The HI7030L is a high-quality 12,880 μS/cm conductivity standard prepared in a NIST traceable potassium chloride solution. Hanna conductivity solutions come with a batch number and expiration date clearly marked on the label, and are airtight with a tamper-proof seal to ensure the quality of the solution.

Features:

• Temperature chart of the actual μS/cm value at various temperatures printed on each bottle
• Airtight bottle with a tamper-proof seal to ensure quality
• Size: 230mL
• Standardized with a conductivity meter calibrated with NIST 2202 SRM potassium chloride in deionized water for analytical use according to ISO 3696/BS3978 standard
