Charge Decay Meters

ID-917

The ID917 Charge Decay Meter is a general purpose electrostatic instrument designed for assessing the charge decay properties of films and plastics.

The test sample is simply loaded into a two-part sample holder which is then loaded into the instrument where the instrument can then operate in a stand-alone configuration or with a PC or laptop over the USB interface to test the film with either positive or negative test Voltages of either 1kV or 5kV – all user selectable.

The instrument will then plot the decay time on the TFT display - and the computer if connected – printing the decay time measured to one of either two pre-set measurement points of 50% discharge or 90% discharge. These discharge points can also be set by the customer to one of their choosing.

The graphical display prints the discharge curve in real-time sampling the magnitude of the electrostatic field at intervals from 10ms, 100ms, 1s to 10s which again is selectable by the user.

Test results can be stored on the computer for off-line analysis.

ID-913

The ID-913 provides the hardware platform to test the electrostatic protection properties of protective clothing and specifically the measurement of charge decay.

The instrument conforms to the mechanical and electrical parameters described in British Standard BS EN1149-3:2004 Inductive Charging (test method 2).

Testing is carried out by sliding the drawer containing the sample holder from the instrument and loading the test sample onto the sample holder. The sample holder is constructed to ensure the sample is located parallel to but not in contact with a high Voltage electrode. A clamping ring holds the sample in place as the drawer is then loaded into the instrument by closing the sample drawer. The test is then run and the results displayed on the TFT display.

Completely self-contained, the instrument can be used in either a stand-alone configuration or controlled over USB from a PC or Laptop.

ID-923

The ID-923 is a compact instrument which can be used within a test chamber where control of temperature and humidity is desired when testing the electrostatic properties of protective clothing.

The instrument conforms to the mechanical and electrical parameters described in British Standard BS EN1149-3:2004 Inductive Charging (test method 2).

Completely self-contained, the instrument can be used in either a stand-alone configuration or controlled over USB from a PC or Laptop.

Prior to loading the test sample. the instrument measures the maximum field strength available. The test sample is then loaded onto the sample holder located on the top of the instrument. A clamping ring holds the sample in place and the test is then run with results displayed on a TFT display located on the front of the instrument. If controlling the ID-923 over the USB interface, results are displayed in real time on the controlling PC or laptop where test results can also be stored.
