Vibration Test
-
Vibration testing determines the dynamic effects on component part of vibration within the frequency ranges and magnitudes that may be encountered during field service. Vibration, for example, causes loosening of parts or relative motion between parts in the specimen, producing objectionable operating characteristics, noise, wear, and physical distortion, and often results in fatigue and failure of mechanical parts.

Difference Amplifiers
-
A difference amplifier is a special purpose amplifier designed to measure differential signals, otherwise known as a subtractor. A key feature of a difference amplifier is its ability to remove unwanted common mode signals, known as common mode rejection (CMR). Unlike most types of amplifiers, difference amplifiers are typically able to measure voltages beyond the supply rails, and are used in applications where large dc or ac common-mode voltages are present. They are ideal for current and voltage monitoring. Analog Devices offers a range of difference amplifiers, optimized for low distortion, low power, or high voltage performance.

63800 series
-
The Chroma 63800 Loads can simulate load conditions under high crest factor and varying power factors with real time compensation even when the voltage waveform is distorted. This special feature provides real world simulation capability and prevents overstressing thereby giving reliable and unbiased test results. The 63800's state of the art design uses DSP technology to simulate non-linear rectified loads with its unique RLC operation mode. This mode improves stability by detecting the impedance of the UUT and dynamically adjusting the load's control bandwidth to ensure system stability. Comprehensive measurements allow users to monitor the output performance of the UUT. Additionally, voltage & current signals can be routed to an oscilloscope through analog outputs. The instrument's GPIB/RS232 interface options provide remote control & monitor for system integration. Built-in digital outputs may also be used to control external relays for short circuit (crowbar) testing.

Moisture Meters
-
Moisture Meters fall into two categories, pin-type and pinless. Pin-type Moisture Meters measure the resistance between test pins inserted into a piece of wood or a building material and use that reading as a proxy for the object''s absolute moisture level. The wetter the material, the less ready it is to be sanded, painted, finished or covered. A best seller is the MMD4E Pin-Type Moisture Meter. Pinless Moisture Meters rely on the ability of moisture to inductively distort an electric field created by turning on the meter. Although Pinless Moisture Meters can only make relative readings, they are nonetheless useful for pinpointing the source of a leak above a ceiling, and for leaving no unsightly pinholes on a finished surface. The MMD7NP is a best selling pinless moisture meter.
