Triplett 9055 3-3/4 Digit 4000 Count 6-in-1 Digital Multimeter CAT IV 600V

For technicians who need one reliable tool for field diagnostics, the Triplett 9055 digital multimeter delivers broad capability and rugged protection. This Triplett multimeter combines a precise 3-3/4 digit (4000 count) display with CAT IV 600V safety to give confidence when working on distribution panels, security and surveillance systems, or HVAC and electrical installations. With over 50 measurement ranges, the 9055 measures AC/DC voltage and current, capacitance, frequency, Type K temperature and ambient temp, plus environmental metrics like relative humidity, light (LUX) and sound (dBC) — reducing the number of instruments you need to carry.

Built for monitoring and maintenance workflows, the meter also includes NCV detection, continuity and diode tests to speed troubleshooting. The double-molded, splash-proof housing and integrated stand keep the meter secure on busy job sites, while Auto Power Off conserves battery life. Whether you’re validating CCTV power, commissioning HVAC sensors, or performing routine electrical testing, the Triplett 9055 streamlines diagnostics and improves uptime. Order the 9055 to equip your team with a versatile, safety-rated multimeter for professional security, surveillance and monitoring applications.

• Speed up troubleshooting across security, surveillance and electrical systems with a 3-3/4 digit (4000 count) display and 53 measurement ranges.
• Work safer on distribution-level installs: industry-leading CAT IV 600V protection reduces risk from transient overvoltages.
• Replace multiple tools — measures AC/DC voltage & current, capacitance, frequency, Type K temperature, relative humidity, light (LUX) and sound (dBC).
• Jobsite tough: double-molded, splash/dust and drop-resistant housing with built-in stand keeps the meter ready in harsh environments.
• Practical test aids include NCV, continuity and diode tests plus Auto Power Off to extend battery life during long shifts.
