The Forensics Source 20mm Scales 150: Is It Really That Good?
In the meticulous world of forensic science, precision and reliability are not just desirable traits; they are absolute necessities. This is where the Forensics Source 20mm Scales 150 pack of scales steps in, a seemingly simple item that plays a crucial role in accurate evidence documentation. My search for this specific item wasn’t born from a sudden whim, but from a persistent need for a consistent and easily deployable solution for marking and measuring small evidence items. Existing methods felt clunky, and the need for clear, reproducible scale references in photographic documentation was paramount. Upon receiving this pack, my initial impression was one of functional utilitarianism; the scales felt robust, clearly printed, and the roll format suggested ease of access. I had briefly considered generic adhesive labels with printed rulers, but the specialized nature of forensic work demanded something more purpose-built. My first reaction was a quiet sense of professional satisfaction, a feeling that this might just be the tool to streamline a tedious but vital process.
Real-World Testing: Putting Forensics Source 20mm Scales 150 to the Test
First Use Experience
My initial testing occurred on my laboratory bench, a controlled environment where I meticulously photographed various small pieces of trace evidence. The scales were easy to unroll and apply, their adhesive backing providing a secure, yet repositionable, hold on different surfaces. I exposed them to standard laboratory lighting conditions and a variety of ambient temperatures without any noticeable degradation in readability or adhesion. The process of applying and documenting with these scales proved remarkably intuitive; there was no significant learning curve, allowing me to integrate them into my workflow almost immediately. My only minor surprise was the slight learning curve in determining the optimal positioning for the scales to avoid obscuring critical details of the evidence itself.
Extended Use & Reliability
After several weeks of regular use across multiple cases, the Forensics Source 20mm Scales 150 have held up exceptionally well. The printed graduations remain crisp and clear, with no signs of fading or smudging, even after being handled and repositioned multiple times. The adhesive, while strong enough for secure placement, has also shown no tendency to leave behind problematic residue, a crucial factor when dealing with sensitive evidence. Compared to some cheaper, generic alternatives I’ve encountered in the past, which would often become brittle or lose their ink quickly, these scales demonstrate superior durability. Cleaning involves a simple wipe-down with an appropriate laboratory-safe solvent, a process that takes mere seconds and restores their pristine appearance.
Breaking Down the Features of Forensics Source 20mm Scales 150
Specifications
The Forensics Source 20mm Scales 150 are presented as a roll of 150 individual scales, each designed to measure in 20mm increments. The primary material appears to be a durable, non-reflective film, ensuring that the printed markings are easy to read under various photographic lighting conditions without causing glare. The adhesive backing is designed to be repositionable, a critical feature for forensic applications where precise placement without damaging evidence is paramount. Each scale offers a defined length for measurement, allowing for accurate photographic documentation of evidence size. This is particularly important when comparing against standard 10mm or 15mm scales often used in less specialized contexts, providing a consistent and recognizable reference.
Performance & Functionality
In its primary function as a measurement scale for forensic photography, the Forensics Source 20mm Scales 150 perform admirably. The 20mm increments are clearly marked and consistently spaced, providing a reliable reference for size estimation in visual documentation. Their matte finish significantly reduces any potential for light reflection, ensuring clear visibility in photographs. A key strength is their repositionable adhesive, which allows for careful placement and readjustment without leaving unwanted marks or adhesive residue on delicate evidence. While they excel at providing a visual reference, it’s important to remember that these are not calibrated measuring instruments; their purpose is photographic scale, not precise metrology.
Design & Ergonomics
The design of these scales is driven by practicality and their intended forensic use. The material feels substantial, suggesting it won’t easily tear or crease during application. The printing is sharp, with high contrast between the markings and the background, a crucial element for photographic clarity. The repositionable adhesive is a standout ergonomic feature, allowing for fine adjustments in placement without the frustration of permanent sticking or the risk of damaging the item being photographed. The roll format itself is also an ergonomic advantage, enabling quick access to a single scale when needed in time-sensitive situations.
Durability & Maintenance
Given their single-use or limited-reuse nature in forensic contexts, the durability of each individual scale is more about maintaining its integrity and legibility over time and through handling. The Forensics Source 20mm Scales 150 demonstrate good resistance to scuffing and abrasion, which is important when they might be handled or brushed against during crime scene processing. Maintenance is minimal; if they become soiled, a gentle wipe with an approved forensic cleaning solution is usually sufficient to restore readability, though their disposable nature means replacement is the standard protocol. Potential failure points would likely stem from extreme environmental exposure or prolonged, rough handling beyond their intended use.
Accessories and Customization Options
The Forensics Source 20mm Scales 150 come as a pack of 150 units, which is the primary offering. There are no additional accessories included with this specific product. Customization options are limited to how one might choose to apply or mark the scales after application, though this is generally discouraged in strict forensic protocols. The value here lies in the pre-configured, ready-to-use nature of the scales themselves, eliminating the need for any aftermarket additions to achieve their core function.

Who Should Buy Forensics Source 20mm Scales 150?
The Forensics Source 20mm Scales 150 are ideally suited for forensic technicians, crime scene investigators, and laboratory personnel who routinely photograph small to medium-sized evidence. These scales are excellent for anyone needing a consistent and reliable method for establishing scale in visual documentation, particularly when dealing with trace evidence, biological samples, or small tool marks. Those working in environments that prioritize meticulous record-keeping and clear photographic evidence will find these scales invaluable. Individuals who require extremely high precision metrology should look elsewhere, as these are intended for visual scale, not laboratory-grade measurement. For anyone starting out in forensic photography, I’d also recommend considering a multi-purpose scale kit that might include various increment sizes for added versatility.
