The 3nh NH-A-1508 Powder Test Box manual explains how to assemble, calibrate, measure, and clean the box for use with 3nh NH series colorimeters.
The NH-A-1508 powder test box is an accessory for 3nh NH series computer colorimeters, designed to measure the color data of powders. It consists of four cover plates, a powder box, a lens, and an external pressure plate.
The manual provides step‑by‑step instructions: calibrate the white and black boards using the lens, load and compress the powder in the powder box, install the box and lens, perform the measurement, and finally clean and store the test box. This manual is written in Chinese.
Place the lens into the white board box and perform white‑board calibration, then follow the manual to perform black‑board calibration on the NH series colorimeter.
After measurement, clean the powder test box as needed, optionally using alcohol, then let it dry before storing.
