One of the best digital multimeters under $100 is the Extech Ex505, and rightly so. It’s durable and gives exact and accurate readings making it the perfect tool for people who work with HVAC devices daily. Though not a complicated gadget, if you are not experienced, you might miss out on many of its features which mean you would be overpaying if you purchase it without first understanding what these features entail. To ensure that you get value for your money, let’s take a look at the key features of the Extech Ex505.

True RMS

This is a feature aimed at dealing with the problem of ghost voltage, especially if you are an electrician working under extremely unfavourable conditions. Thanks to this feature, you can get accurate voltage readings without the interference of ghost voltage. 

Data hold

There is nothing as problematic as trying to memorise meter readings, especially if you are working in an environment where you can’t comfortably write on paper and work at the same time. Through its data hold feature, the Extech Ex505 helps you by keeping a record of the last meter reading that you have measured. It only disappears once you read in a new figure, making this device very convenient to use.

Auto power off

One of the greatest costs that you can incur when using a multimeter is having to buy new batteries now and then. With the Extech Ex505, you will never have to deal with this problem. That’s because it has an auto power off feature that shuts the device down once it is inactive for more than 15 minutes. This feature can come in handy when you are working in an environment where getting new batteries is a hassle. 

The display

Most multimeters are hard to work with in dark areas because their screens do not have a backlight. Working under such conditions is not a problem if you have the Extech Ex505. It has a large 4000-count display that has LED backlights. This means it can comfortably be used at night or in dark arrays.

The design

Multimeters are made to be carried around all the time and to be put to work in environments where they can accidentally fall. That’s why it’s best to have a light multimeter that’s also made of durable materials. These two factors are part of the Extech Ex505’s design. It is made of light, sturdy materials and also has a protective rubber casing. Its design also incorporates a waterproof housing making it ideal for work under all conditions.

Temperature measurements

The Extech Ex505 measures temperatures using a thermocouple. This means you can easily measure temperatures by placing it on the object’s whose temperatures you want to measure. You can also submerge it, in case you measure a liquids’ temperature. 

Do we recommend the Extech Ex505, definitely yes. Read our full review for more details.
