Oxygen Detector offers a critical safeguard when a laboratory environment’s safety and success hinge on the delicate balance of inert gases. These lifelines alert researchers to hazardous shifts in gas levels that might compromise experiments and pose a risk of fire or explosion, providing immediate response to avert disaster and enabling uninterrupted research. This active monitoring fosters a focused environment where scientists can pursue breakthrough discoveries without distraction or concern for environmental conditions.
Oxygen Detector: Ensuring Safe and Healthy Environments
There are two primary styles of oxygen sensor technology: electrochemical (Clark-style/amperiometric) and optical (luminescent). The specific characteristics that define each style make them more suitable for different environments. Selecting the right oxygen sensor for your needs requires a careful consideration of these traits, as well as an assessment of operating temperature range and compatibility with existing lab equipment.
A Clark-type oxygen sensor utilizes a cathode and an anode submerged in an electrolyte, with the anode reducing the oxygen by diffusion to produce a measurable electric current. This sensor can detect oxygen concentrations between 0% and 100% saturation in water. It is insensitive to stirring and is insensitive to oxygen consumption, but the sensitivity decreases as the sensor nears saturation.
A luminescent oxygen sensor consists of an LED light and an external cap with an oxygen-sensitive fluorescent dye layer. The light illuminates the dye layer, and when oxygen comes in contact with it, the wavelengths are shifted to create a readable signal. This sensor can detect oxygen concentrations between the ppm range and saturation in water.
