Product Description
HI70031P Conductivity Calibration Standard – 1413 µS/cm (25 x 20mL Sachets)Premium NIST-traceable conductivity calibration solution standardized at 1,413 µS/cm for accurate calibration of EC meters, TDS testers, and conductivity instruments. Each box contains 25 single-use sachets ideal for hydroponics, aquaponics, water quality testing, and laboratory applications.Why Choose HI70031P Calibration Standard?
NIST traceable accuracy – Standardized with conductivity meters calibrated against potassium chloride NIST 2202 SRM (Standard Reference Material) for certified precision
Laboratory-grade preparation – Formulated with deionized water per ISO 3696/BS3978 standards using certified weight-checked balances, Class A glassware, and certified thermometers
Temperature compensation chart – Each sachet includes a printed chart showing actual µS/cm values at various temperatures for precise calibration
Single-use convenience – Pre-measured 20mL sachets eliminate contamination risk and ensure fresh solution every time
Light-block foil packaging – UV-resistant packaging prevents oxidation and value drift, maintaining solution integrity
Extended shelf life – Unopened sachets remain stable for up to 5 years from manufacture date
Portable design – Compact, lightweight sachets perfect for field testing and on-site calibration
Full traceability – Each sachet marked with lot number and expiration date for quality assurance and compliance

ApplicationsEssential for calibrating EC meters, TDS testers, and conductivity instruments used in hydroponics nutrient monitoring, aquaponics systems, greenhouse water quality, aquarium testing, pool and spa maintenance, drinking water analysis, wastewater treatment, environmental monitoring, and laboratory conductivity measurements. The 1413 µS/cm standard is the most common mid-range calibration point for EC meters.Why Single-Use Sachets?
Ideal for infrequent calibration – No waste from opened bottles that degrade over time
Perfect for field use – Portable and spill-resistant for on-site testing
Always fresh – Every sachet is as fresh as the day it was packaged
No contamination – Single-use format prevents cross-contamination between calibrations
UV protection – Light-block packaging prevents solution degradation from UV exposure
What's IncludedOne box containing 25 individually sealed 20mL sachets of HI70031P 1413 µS/cm conductivity calibration standard, each with temperature compensation chart, lot number, and expiration date.
