Because experimentation is an essential and complementary element of gaining knowledge and information in the classroom or laboratory setting, you have to be equipped with the proper tools and equipment to carry out the different scientific processes needed to establish fact from theory. This is where the best mechanical balances prove to be indispensable for measuring masses and weights. What segregates the top quality mechanical balances on the market from the competition?
Reliable construction for a variety of purposes
The laboratory and classroom setting can be demanding on the type of equipment used on a daily basis. A mechanical balance can be used for chemistry and physics experiments, medical hygiene weighing, foodstuff, analytical weighing in chemical works, textiles, agriculture, mines, electronics, high school science labs, scientific research institutions, colleges and universities and plenty more. This means the gear you decide to buy from the best mechanical balance reviews should boast a high level of durability to withstand the rigors of daily use.
The components themselves should be of high quality and the finest materials. Metal beams and bases ensure durability. Quality models are equipped with Aluminum pressure cast bases and beams. A stainless steel pan, tray or platform is resistant to rust and chipping and is easy to clean. The triple beam should be made of high quality aluminum alloy for years of use. Some models come with an aluminum housing to ensure durability and strength. The best ones have earned certification for compliance with ISO 9001:2000 standards.
Easy and quick use
It will be easy for users to know how to read a mechanical balance if the instrument itself is engineered to facilitate the entire process. Most models feature a single weighing unit and application mode so you won’t have to be overwhelmed with complicated procedures for finding the correct weight and mass of objects. The pointer and angled beams should be easy to read to help reduce operator errors, with steel knife edges if possible. Quick zeroing is facilitated with special floating agate bearings and a counter balancing knob that ensures the beam balance stays in position. A spring-loaded zero-adjust compensator enables fine modifications. Dial operations provide convenience and speed.
Reading is also more effortless at the center if the mechanical balance has notched and tiered beams. Some models feature a tripod assembly that raises the device several inches off the countertop surface to enable effortless density determination. Oscillation can be slowed down with magnetic damping, which provides fast and accurate readings every time. Dual pointers allow easy dual side viewing of results. You want the platform to be removable for easy placement of samples and to facilitate cleanups. The weighing pans should be large and washable. A tare function enables repeatable, fast weighing. Some models come with a hanging pan balance and a stainless steel pan with pour spout for easy unloading and viewing of samples. Others have built-in storage for the supplied counterweights.
How does a mechanical balance work? A large mother beam is supported by a fulcrum, with one side outfitted with a pan on which the object to be weighed is placed. The other side carries a primary beam split into three parallel secondary beams, with each one supporting a single weight of its own. Instead of adding additional weights when measuring the weight of an object, you simply slide the weights along the respective beams to increase their lever arm. Just like a seesaw, the one with the heavier weight sits closer to the fulcrum section to decrease their lever arm. To make this possible in a mechanical balance, the zero adjustment should be easy to use for repeatability and accuracy. Most mechanical balances feature a tare capacity for fast repetitive weighing.
With magnetic damping, the pointer is brought to rest with minimum oscillation or swings. Some devices come with pre-calibrated weights to extend their weighing range. With positive poise positioning, repeatable results can be obtained. Level adjustments are eliminated if the balance works with special floating bearing principle and beam design. Zero adjustments are made easier with a zero adjust knob at the end of the primary beam.
