The Amprobe ACD-14 TRMS-PLUS clamp multimeter with dual display is the professional's choice for both
HVAC and electrical applications due to its complete set of measuring features. Thin jaws allow access
to tight measurement areas while still accommodating conductors up to 28 mm. The ACD-14 TRMS-PLUS's
dual displays allow for viewing amperage and voltage simultaneously. True RMS functionality enables
accurate readings in noisy environments.
The Amprobe ACD-14 TRMS-PLUS clamp multimeter measures AC & DC voltage to 600 V, AC current to 600 A,
capacitance to 3000 µF, Ohms to 40.00 MΩ, frequency to 600 F, and temperature from -4°F to 999°F with
a Type-K thermocouple probe. This Amprobe multimeter also measures DC & AC micro-amperage in the 400.0
µA and 2000 µA ranges. Other features of the ACD-14 TRMS-PLUS include continuity buzzer, diode test,
Hold and Maximum reading functions, auto power-off, and low battery indication.
The Amprobe ACD-14 TRMS-PLUS clamp multimeter ships complete with:
- Test leads
- Carrying case
- Bead-type thermocouple w/banana plug
- Manual
