Water is vital to human life. Drinking water, swimming pool water, SPA water, aquarium water, fish pond water, is related to the quality of everyone's life, every day to contact, then how to ensure the quality of water? Water quality test strips, of course. These convenient and easy-to-use strips quickly and accurately test for a range of contaminants and keep you and your family safe.

The main advantages of double-effect external circulation evaporator equipment
The external circulation evaporator is a set of equipment for evaporating and extracting materials. The double-effect external circulation evaporator is a set of equipment that becomes more energy-efficient and efficient, and the external circulation evaporator can be used for industrial wastewater treatment, urban sewage treatment and the like. Waste water is also a resource.
The main advantages of the double-effect external circulation evaporator equipment are:
1. Contact material: All materials in contact with the material are made of 304 material.
2. Low temperature concentration, the whole evaporation process of the equipment is under vacuum, which reduces the evaporation temperature of the material, so that the material is not easy to scale in the heating and evaporation process, and can meet the requirements of heat sensitive food, traditional Chinese medicine, western medicine and heat sensitive material concentration.
3. Latent heat utilization of condensed water: The condensed water produced by the first-effect evaporator flows into the second-effect evaporator, and the sensible heat of the condensed water is utilized. The condensed water produced by the last one and the second effect is discharged into the condensate water pump through the condenser.
4. Composition of the equipment: This equipment consists of one and two effect evaporators, one and two effect separators, condenser, vacuum pump, electric control box and all pipelines and valves.
5. Energy saving and consumption reduction, the secondary steam separated by the first-effect separator enters the second-effect heater for heating, and the secondary steam separated by the second-effect separator enters the condenser for condensation, so the heat is reused, which greatly saves steam. Consumption, while also saving cooling water circulation.
6. The heater and the evaporator are all provided with an insulation layer, the insulation is foamed with polyurethane, and the outer surface is matt treated. During the whole process of heating and evaporation, it is completed in the airtight state, and does not touch the outside world at all, reaching the GMP medical standard.
7. Concentration ratio is large, which simplifies the process, shortens the concentration time, reduces pollution, concentrates and does not run the material, can improve the collection of the paste, and guarantees the product quality.
8. Improve working conditions, normal operation, stable production, convenient cleaning, no heavy physical labor, one person can operate, the concentrated site has no running, taking, dripping, leaking, improving the working environment, the site is clean and tidy, and is conducive to the realization of civilized production.
TEST PROCEDURE
Immerse the strip for 2 seconds and then remove the strip.
Do not shake excess water off, and then hold the strip horizontally for 20 seconds.
Compare against the color chart and read immediately within 30 seconds to get accurate result.
IMPORTANT TO KNOW
1.Test for 30 seconds
When using the Water Test strip, your results are complete (ready to compare) after dipping the
test strip. Upon completion, make sure to compare your results immediately. The strip is no
longer valid outside of the 30 second testing period Discard the test strip after 60 seconds as
any further color change will be meaningless.
2.Prevent altered results
Here`s what you can do to prevent decreased shelf life of the strip and altered results
Do Store in a cool dry place away from direct sunlight.
Do read the instructions carefully before use.
Do Avoid touching or polluting test areas of the strip.
Do not place wet fingers in the bottle.
Do Keep the cap on tight between use.
Do not remove the desiccant pouch.
3.Primary and Secondary water Regulations
The EPA sets legal limits on over 90 contaminants in water test strip. There are two categories,
primary and secondary. Primary contaminants are substances that can be toxic in small amounts
On the other hand, secondary contaminants are less toxic species and would include cosmetic
issues (color, taste, and odor) of water. These strips test for the most commonly found primary
contaminants lead, fluoride, copper, chlorine, nitrite, nitrate) as well as the most commonly found
secondary contaminants(Copper, Iron, Sulfate, Zinc, Manganese, Fluoride, Chloride, and pH)
