Choosing a scale glider depends on the operator’s skill level, materials, components, ease of handling, flight types, and costs. Scale gliders are useful for beginners to learn before attempting radio-controlled powered aircraft flight. They are made of wood, plastic, fiberglass, polymer foams, carbon, and composites, with various wing configurations. Scale model gliders come in different […]
Limescale buildup in pipes decreases flow volume, increases pressure, and makes water-based machines work harder. Pipe scale is caused by minerals in flowing liquid and can cause flow variations, increase electricity usage, and shorten the life of connected devices. It also affects the taste of drinking water and can cause bacteria buildup. Pipe scale in […]
Mill scale is a by-product of the steel rolling process that forms a thin layer of oxidized metals. It can protect steel from corrosion but must be removed before painting or other treatments. Methods include chemical removal or weathering. Steel quality can vary based on production processes and materials used. Mill scale is a very […]
Hydraulic scales use compressed hydraulic fluid to measure the mass of a test weight, with load cells and a display translating the pressure into a visible indication. They range from simple overhead scales to large weighbridge models and are reliable and accurate, making them popular for high-traffic applications. A hydraulic scale is a measuring device […]
A vernier balance is a measuring tool with a second scale next to the primary scale, invented by Pierre Vernier in 1631. It improves accuracy by aligning the vernier mark with the primary scale. It is used in micrometers, calipers, weighing devices, and other tools for precision measurement. Vernier scales can be flat or rotary, […]
A digital kitchen scale is more accurate than mechanical or spring scales and can measure in both avoirdupois and metric units. It also has a tare function and is easy to clean, but some models have a quick automatic shut-off. A digital kitchen scale measures the weight of foods and ingredients. It can be used […]
A forklift scale allows for the weighing of objects lifted by the forklift, typically using sensors in the forks or hydraulic system. It can process weights in kilograms or pounds and may require additional battery power. Forklift scales are used in transportation and manufacturing companies to ensure legal weight limits and prevent lifting heavier objects […]
Body composition scales offer more information than traditional scales, measuring body fat through bioelectrical impedance analysis. They provide more accurate health information than BMI charts, but require consistency and hydration for accurate readings. They cost around $100 USD. While most scales simply measure weight, a body composition scale offers much more information. The thing is, […]
A refrigerant scale measures the weight of refrigerant added to or removed from an air conditioning system. Proper maintenance is important for system longevity and user comfort. Technicians use the scale to find leaks and perform routine maintenance. Scales vary in weight capacity, accuracy, and durability. Some models can be programmed to automatically add or […]
The Bristol stool scale categorizes stool samples into seven types, ranging from constipation to diarrhea. It was developed to estimate fecal transit time but is now used to evaluate treatments for bowel diseases. The scale is useful for clinicians and patients to monitor bowel habits, but medical advice should be sought for significant or persistent […]
The Abbreviated Injury Scale is a standardized scoring system used in injury assessment that can help make decisions about patient care and be used in injury survival studies. It was developed by the Association for the Advancement of Automotive Medicine and assigns a numerical score between one and six to evaluate injuries. The score can […]
The Brief Psychiatric Rating Scale (BPRS) is a test used by mental health professionals to evaluate psychiatric symptoms, often with patients who have severe psychological impairment. It has 18-24 sections with a rating scale of 1-7, and is used for diagnosis and to assess patient progress. Observation by the healthcare professional is critical, as well […]
The Face, Legs, Activity, Cry and Consolability (FLACC) scale is used by medical professionals to determine pain levels in young or uncommunicative patients. The scale assigns a score of zero, one, or two for each category, with the sum being the patient’s pain score. Other pain scales include the Wong-Baker Faces pain graph and the […]
The NIH Stroke Scale is a clinical rating scale used to assess the likelihood of an individual having a stroke based on their clinical examination. It evaluates motor function, cognition, sensory function, level of consciousness, vision, and speaking ability, and patients receive a score ranging from zero to 30. A low score suggests a good […]
A digital bathroom scale displays weight as a digital numeric readout and can estimate body fat percentage and body water. It is usually made of glass, metal, or plastic and can be found at home supply stores or online. A digital bathroom scale is a device that allows the user to determine their current weight […]
The Kinsey scale represents the diversity of human sexual orientation, allowing for fluidity and flexibility. It ranges from one to six, with an additional category for asexuals. Kinsey’s research showed that sexual orientation often changes throughout life. The scale has helped to break down societal conceptions of homosexuality and dispel the notion that people cling […]
The Glasgow Coma Scale (GCS) is a tool used to assess a person’s level of consciousness, developed in the 1970s at the University of Glasgow. It assesses eye response, movement, and verbal response, with scores ranging from 3 (deep unconsciousness) to 15 (fully awake and aware). The Pediatric Coma Scale is used for infants. Injuries […]
The Modified Rankin Scale (MRS) evaluates stroke patients’ disability levels with scores ranging from zero to six. Low scores indicate high functioning, while high scores indicate severe disability or death. The rubric is used for follow-up, prognostic predictions, and clinical trials. The Modified Rankin Scale (MRS) is a rubric used to evaluate stroke patients. It […]
The Glasgow Outcome Scale is used to assess a patient’s recovery from a traumatic brain injury or stroke, with scores ranging from one to five indicating the level of disability. It is not used for treatment planning, but as a shorthand reference for physicians and organizations. The related Glasgow Coma Scale is used to assess […]
Temperature is measured by the movement of molecules, with common scales including Fahrenheit and Celsius. Absolute scales, based on zero as a theoretical value, were created by Lord Kelvin and William Rankine. Properties of gases and materials at low temperatures are important for analysis and gas separation. The triple point, where a material can exist […]
