Low-temperature 1-color Pyrometer
This classification includes one color infrared pyrometers measuring range is 250℃-2200℃. The one color pyrometers currently on market are mostly narrow-band pyrometers. Its principle of temperature measurement is to determine the temperature by detecting the radiant energy that occurs in a narrow wavelength range of an object. The temperature a pyrometer measured is the average temperature in an area, and the measuring result is affected by emissivity, lens contamination and background radiation.
To use 1-color pyrometer mode, the measured area of the object should be large (it can fully fill the target field of view) , object surface should be relatively flat (not curved), measurement direction should less than 30 degrees, and the physical and chemical state of the measured object surface should be stable (not in the process of oxidation, gasification or liquefaction) , the optical channel should with less dust and without blocking and attenuation.

A common misconception is that tricycles are only for kids, but that's far from the truth. In fact, the first tricycle was actually designed for adults, and today, people of all ages enjoy riding them around the world. Tricycles offer a unique blend of stability, comfort, and versatility that makes them appealing to a wide range of riders.
An upright tricycle, also known as an upright trike, is a three-wheeled vehicle that can be human-powered, motor-assisted, or even gravity-powered. These bikes are typically lower to the ground than traditional bicycles and feature a step-through frame for easier mounting and dismounting. While they’re great for short trips and daily commutes, they aren’t the best option for intense cardio workouts due to their heavier build and less efficient pedaling. However, their added stability and practicality make them ideal for shopping, leisure rides, and even small deliveries.
Tricycles have been used by various groups throughout history. Initially, they were popular among women who felt unsafe on high-wheelers (like the Penny Farthing), especially because of their long dresses. Today, they are enjoyed by many, including those with mobility issues, seniors, and anyone looking for a more comfortable and stable ride. Their ease of use, upright seating position, and enhanced safety features make them a great alternative to traditional bicycles.
The history of tricycles dates back to 1655 when German watchmaker Stephan Farffier created one of the earliest designs. Later, in 1789, French inventors developed a pedal-powered version called the tricycle. James Starley, a British inventor, played a significant role in popularizing tricycles in the 1800s. Over time, different types of tricycles emerged, such as rickshaws, freight trikes, and children’s models. Although tricycles fell out of favor with the rise of automobiles, they have seen a resurgence in recent years, especially among adults seeking a reliable and accessible mode of transport.
There are several types of upright tricycles, each suited for different needs. Conventional uprights come in delta or tadpole configurations, offering varying levels of stability. Rickshaws are used for passenger transport, while freight trikes are built for carrying cargo. Children's tricycles are smaller and simpler, often featuring front-wheel drive. Drift tricycles are designed for downhill fun, and electric tricycles provide extra power for easier riding.
When choosing a tricycle, consider key features like brakes, gears, and cargo capacity. Coaster brakes, hand brakes, and disc brakes are common options, each with its own advantages. A single-speed model may be sufficient for flat terrain, but geared models are better for hills or heavy loads. Cargo carriers vary depending on the type of tricycle, so it's important to choose one that suits your needs.
Essential accessories include a helmet, lock, bell, lights, and water bottle holders. These items enhance safety and convenience. Mirrors are useful for city riding, and phone mounts can help with navigation. Additional storage options can be added if needed.
Popular brands like Schwinn, Mantis, Vanell, and Barbella offer a range of models tailored to different preferences. Each has its strengths and weaknesses, so it's worth researching which one fits your lifestyle best.
Finally, protecting your investment is crucial. Always secure your tricycle when not in use and consider insurance options like Velosurance to cover theft, damage, or loss. With the right care and equipment, a tricycle can be a reliable and enjoyable way to get around.
