How to choose the
best parallel rulers
What is the Purpose Of A Parallel Rulers?
Parallel ruler is a tool which is used to measure distances between two points. It has been around since ancient times. There are many types of parallel rulers available in market today. Some of these tools are very useful while others are not. Let us discuss few features of parallel rulers.
Features of a Parralel Ruler
The most common type of parallel ruler is called "standard" ruler. Standard ruler consists of two straight edges which are perpendicular to each other. One edge is marked with numbers 1 to 10. Another edge is marked with units of measurement (inches, feet etc.).
How To Use A Standard Ruler
To use standard ruler, you must align both ends of the ruler with the point where you wish to start measuring. Then, slide the ruler along the line. As soon as the end of the ruler touches the object being measured, stop sliding the ruler. Now, read the number written on the ruler. Repeat the same process for the second side of the ruler.
Types of Parallel Rulers Available
There are different types of parallel rulers available in market. Each type of ruler has its own advantages and disadvantages. Here we list few types of parallel rulers available in market.
Tape Measurer - Tape measures are widely used in construction industry. It is easy to carry and store. However, tape measures cannot be used to measure angles. So, if you are planning to build a house or a building, you should go for a digital level.
This is another popular type of parallel ruler. Digital levels are designed to measure horizontal and vertical lines. Most of the modern digital levels are equipped with LCD display screen. This enables user to view angle measurements directly on the screen.
These are simple devices which consist of a long pole and a weight attached to the bottom of the pole. Plumb bobs are commonly used in construction industry. They are extremely handy and easy to use. But plumb bob is not suitable for measuring angles. For measuring angles, you should opt for a digital level.
Level gauges are small handheld instruments which enable users to measure heights. Level gauge is ideal for measuring height of objects. It is lightweight and portable. Level gauges are available in three forms; bubble, spirit and liquid
The Importance of Purchasing a Quality Parallel Rulers
Parallel ruler: A tool used to measure distances between two points along a straight line. Most commonly used to determine the length of lines, angles, and circles. Used to draw perfect squares, rectangles, triangles, etc.
There are many types of rulers available today. Some are designed specifically for measuring lengths while others are designed to be used for drawing purposes. There are several different types of rulers including those which are adjustable, fixed, folding, telescopic, and retractable. Each type has its own advantages and disadvantages. For example, the adjustable ruler is easy to set up and adjust, however, it does not allow for accurate measurements due to the fact that it must be adjusted each time a measurement is taken. Fixed rulers are very useful since they are already set up for specific measurements. However, these rulers cannot be adjusted once set. Telescoping rulers are convenient because they fold into themselves making storage easier. Retractable rulers are ideal for students who travel frequently. They are small enough to carry around and large enough to hold multiple pieces of paper. But there are drawbacks to using retractable rulers. First, they are difficult to store. Second, they require constant readjustment during use. Third, they are not suitable for long term use. Lastly, they are prone to breakage.
Types of Rulers
Rulers can be classified according to their shape, size, material, and function. Shape refers to the overall design of the ruler. Size refers to the width and height dimensions of the ruler. Material refers to the composition of the ruler. Function refers to the way the ruler is used. Examples include:
Adjustable - Allows for precise measurements. Can be adjusted to accommodate varying distance requirements. Adjustments can be made manually or automatically.
Fixed - Cannot be adjusted. Only measures exact distances.
Folding - Folded flat for ease of transport and storage.
Telescopic - Extendible for greater accuracy.
Retractable - Small enough to be carried around yet large enough to hold multiple sheets of paper.
Each type of ruler has its own unique benefits and limitations. Below we list the pros and cons associated with each type of ruler. Please note that the following information is based on our experience and research. We hope that this information will assist you in selecting the right ruler
Features To Look For When Buying A Parallel Rulers
1) Size -
The size of the ruler is very important. There are many different types of rulers available in the market today. Some are designed specifically for measuring small objects while others are meant for large scale measurements. Make sure you check the dimensions of the ruler before purchasing it. Most rulers measure between 1 inch (2.5cm) and 12 inches (30 cm). However, there are some larger ones which go up to 24 inches (60 cm).
2) Material -
There are two main materials used to manufacture rulers; plastic and metal. Plastic rulers are cheaper than metal ones. Metal rulers are durable and long lasting. But they are heavier than plastic ones. So, depending on your needs, you can opt for either type of ruler.
3) Weight -
Rulers vary in weight. Some weigh around 0.4 ounces (11 grams), while others weigh 2 pounds (0.9 kg). Heavyweight rulers are good for heavy duty jobs. Lightweight rulers are ideal for light duty jobs. You can always adjust the weight according to your requirements.
4) Durability -
Durability is another factor to take into consideration. Rulers are generally manufactured using high quality material. Therefore, they last longer than cheap products. Cheap rulers are prone to breakage due to poor manufacturing techniques. Always ensure that the product you are going to buy has been tested and certified by independent testing agencies. Such tests include impact resistance, drop test, bending strength etc.
5) Accuracy -
Accuracy is another key aspect to be considered. All rulers must meet certain accuracy standards. Otherwise, they cannot be sold legally. Check the manufacturer’s website to see whether the product meets these standards. If not, contact the company directly to ask about its certification status.
Buying a ruler is easy. Just follow the tips mentioned above and you will end up with a perfect tool for your next project. Remember, a ruler is a versatile tool that comes in handy in almost every field. Whether you are a student, engineer, architect, carpenter, painter, designer, craftsman, mechanic, plumber, electrician, landscaper, gardener, photographer, musician, chef, cook, artist, sculpt
Different Types of Parallel Rulers
Parallel ruler: A type of measuring tool which has two straight edges that meet at right angles. Used for drawing lines perpendicular to each other.
Tape measure: A tape measure consists of a flexible metal strip attached to a handle. Tape measures are commonly used for marking distances along walls, floors, ceilings, etc.
Ruler: A long thin piece of material (usually plastic) marked into equal divisions called "tenths" or "minutes". Used for measuring lengths, widths, heights, areas, volumes, etc.
Level: A level is a special instrument designed to be placed on a flat horizontal surface. Levels are useful for determining verticality and horizontality.
