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.

TC100 Coating Thickness Gauge Ultra-precise 0.1micron / 0-1300 Fe and NF with calibration plates
Automatically identifies iron or aluminum
substrate, the screen quickly displays the substrate material, Fe stands
for ferromagnetic substrate, and NF stands for non-ferromagnetic
materials, such as aluminum, aluminum alloy, copper, etc.
Whether it is ordinary paint or metallic paint, the paint thickness can be accurately measured.
The minimum resolution is 0.1um, and the resolution above 100um is 1um. Range: 0.1 ~ 1300um.
Measures the thickness of galvanized layer, nickel plated layer, gold plated layer, metal oxide layer, anodized layer, etc.
Cannot measure the thickness of paint on plastic surfaces.
Coins were metered on the smooth section of the coin as the instrument
will give a faux reading of any uneven impression on the coin.

These molecules help neutralize oxygen free radicals that contribute to disease development, inflammation, and aging.In our body, Oxygen molecules split into single atoms with unpaired electrons, causing the atom to become unstable; also known as free radicals. Electrons like to be in pairs, so these free radicals, scavenge the body to seek out other electrons so they can become a pair. This causes damage to cells, proteins and DNA leading to inflammation, illnesses and aging.Anti-oxidants such as vitamin E and C can contain the free radicals to a certain extent. Not that you should not exercise as it's beneficial for one's wellbeing but too much exercise with poor nutrition also produces unchecked free radicals as does excess anti-oxidants which becomes pro oxidative contributing to increased oxidative stress which in turn perpetuates the vicious cycle of the formation of free radicals.Another manner in which one can counteract the 'bad' oxygen atoms in our body is to expose them to free Hydrogen molecules in the form of hydrogen rich water.DO NOT USE CHLORINATED TAP WATER TO PRODUCE YOUR HYDROGENATED WATERWORKS BEST WITH ANY CHLORINE FREE SPRING WATER OR PURIFIED WATERMaterial: Borosilicate GlassPower Supply: DC 5V 1A (Please note: do not use Samsung chargers at 9.6Volts)Maximum Power:2W (charged via USB port)Maximum Capacity:500MLNet Weight: 750gHydrogen Concentration Range:600-1000 PPbWater Temperature Requirement:1-40 CentigradeEverything in moderation.

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.
