Product catalog summary
Introduction
The SigmaCheck 2 Eddy Current Conductivity Meter is designed for accurate conductivity measurements, offering reliability, usability, and cost-effectiveness. It is suitable for various industries including aerospace, metals processing, and quality assurance.

Applications
The device is used for material verification, heat treatment verification, damage investigation, material ageing assessment, and more. It can measure non-conductive coating thickness and determine material purity.

Compliance
The SigmaCheck 2 complies with several inspection procedures such as Boeing BAC5651, Airbus AITM 6-6004, ASTM E1004, and others.

Specifications
- Dimensions: 168mm x 85mm x 30mm with rubber boot.
- USB connection for PC link and charging.
- High-resolution color display.
- Conductivity range: 0.5% IACS to 110% IACS.
- Operating frequencies: 60kHz to 480kHz, with an option for 960kHz.
- Lightweight and ergonomic design.

Advantages
- User-programmable display and data storage.
- Multiple language support.
- Real-time PC control via USB.
- Firmware upgradable in the field.

Key Features
- High-resolution display with customizable settings.
- Rapid display of conductivity results.
- Excellent data reporting and battery life.
- Field exchangeable probes.

Understanding Conductivity
Conductivity measures a material's ability to conduct electric current, inversely related to resistivity. The SigmaCheck 2 uses a three-point reference method for accurate readings.

Technical Specifications
- Conductivity range: 0.5% IACS to 110% IACS.
- Accuracy: Requires thermal equilibrium and stabilization.
- Display resolution: Up to 3 decimal places.
- Temperature measurement: In-probe sensor, range 0°C to +50°C.
- Environmental range: 0 to 95% relative humidity, 0°C to +50°C.
- Power: 2 x 1.5 V AA NiMH Batteries, up to 9 hours life.

Accessories
Includes calibration blocks, probes, and optional extras like a rugged transit case and small probe.

Understanding Conductivity Ohms Law Equation: I = Current (Amps) Conductivity is widely used to indicate material type and determine the state of heat treatment. V = Voltage (Volts) R = Resistivity (ohms) Electrical Conductivity Equation: O~= R = O"A l = length (cm) A = Area (cm2) R = Electrical Resistance of a uniform specimen of the material (ohms) O“ = Conductivity (ohm-1 cm-1) In order to give accurate readings the SigmaCheck 2 uses a three-point reference method. The first measurement with the probe in the air and then two further measurements are required which span the range of interest....
