...of ambient noise. The C-weighting simulates the frequency properties of high-intensity noises of the human ear, which are suitable for the sound pressure analysis of machine motors and machines. More professional measurement methods provide users with a more perfect user experience.
❤【Fast and Slow Response Rate Conversion】 The spl meter has the function of converting the fast and slow response rate. The fast response rate uses a time constant of 125 milliseconds for general environmental measurement. The slow response rate uses a 1 second time constant, which is used for environmental measurements with relatively large changes in noise levels.
❤【Maintain the Maximum Value】Long press the MAX key to lock the maximum value measured during the measurement. Note that db meter does not have data logging and saving capabilities. If there is no operation for 10 minutes, the sound meter will automatically turn off.

The AD8015 is a wide bandwidth, single supply transimpedance amplifier optimized for use in a fiber optic receiver circuit. It is a complete, single chip solution for converting photodiode current into a differential voltage output..
The 240 MHz bandwidth enables AD8015 application in FDDI receivers and SONET/SDH receivers with data rates up to 155 Mbps. This high bandwidth supports data rates beyond 300 Mbps. The differential outputs drive ECL directly, or can drive a comparator/ fiber optic post amplifier..
In addition to fiber optic applications, this low cost, silicon alternative to GaAs-based transimpedance amplifiers is ideal for systems requiring a wide dynamic range preamplifier or singleended to differential conversion..
Application: Fiber Receiver: SONET/SDH, FDDI, Fibre Channel Stable High Capacitance Detector.

115V AC digital stroboscope with xenon flash tube and adjustable flash rate is designed for motion analysis, preventive maintenance, printing inspection, harmonics analysis, and speed measurement of repetitive motion.
Flash rate range of 30 to 10,000 flashes per minute (FPM) and built-in multiply-by-2 and divide-by-2 functionality provides still images and verification of speed measurement.
Xenon flash tube with 8 to 20 microsecond flash duration provides crisp images in brightly lit areas.
Internal phase shift allows the operator to manually rotate the target location clockwise or counterclockwise in 5 degree increments.
115V AC power and continuous duty cycle provide long-term use without overheating.
