NJTY T58C Digital Multimeter 9999 Counts Auto Range Inductance
NJTY T58B / T58C Professional Digital Multimeter — 9999 Counts, Auto Range
Meet the NJTY T58B and T58C — professional-grade digital multimeters built for electricians, engineers, hobbyists, and anyone who demands precision and ease of use in one rugged package. With 9999-count resolution, auto-ranging capability, and a host of smart features, these meters handle everything from basic voltage checks to advanced inductance and capacitance measurements with confidence.
Made in Mainland China.
Key Features
- Auto Range (9999 Counts): Automatically selects the correct measurement range, saving time and reducing errors — ideal for both beginners and seasoned professionals.
- Inductance Measurement (L): Shift the function dial to "L" and connect the probes to both ends of an inductor to read inductance values (10mH–100H) instantly — a capability rarely found at this price point.
- Smart AUTO Backlight Screen: The large HD display intelligently detects low-light environments and activates the backlight automatically — no button press needed. When voltage is dangerously high, the screen turns red as a clear visual alert.
- LED Flashing Jack Indicator: Color-coded LEDs flash around the correct input jack whenever you switch measurement modes. Perfect for beginners or anyone working fast in the field — no more guessing which jack to use.
- Dual Data Display: Shows 2 sets of readings simultaneously on the large screen, maximizing efficiency during complex electrical testing sessions.
- Built-in Spare Fuse Storage: A backup fuse is housed in the battery compartment on the rear of the unit — always at hand when you need a quick replacement.
- Protective Silicone Case: The shock-absorbing, dustproof silicone sleeve provides a comfortable, secure grip and protects the meter from drops and workplace wear.
- CE & RoHS Certified: Meets international safety and environmental compliance standards.

Frequently Asked Questions
Q: What is the difference between the NJTY T58B and T58C digital multimeters?
A: The T58B and T58C are functionally identical multimeters with the same 9999-count auto-range specifications. The only difference is color: the T58B comes in orange and the T58C comes in blue. Choose your preferred color when selecting your model.
Q: Does the NJTY T58C measure inductance, and how does it work?
A: Yes — inductance measurement is one of the standout features of the T58B/T58C. Simply rotate the function dial to the "L" position and connect the test probes to both ends of the inductor. The multimeter will display the inductance value across a range of 10mH to 100H.
Q: What does the LED Flashing Jack Indicator do?
A: The LED flashing jack indicator lights up around the correct input jack based on the currently selected measurement mode. This visual guide is especially helpful for beginners or professionals working quickly in low-light conditions, eliminating the risk of inserting probes into the wrong jack.
Q: Does the backlight turn on automatically?
A: Yes. The NJTY T58B/T58C features a smart auto-backlight that activates automatically when it detects a low-light environment — no need to press any extra buttons. The display also turns red when a high-voltage reading is detected as a safety alert.
Q: What batteries does the multimeter require?
A: The T58B/T58C requires 3 × 1.5V AAA batteries (not included). Batteries can be accessed by removing the battery cover on the rear of the unit, where a spare backup fuse is also stored for convenience.
