A solenoid is an electromagnetic switch that consists of a coil of wire with a ferrous metal core, often made out of iron. When a current passes through the coil, a magnetic field is induced in a predetermined direction, which in turn moves the core in a piston action. The movement of the core, or […]
Carbon monoxide gas alarms are an important safety precaution in areas where the invisible, odourless gas may be present. Carbon monoxide, chemical symbol CO, cannot be seen, smelled or tasted, but is poisonous to humans with symptoms ranging from dizziness, chest pain and vomiting, to unconsciousness and death. According to London Fire Brigade, each year […]
Recently we covered some of the top cave diving spots in the UK, but that’s not all the beautiful UK coastline has to offer… The UK contains over 130 permanently inhabited islands, so it has plenty of coastline to explore – and that means the best sailing spots in the UK can compete on the […]
COVID-19 is a respiratory illness and because of this, one of the significant challenges to effective treatment is the need to supply enough oxygen to the patient. In the early stages of the Coronavirus outbreak in the UK, much of the focus was on manufacturing enough ventilators to cope with the number of intensive care […]
Envin Scientific’s extensive range of gas sensors covers a wide variety of different applications for detecting and monitoring different gases and common atmospheric conditions like temperature and humidity. Because of this, we break down our Gas Sensors category into several sections, grouping together gas detectors and gas analysis equipment with similar characteristics. Here we’ll take […]
At Envin Scientific we supply two main types of optical filters, which can cater for a wide range of different characteristics and properties. The two types of optical filters we supply are: Optical thin film filters and coated filters Absorption and spectral filters Within both of these categories, there is a huge variation of different […]
Optical filters make use of the physical properties of different materials to affect the light that passes through (or reflects from) the surface of the filter. This can achieve a variety of effects. Bandpass filters transmit a range of wavelengths, whereas narrowband filters may only allow a single frequency of light through. Some, such as […]
