable manual focusingUse ambient light only which means battery or power source is not requiredEasy and very convenient to use. Place a few drops of the liquid on the optical part of the refractometer, cover the prism (the liquid will spread more easily over the prism), look through the eyepiece against the light (focus, if necessary) and you will be able to read the result value on the scale.Measuring Range 0-80% v/v(VOL - alcohol volume percent).Widely used for scientific research, food producing, alcohol retailer, etc.Before you use a refractometer, it needs to be calibrated. Most refractometers are calibrated by using a sample of distilled water. Add a few drops of distilled water to the clear sample plate. Close the daylight plate and allow the water to spread across the sample plate. Make sure there are no bubbles. Refractometers are temperature sensitive, so allow the hot sample to cool and reach room temperature not exeeding 10 - 30 degrees Celsius.Hold the refractometer up to natural light and take a reading. Most refractometers have a calibration knob or screw that will let you adjust the zero setting. What you want to do now is adjust the refractometer with the included screwdriver so it reads zero with distilled water in it. (A sample of pure water will have a specific gravity of approximately 0.998 at 20 degrees Celsius.) This may take a few tries.Thereafter, you could also use another liquid with known specific gravity (weight per liter) typically these sell as refractometer calibration liquid (not included)

TVOC = Total Volatile Organic Compounds.Should be below 0.3mg/m3 or 300ug/m3 to be safe but even up to 0.5mg/m3 would be acceptable. A typical house indoors will display no more than 0.15mg/m3 TVOCSources of VOCspaints, paint strippers and other solvents.wood preservatives.aerosol sprays.cleansers and disinfectants.moth repellents and air fresheners.stored fuels and automotive products.vinegar.While candles, barbecues and gas stoves all make for a nice home, they also increase the presence of butanal, one of the most common volatile organic chemicals also found in cigarettes.dry-cleaned clothing.alcohol in santisers ie isopropanol is a common solvent for home and professional use. It’s often used as a disinfecting agent, and it also evaporates quickly, making it easy for large amounts to build up in the home. Make sure to have proper ventilation to maintain air quality.Formaldehyde is very common and used as a preservative.Nail polish contains harsh solvents such as acetone which is also used in furniture polish and wallpaper.Benzene is found in paint, glue, carpeting, etc. Carbon Disulfide is found in chlorinated water.Dichlorobenzene found in mothballs and deodorizers.Terpenes found in fragrant products such as soap or laundry detergents.----------------------pm2.5 pm10 pm1.0Particulate Matter (PM) BasicsMost studies indicate PM2.5 at or below 12 μg/m3 is considered healthy with little to no risk from exposure. If the level goes to or above 35 μg/m3 during a 24-hour period, the air is considered unhealthy and can cause issues for people with existing breathing issues such as asthma.Example sizes: dust:9umred blood cells: 7-8umTechnically, there isn't a safe level of PM10, as any amount of particulate matter in your air isn't a good thing. Keeping your exposure to PM10 concentrations below 54.0 µg/m³ is the best way to prevent any short or long-term health effects from developing.Less than 40 is considered Good.80-120 is fair with 120-300 very poor and more than 300 extremely poor.PM1 are extremely fine particulates with a diameter of fewer than 1 microns and may potentially be more harmful to human health.Examples: dust, combustion particles, bacteria and viruses.-------------O3Ozone at ground level – not to be confused with the ozone layer in the upper atmosphere – is one of the major constituents of photochemical smog. It is formed by the reaction with sunlight (photochemical reaction) of pollutants such as nitrogen oxides from vehicle and industry emissions and volatile organic compounds (VOCs) emitted by vehicles, solvents and industry. As a result, the highest levels of ozone pollution occur during periods of sunny weather.Recommended exposure limit for ozone is 0.2mg/m3 or 0.075ppm. Ozone levels of 5ppm or higher are considered immediately dangerous to life or health.

High Precision ph Meter with batteries, buffer powders and hard box. Low energy Consumption. Auto Calibration. Auto TEMP Compensation. Build-in High-Precision Chip.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.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. 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.
