Testo 0563 8155 815 Sound Level Meter The Testo 815 Sound Level meter is the ideal instrument for daily use. Whether its for air conditioning or heating. ... moreIndustrial noise, building demolition, machine noise, active volcanism, or noise in combustion systems, the Testo 815 is the ideal unit. Sound waves are fluctuations in air pressure. If they are audible to the human ear we talk about audible sound. The fluctuations in pressure occurring with audible sound are extremely low. At a normal pressure of 1013 mbar even changes in the μPa range can stimulate the human ear. A suitable pressure sensor with the appropriate sensitivity is the microphone. Sound level meters have been designed for measurements in the free field. There is also a free field if the level falls by 6 dB per duplication of the distance from the source. This is the case in most rooms. Examples: Office with carpet. Curtains and partitions = Free field Cellar with concrete walls. Without furniture, highly reverberant = Reverberant field Measuring tips: Measuring conditions are ideal if there are absolutely no interfering objects in the sound field. This would be the case. For example, on top of a mountain. Because there are no walls or ceilings on which sound can be reflected, free dispersion is guaranteed(free field) In a closed room there is usually a wall opposite the noise source. This can cause reflections which distort the measured result(reverberant field) With the Testo 815 you get superior microphone sensitivity and precise sound measurements year after year. 815 Features: Accuracy class 2 according to IEC 60651 Easy to adjust(calibration screwdriver included) Frequency weighting according to characteristic line A and C Maximum and Minimum memory Built in 1/4 inch stand screw Switchable time weighting Fast/ Slow Microphone Wind protection cap Battery Technical Data: Measuring Range: +32 to +130 dB Accuracy ±1 digit: Class 2 ±1.0 dB Resolution: 1 dB Operating Temperature: 0 to +40 degrees C Storage Temperature: 10 to +60 degrees C Ba

ETCR2100C+ Clamp Ground Earth Resistance Tester 0.01-1200Ω Φ32mm 0.00mA-20.0A 1. Introduction ETCR Clamp Earth Resistance Tester is widely applied in ... moreground resistance measurement. Loop resistance measurement in fields such as electric power, telecommunications, meteorology, oil field, architecture and industrial electrical equipment, etc. When measuring ground system with loop, there is no need to disconnect the ground wire without auxiliary electrode, which means safer and faster. ETCR Clamp Earth Resistance Tester can measure the ground fault which can not be measured by traditional method, can apply in the occasion where traditional methods are unworkable; ETCR Clamp Earth Resistance Tester measures the integrated value of ground resistance and resistance lead. 2.Technical Specifications Function Ground resistance test.
