Glossary of terms used on this site

Term Main definition
Maintenance and repair
Any action that has the goal of keeping a piece of equipment in perfect working order or returning it to perfect working order. 7Solutions has its own maintenance and repair departments with decades of experience maintaining and repairing any type and brand of gas detection equipment.
Material Safety Data Sheet (MSDS)
An information sheet that describes the safety properties of a material, including guidelines for its safe handling, storage and transport. Includes toxicity information, usually along with maximum exposure warnings (TWA, STEL and/or ceiling values).
Measurement and control technology
Any piece of equipment that is designed to measure certain parameters and to take action upon the measurement results, usually when controlling (production) processes. Gas detection, in various degrees of specialty, form an important group of measurement instruments on which control actions are based.
Measuring cases
Any system in a case that forms an integrated solution for a fixed set of circumstances or a fixed measurement need.
Measuring heads
In gas detection, sensor units.
Methane, (CH4)
Geiger counters and X Ray Fluorescence detectors make use of methane when used in combination with argon. Methane, (CH4) CAS #74-82-8 UN1971; UN1972, can also be put into a mixture with hydrocarbons when looking for the PCI of coal or hydrocarbons. In this use, it is a reference point for measurements that are calorimetric. Other uses of methane include calibration, monitoring, and analyzing in various petrochemical and environmental industries.
Micrometer (
A measurement of length that equals 1 x 10-6 meters, or 1/1,000th of a millimeter.
Mole
The SI unit for amount of substance, defined as 6.02214076
Molecular Mass
The mass of a given molecule, expressed in Daltons, the unified atomic mass unit. The unit is chosen so that a mole of a substance (6.02214076
Monitoring
To observe and check progress or quality of something over a period of time, to keep under systematic review. In gas detection, this pertains to a device that monitors the concentration of its target substance in real-time, notifying its user when the detected concentration falls outside preset thresholds. All portable gas detectors with few exceptions fall into this category, which means the number of gas monitors is vast. Monitors can have subtly different characteristics as to their monitoring specifications, making it important to obtain expert advice as to which monitor to use in specific situations. 7Solutions, with its decades of experience in every gas detection situation imaginable, is ideally placed to provide this advice.
Multi gas detection
Any electronic system that can monitor and alarm for more than one target gas simultaneously. Usually, Multi gas detectors can be equipped with many combinations of different sensors, of which oxygen and LEL sensors are usually two. Some multi gas detectors can also contain a Photo Ionisation Detection (PID) sensor, a CO2 sensor or some other specialty sensor. They are equipped with a battery, alarm functions and communication, either to transfer detected values to a computer or to transfer real-time readings to a central monitoring location. A tendency is taking place to miniaturize "simple" multi gas detectors and to add ever more functions to more complex and costly multi gas detectors. 7Solutions has mixed experiences with most of these devices and can give you a great advice for what to look for in your next gas detector.
