Let’s Dive into Bel-Art Plastic Calipers, SCIENCEWARE 134160001 Caliper With Dial
The Bel-Art Plastic Calipers, SCIENCEWARE 134160001 Caliper With Dial are designed for precision measurement in laboratory and industrial settings where metal calipers could cause scratching, corrosion, or contamination. Bel-Art, a division of SCIENCEWARE, is known for producing reliable and affordable lab equipment. This particular caliper boasts a dial indicator for easy and accurate readings, making it a seemingly ideal tool for precise measurements of glassware, plasticware, and other delicate items.
My experience often involves needing to measure internal and external diameters of custom ammunition components, as well as the dimensions of various firearm parts where tight tolerances are critical. Steel calipers can sometimes mar softer materials or be unsuitable for use around sensitive electronics, so a non-metallic alternative seemed promising. I was hoping to find a tool that provided adequate precision without the risk of damage associated with metal instruments.
Upon unboxing, the Bel-Art Plastic Calipers, SCIENCEWARE 134160001 Caliper With Dial immediately felt lightweight, almost surprisingly so. The plastic construction appeared reasonably robust, and the dial seemed clear and easy to read. The initial impression was of a functional, if somewhat utilitarian, instrument.
I considered other plastic calipers from brands like Mitutoyo and Fowler, but those models are significantly more expensive. I ultimately chose the Bel-Art Plastic Calipers, SCIENCEWARE 134160001 Caliper With Dial because of its balance between price and purported accuracy for laboratory use. My initial excitement was tempered by a slight skepticism regarding its long-term durability given its plastic construction.
Real-World Testing: Putting Bel-Art Plastic Calipers, SCIENCEWARE 134160001 Caliper With Dial to the Test
First Use Experience
My initial testing involved measuring various items in my reloading room: bullet diameters, case lengths, and primer pocket depths. I used the calipers to measure the outside diameter of several pieces of ammunition brass. The dial indicator made it easy to read the measurements to the nearest 0.1mm as advertised.
The calipers performed adequately in a controlled environment. However, the plastic jaws exhibited some flex, particularly when measuring objects with slight irregularities. The plastic construction felt flimsy when moderate pressure was applied.
The thumb roller provided smooth adjustment of the jaws, but the overall feel was less precise than my steel calipers. I noticed that the zero setting drifted slightly after only a few measurements, requiring frequent readjustment. This was a significant inconvenience.
Extended Use & Reliability
After several weeks of use, the Bel-Art Plastic Calipers, SCIENCEWARE 134160001 Caliper With Dial showed some signs of wear. The plastic jaws had begun to exhibit minor scratches and scuff marks. This suggested that the plastic may not be as durable as anticipated.
The accuracy also seemed to degrade over time. The dial indicator became slightly looser, making it more difficult to obtain consistent readings. Cleaning was relatively easy with a soft cloth and mild detergent.
Compared to my previous experiences with metal calipers, the Bel-Art Plastic Calipers, SCIENCEWARE 134160001 Caliper With Dial felt significantly less robust and precise. While suitable for basic measurements, it fell short of expectations for tasks requiring high accuracy and repeatability. The amount of flex in the jaws makes it ill-suited to tasks requiring consistent pressure.
Breaking Down the Features of Bel-Art Plastic Calipers, SCIENCEWARE 134160001 Caliper With Dial
Specifications
The Bel-Art Plastic Calipers, SCIENCEWARE 134160001 Caliper With Dial features a durable plastic polymer construction designed for measuring glassware and plasticware. The white dial has graduations in 0.1mm increments, allowing for precise readings, up to a maximum measurement of 150mm. This is an important consideration for those needing to measure larger objects.
The dial is adjustable for zero settings and differential measurements. This feature is useful for quickly comparing the sizes of different objects. The caliper’s Bel-Art Number is F13416-0001.
The Manufacturer‘s description states the calipers are designed to measure I.D., O.D., and depth. This provides versatility for a range of measurement tasks. The thumb roller allows for easy and controlled adjustment of the jaws.
Performance & Functionality
The Bel-Art Plastic Calipers, SCIENCEWARE 134160001 Caliper With Dial performed adequately for basic measurements in controlled laboratory environments. The dial indicator provided easy-to-read measurements. However, the plastic construction introduced some limitations.
The main weakness was the flex in the jaws, which affected accuracy and repeatability, especially when measuring objects with varying shapes or applying even moderate pressure. The lack of rigidity can lead to inconsistent readings. While it met basic expectations for non-critical measurements, it falls short for high-precision applications.
Design & Ergonomics
The caliper is lightweight and comfortable to hold. The plastic construction makes it suitable for use in environments where metal calipers might be problematic. However, the overall build quality feels somewhat flimsy compared to metal calipers.
The thumb roller is easy to use, but the dial indicator could be more robust. The absence of a locking mechanism for the jaws also detracts from the overall user experience.
Durability & Maintenance
The plastic construction of the Bel-Art Plastic Calipers, SCIENCEWARE 134160001 Caliper With Dial raises concerns about its long-term durability. The plastic is susceptible to scratches and wear. The dial indicator may also become loose or misaligned over time.
Maintenance involves simple cleaning with a soft cloth. Repairing damaged components is not feasible, making replacement the only option in case of breakage.
Accessories and Customization Options
The Bel-Art Plastic Calipers, SCIENCEWARE 134160001 Caliper With Dial does not come with any additional accessories beyond the basic instrument itself. There are no customization options available. This is a bare-bones tool focused on basic functionality.
