Buying Guide for Hvac Multimeters
If you are thinking that you can use any multimeter for hvac use then you are wrong, you must have a right multimeter with all hvac related functions and protections. Remaining qualities and consideration sould be same like other meters.
In hvac setups there is no space for breaks or trips, because after installation hvac system it becomes the only air source in buildings or factories we rely. So for smooth succesfull operation of hvac setups it should be maintained and monitored properly with help of a best accurate, precised multimeter.
There are many aspects to remember before purchasing a multimeter. Firstly it should be safety rated and protected against overloads. Durability and accuracy are also so much important for right selection .
As you know that electrical and electronics field is not a game of child, you have to look after complex circuits all the time with keen observation and monitoring. A best multimeter is best helper for electrical and hvac maintenance.
Without an accurate and reliable hvac multimeter hvac job could become so hectic for you. So we recommend you to choose wisely and don,t make a decision in hurry ever to avoid any inconvinience in future.
Now problem is how to check which is best hvac multimeter when there are hundreds of meters and dozens of brands available in market. Don,t worry we are here to solve your problems. We had generated a list of checks before selecting a multimeter for you.
Please read below for further details,
Safety is most important matter in multimeter selection, a multimeter should be properly designed according to safety standrads like UL and CE , IEC and CAT safety ratings.
You should first check in specifications whether your multimeter is overload protected, having fuse and all other safeties aswell. It would great if multimeter is laboratory tested and calibrated but you have to spend extra bucks for it.
Having right reading is so essential during hvac troubleshooting. Without accurate results it,s almost imposible to find faults in any electrical system.
So accuracy is also an imprtant thing to consider before making a purchase. Also keep in mind that mostly low budget multimeters are not precised enough to do tough troubleshooting tasks. You should be prepare to spend extra bucks for it.
Please note that the multimeters that are not calibrated in labs can give false readings. Most of the multimeters above 100 dollars are calibrated and tested.
For different applications needs you,ll need separate features in multimeters. For example if you want to buy a multimeter for only general household use like checking battery voltage level, main supply voltage, current drawn by electric appliances then you don,t have to buy expensive multimeters like fluke.
If you are going to select multimeters for industry or commercial level hvac systems, then you should must consider next level features like true rms, low impedance mode Loz, Min/max record, auto/manual raning, temperature measurements, UL certification and other usefull features.
Most of multimeters in low price has life upto 2 to 3 years if use and kept under good conditions. On other hand meters built with robust body materials like abs plastic may last upto 10 years or above with same accuracy and condition.
We strongly recommend to consider your work area environment and using habits before making purchase.
Offcourse budget is also an important factor to consider as all of us don,t have extra bucks to spend on expensive products. There is no need to panic if you are on low budget, many brands have standard multimeters in low price.
You can still get a best budget multimeter with same quality and features as some expensive one have, you just have to give some time to see specifications and read reviews in detail.
If you are purchasing multimeters for profesional use or industrial applications then we suggest to go only for high standard meters that are properly calibrated and precised neglecting whatever their price is.
