The IDB Model ID-939C is a next generation high sensitivity electrostatic field meter designed to provide accurate and reproducible measurements of Electrostatic Fields. ID-939C Precision Electrostatic Fieldmeter Building on the success of the popular ID-422 field meter the ID-939C comprises a sensing head which is cable connected to a Processor control and display unit. The unit is designed and constructed to a high standard so that observations are stable, accurate and reproducible. The separate sensing head is appropriate for extended duration studies in the laboratory or in reasonably clean industrial situations. SPECIFICATIONS & FEATURES Input Power Options: Sensitivity ranges: The ID-939C can be used in a stand-alone configuration or connected via a CAT5 Ethernet cable to a desktop or laptop computer for remote controlling. It is then possible to locate the equipment in a suitable environmental test chamber to control environmental parameters. A simple GUI (Graphical User Interface) is provided for controlling the instruments and storing test results. When used in stand-alone mode, the test results are displayed on a TFT colour touch-sensitive display mounted to the instrument’s front panel for ease of operation. Test data is stored on an internal SD card which can be down loaded to a laptop of PC using the supplied GUI. Sense Probe: Rotating Vane field meter Driven by internal DC motor; Resolution 480 x 272 Visible area 97mm x 57mm Probe Dimensions: Probe diameter 63mm, Length 145 mm, diameter of mounting flange 100 mm Processor Dimensions Self-Test & Maintenance: Please email [email protected] for further details.
