Manufacturer: LYNXTECH Brand: LYNXTECH Color: TDS-4

Product Description How Pure is Your Water? A TDS meter (aka ppm pen, nutrient tester, tds stick) is an inexpensive and convenient digital tool to instantly check your overall water quality. TDS = Total Dissolved Solids, which is any salt, metal or mineral in the water. With the push of a button, the TDS-4 can tell you your overall water purity level,which will be displayed on the screen in ppm (parts per million). The lower the TDS level, the purer the water, with 0 ppm being pure H2O. The TDS-4 is great for checking your tap water quality, or knowing when to change a filter. (The meter does not test for biological contaminants.) The TDS-4 is a great tool for drinking water, water filtration and purification,hydroponics (test your nutrients), colloidal silver, aquariums, RO/DI systems, pools and spas, and more. From the Manufacturer TDS Tester with Advanced Microprocessor Technology.

Are you a "Supertaster?!" Materials Included: Premium Storage Case 100 Strips containing Phenylthiourea (PTC) 100 Strips containing Sodium Benzoate 100 Strips containing Thiourea 100 Strips containing NO chemical (Control) Key Vocabulary: Genotype: the specific genes found in DNA. Phenotype: the physical expression of genes (examples: eye color; tasting ability). Heredity: the passing of genetic information from parent to offspring. Punnett Square: a method for determining the qualitative chances of offspring inheriting certain genes from their parents. Just as humans have different levels of acuity in the senses of smell and sight, they also have differences in their ability to taste. Approximately 25% of Americans are considered "supertasters" and, of this subset, people have varying levels of "supertasting" ability. "Supertasters" are people who have the ability to taste the substance Phenylthiourea (PTC). Some people cannot taste this substance at all and others taste it quite distinctly. Whether ...
