A&D's pipette accuracy testers provide a simple, precise, and cost-effective means for managing the accuracies of your pipettes by yourself.
The testing procedure is based the gravimetric method, which is the most commonly used test for the accuracy of variable-volume pipettes and is recommended by the ISO8655. In the gravimetric method, pipette volume is determined based on the mass value of the distilled water dispensed from the pipette. The high precision, accuracy, and speed of A&D's balances therefore ensure as effective testing as possible.
A&D’s pipette accuracy testers are equipped with various devices to facilitate your testing. Firstly, the evaporation trap, which prevents the evaporation of the dispensed water by maintaining high humidity inside, can minimize errors due to loss of evaporation. Secondly, the entire pipette accuracy tester set can be packed in a portable carrying case. This makes it easy to perform tests on-site, instead of collecting all the pipettes at one site for testing. Finally, the WinCT-Pipette software automatically converts mass values into volumetric values using the liquid temperature and barometric pressure previously entered. It is also possible to print an A4 or letter-size report including test conditions, data, judgment results, etc.
Three models are available depending on what volumetric range is to be measured. With A&D’s pipette accuracy tester, you can now easily and correctly screen out pipettes that need adjusting or repairing, eliminating the unnecessary costs of having all your pipettes inspected regularly by an outside contractor.
Please see the Pipette Accuracy Testers catalog for further details.

NonDestructive Evaluation [NDE] or NonDestructive Testing [NDT] is widely used to examine critical components either during the manufacturing process or while these components are in use. The computer simulation of NonDestructive methods now makes it practical to explore new ideas and approaches for assessing the quality of a component.
CIVA is a pioneer in providing NDE simulation. It provides one with the opportunity to simulate NDE physics and to post-process and review an actual inspection solution in order to determine reliable flaw detection.
CIVA presently comes with the following types of physics technologies:
- Ultrasonic Testing [UT]
- Eddy Current Testing [ET]
- Radiographic Testing [RT]

PXI is a test, measurement, and control platform designed for demanding applications that require maximum uptime and a high level of reliability. The PXI specification ensures this with requirements such as a rugged Eurocard form factor and forced-air cooling. Moreover, PXI products from National Instruments are designed, manufactured, and tested with the goal of delivering the highest quality products for the most demanding applications. For example, during new chassis development, Flotherm modeling is used to optimize cooling within the chassis card cage and power supply. During the development testing stage, empirical testing is performed to ensure these cooling levels have been achieved. Another example is the fact that PXI chassis, controllers, an modules from NI undergo highly accelerated life testing (HALT) during development testing to ensure product design margins and, in turn, reliability. These, along with the many other practices that NI employs during design, manufacturing, and test, result in PXI products of the highest quality and reliability. This is evident when you examine both the product's quality and reliability specifications, for example, mean time between failures (MTBF), and the tens of thousands of systems that have been deployed into the most demanding applications around the world, such as nuclear power plant inspection. However, all electronic devices have some failure rate. Not even the most reliable electronic systems (medical monitoring equipment, data servers in financial institutions, etc) are emune to failures, rare as they may be. In order to help you reduce the risk and maximize the uptime of your PXI system, this white paper presents best practices to follow during assembly, deployment, and maintenance. Additionally, if you do experience a failure, the techniques it discusses will minimize the downtime of your PXI system.

TEST/DISCONNECT TERMINALS( WGO 3)
Test/Terminal blocks are used to perform required test without switching off the power in the system.These products are installed at the secondry side of current transformers,and thus, electrical ratings can be observed by testing equipment connected to the product.In addition, it is possible to perform all required test without disconnecting the ammeter.In order to change a defected ammeter, secondary side of the transformer is short-circuited, and afterwards,the ammeter is disconnected securly.In the new generation test/disconnect terminal blocks named WGO 3 the connection surface area of the sliding bridge has been increased by 10 times.Thanks to sliding bridge and insulated test socket, the component is safe and functional, and short circuiting is easy.Another advantage of these new products is that the sliding bridge remains concrete due to bridge holder pins.Comb connectors can also be used with WGO 3.

Conventional AC test transformers are especially designed for testing objects of medium capacitance. These systems are particularly suited for tests requiring stable voltage even if the load changes under voltage (corona, wet & pollution tests) or when the load is inductive (inductive voltage transformers).
The possibility of stacking several of these transformer modules allows reaching very high voltage levels by keeping reasonable floor space.
