Hanna HI7031L 1413 µS/cm Conductivity Calibration Solution – 500 mL

The Hanna HI7031L is the most universally utilized Electrical Conductivity (EC) calibration standard in the world. Formulated to exactly 1413 µS/cm (1.41 mS/cm) @ 25°C, it is housed in a UV-blocking 500 mL bottle. Traceable to NIST standards, it is the mandatory daily calibration fluid for general laboratory analysis, hydroponic nutrient mixing, and commercial agricultural diagnostics.

Set the absolute standard in your daily operations with the Hanna HI7031L 1413 µS/cm EC Calibration Solution. If you own an Electrical Conductivity meter—whether it's a premium edge® multiparameter benchtop in a university lab, or a waterproof pHep® pocket tester on a hydroponic farm in Punjab—the 1413 µS/cm (1.41 mS/cm) value is the most common calibration point required by the internal software.

The HI7031L is the daily workhorse of the analytical world. It ensures your probes are measuring dissolved minerals, fertilizers, and general water hardness with undeniable accuracy. Hanna produces this critical standard using ultra-pure Potassium Chloride in a highly sterile environment. Packaged in a 500 mL Light-Block Bottle with an air-tight, tamper-evident seal, it provides hundreds of highly stable calibrations, drastically extending the life of your expensive electronic meters.

• Universal Application: Ideal for general laboratory testing, drinking water hardness analysis, and commercial greenhouse fertigation.
• UV & Air Protected: The FDA-compliant 500 mL bottle protects the fluid from environmental degradation, ensuring a long, stable shelf life.
• NIST Traceable: Provides the verifiable chemical accuracy required to pass quality control audits.

Frequently Asked Questions (FAQs):

Q: What is the price of the Hanna HI7031L in Pakistan?

A: Visit Kamadi.pk for current pricing. We offer Cash on Delivery to all major cities, making it easy for independent contractors and farmers to restock.

Q: Will this calibrate my TDS meter?

A: Yes. If your TDS meter uses the standard 0.5 conversion factor (1413 µS/cm = 706 ppm), calibrating the EC automatically calibrates the TDS reading.

Q: Do I need to clean my probe before calibrating?

A: Absolutely. Always rinse your probe in distilled or deionized water before dipping it into the beaker of HI7031L; otherwise, you will contaminate the reading.
