A refractometer is a simple instrument used for measuring concentrations of aqueous solutions. It requires only a few drops of liquid, and is used throughout the food, agricultural, chemical, and manufacturing industries.

A lensmeter or lensometer, also known as a focimeter or vertometer,[1][2] is an ophthalmic instrument. It is mainly used by…[Читать далее]

Highway Roller Barrier is designed to prevent vehicles from colliding with obstacles, or to prevent wrong vehicles from entering the opposite traffic flow, which can reduce the occurrence of head-on collisions.

Bridge Piers Against Collision is a protective device installed on or around the pier to protect the bridge. Its main purpose is to avoid…[Читать далее]

Shrink sleeve labels are full-color, 360-degree printed labels that utilize heat in the application process to conform the label to the shape of the container.

PETG Shrink Sleeves use PETG (Polyethylene Terephthalate Glycol) as the most heat resistant shrink sleeve material. They have high scuff resistance and excellent clarity.

PVC Shrink…[Читать далее]

Integrated circuit (IC), also called microelectronic circuit, microchip, or chip, an assembly of electronic components, fabricated as a single unit, in which miniaturized active devices (e.g., transistors and diodes) and passive devices (e.g., capacitors and resistors) and their interconnections are built up on a thin substrate of semiconductor…[Читать далее]

Fastener Parts are hardware devices that mechanically joins or affixes two or more objects together.

Bolts and Screws are fasteners. A bolt is a non-tapered fastener that uses a washer and nut to hold objects together. A screw is a tapered fastener that mates with an existing thread or creates its own thread in a material as it turns.

A standardized extract is created by “pulling out” (extracting) specific compounds from a plant. Standardized Saw Palmetto Berry Extract, for example, is extracted from the fresh berries of the saw…[Читать далее]

Wired Earphones receive an analog signal, which can handle more data than Bluetooth®. Therefore, it offers better sound quality. Ubiquity: As long as there’s a 3.5mm input, wired headphones can connect to any audio source, from your dad’s Walkman to your brand-new laptop.

The neckband earphones allows for a combination of features you rarely…[Читать далее]

A nickel metal hydride battery (NiMH or Ni–MH) is a type of rechargeable battery. The chemical reaction at the positive electrode is similar to that of the nickel–cadmium cell (NiCd), with both using nickel oxide hydroxide (NiOOH). However, the negative electrodes use a hydrogen-absorbing alloy instead of cadmium. NiMH batteries can have two to…[Читать далее]
