The top-of-the-range testo 816-1 dB meter for sound level measurement complies with all requirements with regard to the execution of non-conform sound level measurements according to IEC 61672-1 Class 2 and ANSI S1.4 Type 2. This makes it suitable for carrying out sound level measurements in the workplaces as well as in public places, industry and production. The testo 816-1 has all the features which its little variant, the testo 816, has but also comes with a built-in data logger that can save up to 31 000 readings and dedicated PC software. The dB meter for pros: measure, save, analyse The testo 816-1 also comes with a practical all-in-one carry bag and a whole host of technical features and benefits designed to allow you to carry out professional sound level measurements as a part of health and safety inspections and immission controls. Benefits include being able to change the measuring rate from slow (one measurement per second) to fast (one measurement every 125 milliseconds) depending on the type of measurement, and being able to select between two frequency measurement types: the characteristic curve A corresponds to the way the human ear perceives sound pressure while the characteristic curve C measures the low frequency percentage of the sound.

The reliable, repeatable, accurate way to check bearings and overall vibration. Make go or no-go maintenance decisions with confidence. The Fluke 805 Vibration Meter is the most reliable vibration screening device available for frontline mechanical troubleshooting teams that need repeatable, severity-scaled readings of overall vibration and bearing condition. External sensor is also available to measure overall vibration but it’s an optional accessory. What makes the 805 the best choice?   A meter – not a pen – that measures overall vibration as well as specific variables like bearing condition and temperature, to provide a more complete picture.   A combination vibration and force sensor tip that compensates for user variance (force or angle) yielding accurate, repeatable readings.   A four-level severity scale and onboard processor calculate bearing condition and overall vibration using easy-to-understand textual alerts (Good, Satisfactory, Unsatisfactory, Unacceptable).   Sensor sensitivity can read a wide range of frequencies (10 to 1,000 Hz and 4,000 to 20,000 Hz) covering most machine and component types.   Straight-forward user interface that minimizes the user inputs to RPM range and equipment type. Features and Benefits   Innovative sensor design helps minimize measurement variations caused by device angle or contact pressure   Consistent data quality at both low and high frequency ranges   Four-level scale indicates severity of problems for overall vibration and bearing condition   Exportable data via USB   Trending in Microsoft® Excel using built-in templates   Overall vibration measurement (10 Hz to 1,000 Hz) for acceleration, velocity and displacement units of measurement for a wide variety of machines   Crest Factor+ provides reliable bearing assessment using direct sensor tip measurements between 4,000 Hz and 20,000 Hz   Colored lighting system (green, red) and on-screen comments indicate how much pressure needs to be applied to take measurements   Temperature measurement with Infrared Temperature Sensor increases diagnostic capabilities   On-board memory holds up to 3,500 measurements   Audio output for listening to bearing tones directly   External accelerometer support for hard to reach locations   Flashlight for viewing measurement locations in dark areas   Large screen with high resolution for easy navigation and viewing Use the 805 to check the following machine categories: (37 machine categories totally) Chiller (refrigeration)   Reciprocating (Open motor and compressor separate)   Reciprocating (Hermetic motor and compressor)   Centrifugal (Hermetic or Open Motor Fans   Belt-driven Fans 1800 to 3600 RPM   Belt-driven fans 600 to 1799 RPM   General direct drive fans (direct coupled)   Vacuum blowers (belt or direct drive)   Large forced draft fans (fluid film brgs.)   Large induced draft fans (fluid film brgs.)   Shaft-mounted intergral fan (extended motor shaft)   Axial flow fans (belt or direct drive) Cooling tower drives   Long, hollow drive shaft (motor)   Belt drive (motor and fan - all arrangements)   Direct drive (motor and fan - all arrangemetns Centrifugal Pumps Note: height is measured from grade to top motor bearing   Vertical pumps (12’ to 20’ height)   Vertical pumps (8’ to 12’ height)   Vertical pumps (5’ to 8’ height)   Vertical pumps (0’ to 5’ height)   Horizontal centrifugal end suction pumps – direct coupled   Horizontal centrifugal double suction pumps – direct coupled   Boiler feed pumps (turbine or motor driven) Positive Displacement Pumps   Positive displacement horizontal piston pumps (under load)   Positive displacement horizontal gear pumps (under load) Air compressors   Reciprocating   Rotary screw   Centrifugal with or without external gearbox   Centrifugal – internal gear (axial meas.)   Centrifugal – internal gear (radial meas.)

The original Crest Factor is used by vibration analysts to identify bearing faults. It is defined as the ratio of the peak value/RMS value of a time domain vibration signal. A key limitation of the original Crest Factor algorithm is that it does not increase linearly as the bearing degrades, making it very difficult to determine the severity of mechanical issues. In fact, the Crest Factor can actually decrease as a bearing nears catastrophic failure due to large RMS values. In order to overcome this limitation, Fluke uses a proprietary algorithm known as Crest Factor+ (CF+). CF+ values range from 1 to 16. As the bearing condition worsens, the CF+ value increases, ensuring the user is easily able to recognize the severity of the problem. To make things even simpler, Fluke has also included a four-level severity scale that identifies the bearing health as Good, Satisfactory, Unsatisfactory or Unacceptable.
