COP1PREFORM Portable Colorimeter for Plastic Preform Color Measurement and Quality Assurance
P1 Colorimeter for Preform Inspection – Accurate Desktop Preform Transmission Measurement
Precision Quality Control Tool for the Plastics Industry
The P1 preform inspection system is a high-precision, robust desktop instrument designed for measuring preform transmission values. Ideal for injection molding and quality control laboratories, it ensures early detection of transmission changes, reduces waste, and maintains consistent production quality. Its ease of use and stability make it suitable for both industrial and research environments.
Industrial Accuracy
- Measures preform light transmission from fully transparent to nearly opaque.
- Robust housing allows placement next to injection molding systems for real-time monitoring.
- Minimal operational errors due to simple 2-button interface and reflection chamber guides.
- Detects subtle transmission changes early to save time and reduce material waste.
- Can identify variations caused by preform position in the mold.
Application
This durable desktop instrument is designed for precise quality control of preform transmission, capable of measuring nearly opaque preforms down to 0.1% transmission.
Benefits
- Ensures consistent transmission quality for your customers
- Reduces errors from visual inspection caused by eye fatigue or operator changes
- Intuitive and simple operation
- Speeds up production adjustments between different preform transparencies
Easy Measurement (images 1-3)
- Place the preform in the center of the reflection chamber
- Lower the chamber over the preform
- Press the Measure button and read the transmission value on the LCD
Smart LED technology allows a wide dynamic range, measuring extremely dark preforms up to 99.9% transparent preforms.

Easy Calibration (image 4)
Calibration is simple: lower the reflection chamber without a preform and press the Calibration button. The instrument auto-calibrates to 100% and runs a lighting diagnostic. Functionality can be verified by measuring without a preform; the transmission value should read 100%.

Optional Windows Software
An Ethernet port allows connection to a network or PC for data logging. Transmission measurements can be recorded in a company database for reporting or historical review. An optional SDK is available, including protocol documentation and example C# source code for integration.
Rigorous quality assurance protocols in materials and plastics inspection workflows
Many facilities pair a preform transmission system with complementary colorimetric instrumentation like the SMART® 3 Colorimeter, which enables versatile, narrow band color analysis suitable for on‑site water and process monitoring. For broader spectral evaluation tasks where color difference metrics are critical, the Handheld Colorimeter delivers portable, repeatable ΔE*ab measurements for rapid assessment across diverse sample sets. In applications where specific analyte quantification remains a priority, the Chlorine Colorimeter Kit DC1500 offers a robust solution for chemical concentration evaluation in industrial and environmental testing scenarios.
