Purpose: The ColorFlex EZ sample view area measures 25mm (1.0in) in diameter with a 32mm (1.25in) open port (HL# 04-6623-10). Reading an area smaller than the normal fixed view of the ColorFlex EZ means that the port is masking the viewed sample area by the sensor.
Hunter Lab has 3 smaller diameter ports that allow measurements of samples smaller than 32mm and these ports mask the viewed area of the sensor. Standardization minimizes the masking effects. but the limit is typically a diameter half of the normal view (13mm or 0.50 in in this case).
Here are some open, masked port options that can be used with the ColorFlex EZ or legacy ColorFlex 45/0 LAV:
04-6623-09 Open Port Insert, 25mm (1.00in), Masking- Provides a field-replaceable, snap-in 25mm (1.00in) port insert that is open and masks the sample to the 25mm viewing area of the instrument.
04-6623-08 Open Port Insert, 19mm (0.75in), Masking - Provides a field-replaceable, snap-in 19mm (0.75in) port insert that is open. The instrument typically measures a 25mm viewing area and this port masks the viewing area of the sample to a smaller 19mm diameter.
04-6623-05 Open Port Insert, 13mm (0.50in), Masking - Provides a field-replaceable, snap-in 13mm (0.50in) port insert that is open. The instrument typically measures a 25mm viewing area and this port masks the viewing area of the sample to a smaller 13mm diameter.
02-6624-01 Port Insert, 25mm (1.00in) with Glass, Masking Provides a field-replaceable, snap-in 25mm (1.00in) port insert with clear borosilicate glass. The 25mm diameter port masks the sample to the 25mm viewing area of the instrument. The glass is intended to protect the interior of the instrument from sample and airborne particles.
