The Light Reflectance Value (LRV) measurement of a material surface is on a scale from 0% BLACK to 100% for WHITE. If a material is measured 9 times then averaged the LRV number may be referenced to your BS 8493. The meter can auto-average for you.

It’s quick and easy:
- Displays the measurement fast
- Measures the material surface in seconds
- Used by building materials and product designers, and architects
- Check LRV specifications!

This CROMOCON LRV METER APP runs the CROMOCON LRV METER. It provides the LRV measurements used to calculate the CONTRAST between two adjacent surfaces - like paving and a wall, or a wall and a door for example; so visually impaired people can experience environments safely. CONTRAST ensures that an object, element, or text in signage for example is VISIBLE or NOT VISIBLE to 93% of visually impaired people (VIP).


Allows the phone user auto-renewals when alerted to upgrades. Meter users get assistance measuring with the meter.
