The leak detector ET97W represents the best solution on the market in terms of precision, flexibility and execution speed of seal tests with measure in flow rate.
This instrument allows to measure in a direct way the air flow generated by the leak-off rate.
ET97W is composed of a pneumatic circuit optimized in order to reduce the filling times, of a mass flow sensor, of a pressure
sensor and of an electronic pressure regulator, that guarantees stable and safe test pressures without the operator assistance.
The instrument detects the leaks through continuous seal measure of the pressurized piece, this method allows to reduce
drastically the time of the test phase.
ET97W is specially used in seal tests where the volume of the piece is unknown and variable (oil motors, elastics bags or
bottles), when the leak entity is so elevated that a Äp system does not succeed to maintain constant the test pressure (cartridge valves, oil distributors, between filaments) and finally when is requested a continuous leak measurement in order to allow the operator to look for and repair the same one.

The historic problem of flow test systems, especially for high flows, deals with keeping the
reference pressure regulated according to the wanted one while the flow changes.
The flow measurement depends directly (but not linearly) on the pressure and because of charge loss, we have to consider as pressure value the pressure at the entrance of the piece and not the one generated inside the piece.
In the past almost all leak and flow test producers tried to solve this by separating the connecting tubes to the piece between flow and pressure measurement in order to obtain at least a real pressure datum (even if not regulated) and by correcting through the software the eventual charge loss of connection tubes through correlation calculations.
The limits of this method are (especially with high charge loss -> 5 Lt/min) in the non linearity of flow/pressure.
Moreover in deforming pieces, where the pressure value modifies the matched flow value (packaging, filters, valves … and every piece which is not really rigid) this correlation changes drastically the wanted measurement value.
Through new proportional techniques about electronics and algorithm able to take a picture of the flow value (only at wanted values of pressure), the RFO techniques is a warranty of doing tests at the flow and pressure values you set.

Rigid Pendulum Type Physical Properties Testing Instrument, RPT-3000W
This instrument allows measurement of visco-elastic physical properties under a curing process and the surface layer physical properties of the material being measured and other materials such as inorganic materials like concrete, cosmetics, paper and foods. This means that the test method does not depend on the substrate. Therefore, this instrument has applications for the development/improvement, quality evaluation, designing, trouble-shooting, and the production line and life evaluation of materials.
All materials transform from a liquid state to a solid state through certain actions (heat, light, time and others) and produce various physical properties. The change in phase from a liquid to a solid causes various problems. The most important item to evaluate from among the various material evaluations is the change in age of the chemical-physical performances in the process of curing and drying from a liquid state to a solid state.
Measurement
Fix the test piece coating plate on the cooling/heating block. Set the pendulum so that the knife-edge, the fulcrum of the swing, comes vertically into contact on the test piece coated surface. Apply free vibration to the pendulum. For measurement of physical properties, use a cylindrical edge. By analyzing this vibration, the curing process and surface's physical properties can be evaluated.
Features
-Coating Thickness Resolution: 0.01 ìm - 7mm
-Period of Vibration:0.05 to 2.000sec
-Logarithmic Damping Ratio: 0.001 to 6.000sec
-Test Temperature: -100 to +400 degree Celsius
-Measurement Time: 1 to 9999 minutes

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.
