導電度標準液 Conductivity Standards
產品編號
Hach導電度(電導度)標準液皆可追溯至NIST(美國國家標準技術研究所). All standards are NIST traceable.

Hach電導率標準液有多種包裝尺寸可供選擇,從1公升瓶裝到適用於現場分析單次使用之20毫升單片。 單次使用之單片(singlets)確保新鮮度並消除污染的可能性。

Hach conductivity standards are available in a variety of packaging sizes - from bulk 20 L containers down to single-use 20-mL Singlets for on-site analysis. Singlets assure freshness and eliminate the possibility of contamination.

For all Hach conductivity standard, a specific Certificate of Analysis is available for download from www.hach.com: Support/Service, Certificate of Analysis menu using product part number and lot number.
