How compliant and universal is the 4 nm bandwidth Visible Spectrophotometer globally?
A: The 4 nm bandwidth fully complies with and covers the hardware requirements for optical resolution in international standards (US EPA, EN Standards, APHA) and fully complies with GLP (Good Laboratory Practice) requirements.
What are the key benefits of the localization of standard software (PC Software)?
A: Standard software upgrades the instrument from a simple "testing tool" to a "digital laboratory management terminal." Unlike international brands that require thousands of dollars extra for optional software, our standard software ensures your laboratory's procurement budget is met from the outset.
