Customer Questions & Answers
-
Question:
What features does the Extech EX355 True RMS Professional MultiMeter offer?
Answer: The Extech EX355 MultiMeter includes True RMS measurements, non-contact voltage (NCV) detection, and temperature measurements. True RMS ensures accurate readings of both AC and DC voltages and currents, while NCV allows for quick voltage detection without physical contact. The temperature function includes K-type thermocouple support, letting you measure temperature from various surfaces. These functionalities make it ideal for electricians, technicians, and DIY enthusiasts who require precise measurements across multiple applications. -
Question:
How does the True RMS feature benefit my electrical measurements?
Answer: True RMS technology provides accurate measurements for both sinusoidal and non-sinusoidal waveforms, which is crucial when working with complex electrical systems. Unlike average-responding meters, True RMS meters like the EX355 ensure that you get correct voltage and current readings, regardless of waveform distortions. This accuracy is particularly vital when diagnosing issues in variable frequency drives or electronic loads, making the EX355 an excellent tool for professionals in electrical and HVAC fields. -
Question:
Can the Extech EX355 measure both AC and DC voltages?
Answer: Yes, the Extech EX355 is designed to measure both AC and DC voltages effectively. It has a wide range of voltage measurement capabilities, ensuring it can cater to various electrical tasks. This functionality is useful for professionals conducting field work or even home DIY projects, allowing for safe testing and diagnostics of different electrical systems without swapping between multiple devices. -
Question:
What is the maximum temperature the Extech EX355 can measure?
Answer: The Extech EX355 can measure temperatures ranging from -40°C to 1000°C (-40°F to 1832°F) when using a K-type thermocouple. This wide range allows versatility in application, from HVAC service and automotive diagnostics to general scientific experiments. Users can easily switch between temperature measurements for air, liquids, and solid surfaces, making it an invaluable instrument for various industries. -
Question:
What types of batteries does the EX355 use?
Answer: The Extech EX355 operates on a 9V battery, providing long-lasting power for extended use in various environments. It is designed for easy battery replacement, ensuring that you can conveniently continue your work without interruptions. This portable functionality is essential for technicians on-site who need reliable operational time while conducting tests in different settings. -
Question:
Is the Extech EX355 suitable for household use?
Answer: Absolutely! The Extech EX355 is user-friendly and ideal for household maintenance tasks, such as testing outlets, checking batteries, and troubleshooting appliances. Its NCV feature allows even novices to detect electrical issues without risk, making it a valuable tool for homeowners looking to tackle electrical projects safely and effectively. -
Question:
How do I utilize the non-contact voltage (NCV) feature?
Answer: Using the NCV feature on the Extech EX355 is straightforward: simply switch on the meter, hold it near any potential live wire or electrical source, and watch for the visual or audible indicator. This feature makes it convenient to check for live currents without physical contact, greatly enhancing safety during installations or repairs. It's especially helpful for electricians who need to quickly assess areas with high voltage concerns. -
Question:
Can the Extech EX355 perform continuity testing?
Answer: Yes, the Extech EX355 also has a continuity testing function that allows users to check for breaks in circuits or faulty connections. When testing continuity, the meter will emit a sound if a complete circuit is detected. This feature is particularly beneficial for electricians and DIYers who need to maintain or install electrical systems, ensuring everything is connected properly without the risk of injury. -
Question:
Is the EX355 equipped with data hold and backlight features?
Answer: Yes, the Extech EX355 comes with both a data hold function and a backlight feature. The data hold function saves your readings on the display, allowing you to capture measurements without needing to constantly look at the device. The backlight enhances usability in low-light positions, making it easier to read the display. These features are particularly useful during detailed inspections in dimly lit areas, providing an easier and more accurate assessment. -
Question:
Where can I buy the Extech EX355 True RMS Professional MultiMeter with NCV and Temperature Measurements in New Zealand?
Answer: You can purchase the Extech EX355 True RMS Professional MultiMeter with NCV and Temperature Measurements at Ubuy.

Extech Multi Testers Editorial Review
The Extech EX330 Autoranging Mini Multimeter is a great investment for hobbyists, homeowners and professionals. It has a lot of functions and is a great buy for the price. Though it takes some time to display correct readings, it appears to be very accurate with the delay not really impacting functionality. It is accurate, durable and easy to use. One reviewer said it is one of the best meters he has ever owned. Another said that it's an excellent value for a quality meter. However, the meter is very slow to process readings which makes it inconvenient for real life work situations, although it's fine for bench testing. The backlight is also not very user friendly. There is a defect in some pieces where it has a tendency to fry and melt the inside battery holder. In general, it is better suited for limited use and tight budgets.
