Equipment - Environmental TestersEnvironmental testers are instruments used to measure and test a wide range of environmental parameters, such as temperature, humidity, pressure, and air quality. They are commonly used in applications such as meteorology, HVAC, and industrial manufacturing. Environmental testers may be portable or stationary, and may be designed for use in specific environments, such as indoors, outdoors, or in hazardous locations. Some examples of environmental testers include thermometers, hygrometers, barometers, and air quality monitors. These instruments may be standalone devices or may be integrated into larger systems, such as weather stations or building automation systems.
