UN MÉTODO REPETIBLE
Cómo usarlo
- Choose tests for a specific question and check the range, expiry date and storage condition.
- Flush or disinfect the sampling point as required by the method and use a clean container.
- Follow the stated sample volume, contact time, temperature and color-reading window exactly.
- Run a blank, duplicate or known reference when the decision matters, and write down units.
- Confirm unexpected or health-relevant results through an accredited laboratory before changing treatment.
INTERPRETAR LA MEDICIÓN
Cómo interpretar el resultado
- TDS or conductivity indicates dissolved ions; a low number does not prove that water is safe.
- Hardness tests guide softener settings but do not measure iron, bacteria or organic contamination.
- Color strips are approximate and can be affected by lighting, timing, disinfectant and sample color.

Problemas comunes y qué comprobar
Problema
The electronic meter changes every time.
Qué hacer
Rinse the probe, remove bubbles, allow temperature compensation to settle and check calibration solution.
Problema
Strip colors sit between two chart values.
Qué hacer
Read under neutral light at the exact specified time and report a range rather than false precision.
Problema
Water looks clear but smell or taste changed.
Qué hacer
Stop relying on appearance and arrange targeted laboratory testing and a source inspection.
DETÉNGASE ANTES DEL PELIGRO
Límite de seguridad
- Do not drink water declared unsafe or under a boil advisory because a home strip looks normal.
- Handle reagents as labeled, keep them away from children and never mix test chemicals.
- Use a laboratory sampling kit for bacteria, metals and regulated drinking-water decisions.
GUÍA DE COMPRA INTELIGENTE
Qué buscar al elegir
- Buy tests matched to your source and treatment: hardness and iron for a softener are different questions from bacteria.
- Check detection range, expiry date, replacement reagents and calibration standards before buying.
- Prefer one reliable parameter-specific method over a large strip claiming many poorly resolved results.
Tipos de instrumento
Ideal para: Quick broad screening and deciding what to test properly.
Ideal para: Better hardness, alkalinity or disinfectant estimates.
Ideal para: Frequent trend checks with calibration and maintenance.
Ideal para: Health decisions, new wells and legal compliance.
