Honeytek HK78B PRO – 4,000 Counts TRMS Manual Range Digital Multimeter

 Descrição do produto

The Honeytek HK78B PRO is a premium 4,000-count true RMS manual range digital multimeter with enhanced features for more demanding professional applications. While it shares the same core electrical measurement capabilities as the HK78A PRO, the HK78B PRO stands out with its expanded temperature measurement range. This makes it an ideal tool for technicians working with heating systems, engines, and other applications where a broad temperature range is required. Its combination of accuracy, safety features like NCV, and extra functionality make it a versatile and powerful diagnostic instrument.

Destaques

• 4,000 counts display for high-resolution measurements.

• RMS real for accurate AC signal analysis.

• Extended temperature range from -20°C to 1000°C (-4°F to 1832°F).

• Non-Contact Voltage (NCV) e reconhecimento de fios sob tensão for safety.

• Lanterna e LCD backlight for ease of use in dark spaces.

• Suspensão da recolha de dados e relative mode to simplify complex readings.

• CAT III 1000 V safety certified.
