Electronic balance

An electronic balance is a laboratory instrument used to accurately measure the mass of an object. It consists of a weighing pan, a sensor, and an electronic display. The sensor measures the force exerted by the object on the weighing pan, and this data is then converted into a digital display of the object's mass. Electronic balances are commonly used in scientific research, pharmaceuticals, and industrial settings where precise measurements are required. They offer greater accuracy and precision compared to traditional mechanical balances, and can weigh objects to the nearest 0.1 milligram or even finer.

Decade resistance box

The function of a decade resistance box, also known as a resistance substitution box, is to provide a convenient way to adjust and measure electrical resistance in circuits. It consists of multiple resistors arranged in a switchable array, allowing the user to select different resistance values and combine them in series or parallel configurations. This allows for precise control of the resistance in a circuit for testing, calibration, and troubleshooting purposes. Decade resistance boxes are commonly used in electronics, telecommunications, and other industries where accurate measurement and control of resistance is important.

Electric hot air drying oven

An electric hot air drying oven is a device used for drying materials or samples at high temperatures using forced hot air circulation. It is commonly used in industries such as pharmaceuticals, food processing, chemical processing, and research laboratories. The oven is equipped with a fan that circulates hot air inside the chamber, allowing for even drying and preventing moisture buildup. It is an efficient and reliable way to remove moisture or solvents from samples or materials, and can also be used for sterilization and curing processes.
