Why people pick it

  • One kit covers both non-contact checks (12 to 1000 V AC) and contact voltage checks at eight labeled AC and DC levels, per Klein's spec
  • The NCVT-3P pen is IP67 dustproof and waterproof with a CAT IV 1000V rating
  • The ET45 needs no batteries; it is powered by the voltage it measures

Know before you buy

  • Klein says the NCVT-3P is not the recommended tool for tamper-resistant outlets (it suggests NCVT-2P or NCVT-3P in low-voltage mode there, and the ET45 lead holder for those outlets)
  • The ET45 reads level-indicator bands rather than an exact number
  • No display of measured voltage as a numeric reading on either tool
