The TLV-304-LC is a compact transmittance meter with a correction filter
which approximates to the luminosity curve. This unit quickly
measures the transmittance with a value close to sensitivity of human
eyes and allows easy measurement by placing a sample after one-touch
calibration. It is suitable for a quick inspection process to conduct large
volume of measurements.
