Product Information The SigmaCheck 2 complies with the requirements of the following inspection procedures: Boeing BAC5651 Airbus AITM 6-6004 ASTM E1004 AMS2658 BS EN 2004 MIL-STD-1537 Bell Helicopter BPS 4453 Key Features Built-in Lithium Ion Battery User programmable display 2GB of data storage. Able to store over one million data points Uploaded data can be viewed using MS Excel Intelligent charger via Micro USB Port Multiple languages available – English, French, German, Spanish. Excellent resistance to “edge effect” Rapid Display of Conductivity Results Battery life up to 12 hrs. Firmware can be upgraded in field Different probes may be configured by loading the appropriate probe map from SD Card Real-time clock for time and date so that readings can be “time stamped” Real-time PC control via USB or optional RS232 link Applications Material verification / sorting Heat treatment verification Heat or fire damage investigation Lightning damage investigation Material aging assessment Measuring phosphor content of Cu Alloys Monitoring of deposition process for non-ferrous material on a non-ferrous substrate Monitoring the condition of highly stressed parts Forged / plated material verification Non-conductive coating thickness measurement Determining the purity / composition of materials i.e. gold bullion and coins Aircraft structures e.g. Paint thickness measurement Assessment of aging of alloys Specifications ETher NDE SigmaCheck2 Specifications Conductivity Range 0.5% IACS to 110% IACS, 0.28 – 64 MS/m Operating Frequencies 60kHz, 120kHz, 240kHz, 480kHz. Option of 960kHz Accuracy Probe must be in thermal equilibrium with test material and instrument and probe stabilized prior to testing. Minimum 15-minute warm up time for stabilization At 68°F / 20°C: 0 – 20% IACS: ± 0.05 IACS At 68°F / 20°C: >20% IACS ± 0.25% of readout Display Resolution Up to 3 decimal places Lift Off 13mm probe compensated to 0.020″ (0.5mm); 8mm probe compensated to 0.010″ (0.25mm) Temperature Measurement In-probe sensor (accurate to 32.9°F / 0.5°C) Range 32°F – 122°F / 0°C – 50°C Automatic Temperature Compensation Conductivity measurements are corrected to the 68°F / 20°C value Environmental Range 0 to 95% relative humidity, 32°F – 122°F / 0° – 50°C for reliable operation Display 2.8″ (70mm), 320 x 240 pixels color display.
