## Description

Large Screen Multimeter - Volts Ohms Amps Transistor (hFE) Square Wave Output Diode & Audible Continuity Tester with Buzzer: desertcart.com: Tools & Home Improvement

Review: Nice lil meter - Bought it to play around with hardware hacking, and it works great for that purpose. Affordable and gets the job done.
Review: Good inexpensive way to measure hFE for gain matching your transistors - I needed a way to gain match a large batch of transistors but couldn't afford one of the expensive tools. This was perfect. The price didn't break the bank. The unit did a great job measuring hFE on all the transistors. I didn't test how well/accurate the rest of the functions are. I just needed it for hFE - awesome for that. Since it was really easy to use for my case, I remeasured all the components several times (needed to be precise). The measurements were consistent.

## Features

- Large 1.15in+ LCD Screen Digital Multimeter for easy to read on the go testing
- Custom Color Coded Symbols for Voltage, Amperage/Current, and Resistance are clearly labeled with their numeric values around the dial
- NPN & PNP Transistor Tester along with a Built in Buzzer for Audible Continuity Test
- Square Wave Signal, hFE Transistor, and Diode Function Testing are some of the advanced features included in this low cost solution
- Comes with an Illustrated User Guide, Test Leads, and Installed 9V Battery

## Questions & Answers

**Q: Anybody tried testing transistors?**
A: Yes, I have.   The hFE function measures the DC gain of the transistor when correctly inserted into the circular connector on the left of the multimeter.   You will notice the connector is split for NPN & PNP transistor gain testing respectively with connections for both the Base (B), Collector (C), and Emitter (E) of your transistor.  Be sure to properly insert your transistor leads all the way down on the correct side for NPN or PNP transistors as well as first identifying your transistors Base, Collector, and Emitter leads for proper testing. 

I just uploaded a picture on the listing page shows a transistor having it's hFE DC gain tested which is measured at 349.  This is normal for this transistor and shows it functioning properly.   Common transistor DC gain may be between 50-500, but this varies greatly transistor to transistor.

The picture is not live on Amazon yet, so in the meantime here is a link to it for reference:

**Q: How loud is the buzzer? Most multimeters have a tiny high-pitch sound that is nearly inaudible and useless to me.**
A: For the continuity test function on the multimeter the buzzer is audible fine for me, and I have never had issues hearing it or had any complaints about it.  Personally I find it very useful for circuit testing, but I have not used it in a very loud environment if that is what you are looking to do.  It would be hard to define without testing on a sound meter, but that said it is about the typical loudness of buzzers in similar multimeters due to the piezoelectric elements used to emit the sound.

**Q: Does this have a warranty?**
A: Hello!
Yes it does have a warranty against factory defects and workmanship for 90 days.  We at ProTechTrader stand by our products and are happy to help our customers with issues so do not hesitate to contact us directly at CS@ProTechTrader.com or through Amazon messaging system.

**Q: Am i able to tune this multimeter to "%hzv", select ac mode? i'm looking into a device that would require this to see if it's working properly.**
A: I just read the user manual... it is available with the listing.  This function is not available on this meter.

### ⭐⭐⭐⭐⭐ Nice lil meter
*by D***S on November 5, 2025*

### ⭐⭐⭐⭐⭐ Good inexpensive way to measure hFE for gain matching your transistors
*by M***L on October 16, 2023*

### ⭐⭐⭐⭐ Great value
*by G***R on August 19, 2023*

This small multimeter works well and is accurate (as compared to a Fluke). It has many features, such as transistor tester. The large digit display is a good feature. The test leads are short and the ends don't always make good contact. New leads are not expensive and these are standard banana type that can be easily replaced if needed.
