E

Elektromagnetische straling, normen voor -

Internationale normen die de elektromagnetische uitstraling van monitoren aan banden leggen. Er zijn op dit moment twee belangrijke normen die beide zijn afgeleid van Zweedse voorschriften.

MPR-II

Deze norm is oorspronkelijk voorgesteld door de Zweedse Raad van Meten en Testen: geeft maximale waarden voor de elektromagnetische straling van een monitor en is inmiddels als wereldstandaard geaccepteerd. MPR-II definieert maximaal toegestane elektrostatische, magnetische en elektrische velden gemeten op een afstand van 50 cm van het midden van de monitor (zie tabel).

TCO

In 1991 ontwikkelde de Zweedse Tjänstemannens Central Organization (TCO, Zweedse Confederatie van Professionele Werknemers) een norm die nog strenger was dan MPR-II, met name voor elektrische wisselvelden. Vergeleken met MPR-II zijn niet alleen de maximaal toegestane velden verlaagd, maar is ook de meetafstand verkleind (zie tabel).

Elektromagnetische-stralingsnormen

EMI (Electrical Magnetic Interference)

De elektrische en/of magnetische straling die wordt uitgezonden door een werkend elektrisch of elektronisch apparaat.

EMS (Electrical Magnetic Susceptibility)

De mate waarin elektrische of elektronische apparatuur goed kan functioneren in een omgeving met elektrische en/of magnetische interferentie.

The monitor utilizes CRT (Cathode Ray Tube) technology, a standard in earlier generations of monitors, which contributes to its deep color reproduction and high refresh rates. Users benefit from a refresh rate of up to 85Hz, significantly reducing flickering and providing a smoother visual experience, particularly during prolonged use.

In terms of ergonomics, the Philips 109B features a tilt-adjustable design, allowing users to customize the angle of the screen to their preference, thus enhancing comfort during extended viewing sessions.

This makes it compatible with a wide range of computers and peripherals, ensuring easy integration into existing setups without the need for additional adapters or converters.

Moreover, the monitor includes various color settings, allowing users to adjust their viewing experience according to their personal preferences, which can be particularly beneficial for graphic work or video editing where color accuracy is important.

Overall, the Philips 109B exemplifies a practical, user-friendly monitor that caters to a variety of computing needs. Its combination of size, resolution, ergonomic features, and solid build quality makes it a commendable choice for users seeking a functional monitor without unnecessary frills.
