Liquid-In-Glass Thermometers. A liquid-in-glass thermometer is the simplest and most commonly employed type of temperature measurement device. It is one of the oldest thermometers available in the industry. It gives fairly accurate results within the temperature range of -200 to 600Â°C. No special means are needed to measure temperature via these thermometers.
This brings us to the definition of detection or reporting limits. The smallest concentration (or amount) of analyte, that can be reported by a laboratory is called reporting limit. AIHA requires RL (reporting limit) which is LOD times a safety factor selected by the laboratory.
Definition - What does Permissible Exposure Limit (PEL) mean? Permissible exposure limit (PEL) is the legal limit in the U.S. for maximum concentration of any chemical in the air to which a worker may be exposed continuously for eight hours without any danger to health and safety. PEL is established by the Occupational Safety and Health Administration (OSHA).
