ORP sensors work by measuring the electrical potential (voltage) between two electrodes in contact with water. Both electrodes are often contained in a single unit called a combination electrode. One electrode is called the indicator electrode, and it is usually made of platinum (other materials su...
Control the oxygen concentration in the breathing loop. Solid-state oxygen sensors monitor the partial pressure of oxygen in the breathing loop and send this information to a microprocessor that controls the oxygen-delivery system. You'll find three types of rebreathers: oxygen, semi-closed circuit...

Devices like the Alcosensor III and IV use fuel cell sensors. The fuel cell has two platinum electrodes with a porous acid-electrolyte material sandwiched between them. As the exhaled air from the suspect flows past one side of the fuel cell, the platinum oxidizes any alcohol in the air to...
To comprehend how we can gain access to such precise numbers, we have to ask ourselves: how does a breathalyzer work? What do those figures mean? And how do police officers find out if someone they suspect has been drinking is actually legally drunk? Many officers in the field rely ...
Humidity probes detect changes that alter the temperature or electrical currents in the air. There are three main types of sensors: capacitive, resistive…
Despite their numerous advantages, thermocouples do have some limitations. One of the primary drawbacks is their accuracy, which can be less than that of other types of temperature sensors. They also produce a non-linear output, meaning that the relationship between temperature and voltage is not ...
