❓ Frequently Asked Questions (FAQ)

Q: What is the difference between single beam and double beam?
A: Double beam design splits the light into reference and sample paths, compensating for light source fluctuations and detector drift. It offers more stable baseline and better repeatability for long-running measurements.

Q: What cuvettes are included?
A: Standard package includes 4 pcs glass cuvettes (1 cm) and 2 pcs quartz cuvettes (1 cm). More cuvettes of various path lengths are available on request.

Q: Does it come with software?
A: The instrument runs on its 8-inch touch screen without PC. Optional UV WIN8 software is available for full-spectrum scanning, data processing and report generation on Windows PC.

Q: What is the minimum order quantity?
A: One unit.

Q: What is the lead time?
A: Approximately 30 days (factory lead time, excluding international shipping time). Exact time is confirmed at quotation according to configuration.

Q: What are your payment terms?
A: Payment is 100% T/T in advance.

Q: Do you provide installation support?
A: Yes. Remote video installation and debugging are provided. Engineers guide you online from unboxing to ignition testing.

Q: What is the warranty?
A: One year warranty. Lifetime technical support.
