Description

The Amprobe AC75B is a digital clamp meter that measures AC current up to 600 A, AC voltage up to 750 V, DC voltage up to 1000 V and temperature up to 400°C (1000°F). Custom designed to make HVAC/R service, electrical and industrial maintenance tasks faster and easier. Amprobe AC75B digital clamp meters combine a heavy-duty high-capacity 600 A clamp-on meter with the most needed DMM functions such as resistance, continuity and voltage measurement for general electrical troubleshooting.

The Amprobe AC75B digital clamp meter goes above and beyond typical clamp meters and adds extra functions like a Type K digital thermometer, a high capacitance range and display backlight. The extra features of the AC75B enable more specialized troubleshooting such as measuring flame rod safeguard current and testing motor run/start capacitors. Amprobe AC75B digital clamp meters with temperature measurement have a CAT III 600 V and CAT II 1000 V safety rating.

The Amprobe AC75B digital clamp meter with temperature ships complete with:

  • Test leads
  • Temperature adapter (TA-1)
  • Type-K temperature probe (TP255A)
  • 9 V battery
  • Manual
  • Carrying case
