Dilution Solutions HM Digital EC Calibration Solution - 1000 PPM - NaCl

1000 PPM NaCl Reference Standard for EC Meter Calibration

An EC meter drifts out of calibration over time, and without a trusted reference solution there is no way to confirm readings are still accurate. The Dilution Solutions HM Digital EC Calibration Solution provides a precise 1000 PPM NaCl (sodium chloride) reference standard, packaged in a reusable HDPE plastic bottle with a coated foam liner seal to keep the solution uncontaminated between calibration sessions.

This bottle format works with both ECO and PRO Dilution Solutions meter models, letting a single calibration solution cover multiple pieces of equipment in the same facility.

Key Features & Benefits

• 1000 PPM NaCl standard — precisely formulated sodium chloride solution for consistent, accurate EC meter calibration.
• HDPE plastic bottle — lightweight, durable, and chemical-resistant packaging for repeated use over time.
• Coated foam liner seal — protects solution purity and prevents contamination during storage and shipping.
• Compatible with ECO and PRO models — works with both Dilution Solutions meter product lines from a single bottle.
• Stable reference point — NaCl solution provides a well-characterized standard for repeatable conductivity measurements.

Who Should Use This

Hydroponic growers and greenhouse operators using HM Digital or Dilution Solutions ECO and PRO meters who need a reliable, reusable 1000 PPM NaCl calibration standard for routine meter maintenance are the direct fit.

Frequently Asked Questions

What PPM standard does this solution use?

This solution is a 1000 PPM NaCl (sodium chloride) calibration standard. It is formulated specifically for that reference point rather than a range of PPM values.

Which meter models is this compatible with?

This solution is compatible with Dilution Solutions ECO and PRO models as well as HM Digital EC meters. Confirm your specific meter model against the manufacturer's compatibility list if unsure.

Why use NaCl for EC calibration?

Sodium chloride solutions provide a stable, well-characterized conductivity reference that is widely used as a standard for EC meter calibration. That consistency is what makes repeatable meter readings possible over time.

How is solution purity maintained in this bottle?

The HDPE bottle with coated foam liner seal protects the solution from contamination and evaporation during storage. Reseal the bottle promptly after each use to maintain accuracy over its shelf life.
