Elcometer 311 Automotive Paint Meter

Product Description

The Elcometer 311 Automotive Paint Meter is the fastest automotive paint gauge on the market today, used to instantly measure paint thickness and provide an indication of the overall condition of paint work.

With instant material recognition, the Elcometer 311 FNF Paint Meter switches between steel and aluminium panels and is ideal for use in all weather conditions.

The Elcometer 311 Automotive Paint Meter allows the user to quickly identify vehicle’s damage not reported in public or commercial condition reports including:

    • hidden rework
    • vehicle impact damage
    • vehicle respray
    • filled body panels

Compatible with ElcoMaster® Software and ElcoMaster® Mobile App, individual paint thickness readings can be transferred via USB or Bluetooth® to PC or a mobile device for analysis and instant report generation.

Features and benefits of the Elcometer 311 paint gauge include

    • Fast reading rate of 60+ readings per minute significantly reduces inspection times.
    • Switches instantly to measure coatings on steel & aluminium1
    • Ergonomic design gives you maximum comfort when measuring vehicles all day.
    • Automatic temperature compensation accurately measures in desert or alpine conditions alike.
    • Wirelessly connect the Elcometer 311 via Bluetooth® to your own inspection app or ElcoMaster® for seamless reporting2
    • Automatic rotating display allows you to read the thickness value on horizontal & vertical surfaces.
    • Ambient light sensor automatically adjusts the screen brightness to your lighting condition.
    • Dust & waterproof rugged design equivalent to IP64, ideal for measuring in wet or dry conditions.
    • Large easy to read values in mils & microns.
    • Scratch, solvent & water surfaces resistant colour display for protection against accidental damage.


“The Elcometer 311 doesn’t just take a thickness measurement”

In addition to the paint thickness, the Elcometer 311 Paint Meter displays the key statistical values used to assess the overall condition of the paint work; number of readings (n), average coating thickness (x), the lowest paint thickness (Lo) and the Elcometer Index Value (EIV).

Elcometer Index Value – EIV3

“The higher the EIV the more severe the PPW”

The Elcometer Index Value (EIV) provides the inspector with a single number which illustrates the vehicle’s overall paint condition and establishes any previous paint work (PPW) which has been undertaken. This quantifiable number determines the extent of rework & the overall quality of the vehicle being appraised.

Wireless Connectivity2

“Seamlessly connect to any PC, Android™ or iOS mobile device”  

As each measurement is taken, the Elcometer 311 Automotive Paint Meter can transmit the thickness value via Bluetooth® either straight into your inspection application or into ElcoMaster®, Elcometer’s mobile app, for instant report generation.

2 Year Warranty**

“Each gauge is designed to last”

Robust, durable & weather resistant, the Elcometer 311 is available with a 2 year manufacturer’s warranty; giving you a peace of mind.

Instruction Manual



The Elcometer 311 Automotive Paint Meter – detect hidden bodywork damage easier and faster using this ergonomic paint thickness gauge.

By measuring the vehicle paint thickness, the Elcometer 311 Paint Meter identifies hidden damage on a vehicle, which is often not found in public or commercial condition reports.

Using an Elcometer 311 Paint Meter in a pre-purchase inspection allows you to quickly identify hidden rework, impact damage, respray and filled body panels, which can all affect a car’s resale value.

The Elcometer 311 Auto Paint Meter is more advanced and easier to use than ever before. Unlike other gauges the Elcometer 311 Paint Meter displays key statistical values used to assess the overall condition of the paint work – it also has the unique Elcometer Index Value.

The Elcometer Index Value provides inspectors with a single number which illustrates the vehicle’s overall paint condition and establishes if any previous paint work has been undertaken. The higher the Elcometer Index Value the more severe the previous paintwork condition.

And if you are working with your own inspection app, the new Elcometer 311 has Bluetooth® – allowing all the measurements to seamlessly pass to your Android™ or Apple® mobile device in real time.
