Hanna TDS Calibration Solution HI7032L 1382 mg/L (ppm), 500mL

The Hanna TDS Calibration Solution HI7032L 1382 mg/L (ppm), 500mL is a high-quality calibration standard designed to calibrate and verify Total Dissolved Solids (TDS) meters. It provides a defined reference value of 1,382 mg/L (ppm) at 25°C, helping users maintain reliable and consistent TDS measurement performance in laboratory, water quality testing, and industrial applications.

TDS measurement is widely used to estimate the concentration of dissolved substances in water. Accurate measurements depend on proper instrument calibration with a suitable standard solution. HI7032L is prepared against a potassium chloride solution traceable to the National Institute of Standards and Technology (NIST), supporting dependable calibration practices.

The solution is supplied in a 500mL bottle designed with an airtight closure and tamper-proof seal. Each bottle is marked with a lot number and expiration date to help users identify the product and monitor its validity. According to the manufacturer, an unopened bottle has a shelf life of five years from the date of manufacture when stored as directed.

How to Use the Calibration Solution

Before calibration, check the TDS meter’s operating manual to confirm that the instrument supports a 1,382 mg/L (ppm) calibration standard.Hanna TDS Calibration Solution

1. Pour a sufficient amount of fresh calibration solution into a clean container.
2. Rinse the meter’s probe with purified water and gently remove excess water.
3. Immerse the probe in the solution according to the instrument instructions.
4. Allow the reading to stabilize and complete calibration using the meter’s specified procedure.
5. Dispose of used solution appropriately. Do not return used solution to the original bottle.

For reliable results, avoid contaminating the bottle or calibration solution. Use fresh solution for each calibration whenever possible, and follow the instrument manufacturer’s recommendations for calibration frequency.Hanna TDS Calibration Solution

Storage and Handling

Keep the bottle tightly closed when not in use. Store it according to the label and manufacturer’s instructions, and avoid contamination from samples, rinsing water, or other chemicals. Check the lot number and expiration date before use. Do not use contaminated or expired solution for accuracy-critical measurements.Hanna TDS Calibration Solution
