Lamotte ISO Turbidity Standard 10 NTU 1454 60mL Calibration Solution

Description

Product Overview

The Lamotte ISO Turbidity Standard 10 NTU (model 1454) is a high‑purity, liquid calibration standard formulated to deliver a consistent turbidity level of exactly ten Nephelometric Turbidity Units (NTU). Packaged in a 60 mL amber glass vial, the solution is protected from light and contamination, preserving its stability over extended storage periods. The formulation complies with ISO 7027‑1 specifications, making it an ideal reference material for both laboratory‑grade turbidity meters and portable field instruments. Its low viscosity and clear appearance ensure easy handling, while the precise concentration supports repeatable measurements across a wide range of water‑quality testing scenarios.

Usage

Designed for water‑treatment facilities, environmental monitoring agencies, and research laboratories, this standard is used to verify and calibrate turbidity meters before routine testing. Users simply pour the 60 mL solution into the sample cell of the instrument, allowing the device to read the known 10 NTU value. The standard is compatible with all LaMotte turbidity meters, including handheld models and benchtop analyzers, as well as third‑party instruments that accept liquid standards. Routine calibration with this solution helps maintain measurement accuracy, supports compliance with regulatory limits, and reduces the risk of false‑positive or false‑negative results in critical water‑quality assessments.

FAQ

How often should I calibrate my turbidity meter with this standard?

Calibration frequency depends on the instrument’s usage and the criticality of the measurements. For routine laboratory work, calibrate at least once a week or after any maintenance event. Field users should calibrate before each sampling campaign or whenever the meter has been exposed to extreme temperatures.

Can I store the standard at room temperature?

Yes. The amber vial protects the solution from light, and the formulation remains stable at typical indoor temperatures (15‑25 °C) for up to 12 months. For longer storage, keep the vial in a cool, dry place away from direct sunlight.

Is this standard compatible with non‑LaMotte turbidity meters?

Absolutely. The liquid format and 10 NTU concentration are universally recognized, so any turbidity meter that accepts liquid standards can be calibrated with this product. Always refer to the instrument’s user manual for specific sample‑cell requirements.

What should I do if the measured value deviates from 10 NTU?

If the instrument reads outside the acceptable tolerance (±0.5 NTU), first verify that the vial is properly sealed and that no air bubbles are present in the sample cell. Re‑mix the solution gently, re‑measure, and if the discrepancy persists, consult the troubleshooting guide or contact Lamotte technical support for assistance.

Does the product include a certificate of analysis?

Yes. Each package is accompanied by a Certificate of Analysis (CoA) that documents the exact turbidity value, temperature of measurement, and traceability to ISO standards, providing the documentation required for regulatory compliance.
