Veribox VB2 resistance box

Warmbier Veribox VB2 is a precise and reliable reference tool designed to verify high-resistance meters and ESD test instruments before use. It features three accurately defined resistance values – 10 kΩ (±0.1%), 1 MΩ (±0.1%) and 1 GΩ (±2%) – covering the full range of typical ESD and high-resistance applications and enabling accurate checks across multiple measurement decades. The unit is completely passive and requires no power supply, eliminating maintenance and the risk of measurement errors caused by weak batteries. Its insulating plastic housing ensures safe operation in production environments, calibration labs and service applications. The VB2 integrates easily into quality assurance and ESD control programs, with a recommended calibration interval of three years.
