Check Boxes

Check Boxes are specialist tools used to verify the accuracy and calibration of electrical test instruments.

Essential for electricians, inspectors, and maintenance engineers, they provide a safe and reliable reference point for confirming that testers are operating correctly before and after use.

Use cases include calibration checks on insulation testers, multifunction testers, and continuity meters.

The benefits include improved safety, compliance with BS 7671 and health and safety procedures, and reduced risk of inaccurate readings.
