FAQ

What are the main applications of the Portable Multi Parameter Water Quality Meter?

The Portable Multi Parameter Water Quality Meter is used to determine water-quality parameters such as oxygen demand, carbon, nutrients or chlorine. It supports environmental monitoring, wastewater plants, drinking water, laboratories and industrial discharge checks.

Which standards and regulations apply to the Portable Multi Parameter Water Quality Meter?

The analyzer is designed with reference to applicable ISO, EPA-equivalent and GB/T water-quality methods and IEC 61010 electrical safety. Reagents and procedures must follow the named method. Compliance documentation can be provided on request.

What warranty comes with the Portable Multi Parameter Water Quality Meter?

A 12-month warranty applies to the complete equipment against defects in materials and workmanship. It excludes consumables, wearing components and accidental or misuse damage. Our service team handles claims against the serial number, and longer cover can be arranged.

Is the Portable Multi Parameter Water Quality Meter difficult to operate?

The controls are designed for regular laboratory use, so most users become confident after a brief introduction. The manual walks through each step, and common settings can be saved for repeat work. Online or on-site training is available if the site requires it.

What is the typical lead time for order delivery?

Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.

How often should the Portable Multi Parameter Water Quality Meter be calibrated?

Factory calibration is included, and routine verification is recommended every 6 to 12 months using suitable reference materials. Regulated sites may require more frequent checks and documented records. Calibration support and certificates can be provided on request.

Are the consumables universal or proprietary?

The instrument uses standard, widely available consumables rather than special locked items. Replacement parts, accessories and consumables can be ordered from us against the model number. We keep common service parts in stock for prompt supply.

Can it be adapted to our requirements?

The standard model can be configured with selected accessories and operating options to suit the task. Non-standard requests are assessed before quotation so the final build is clearly defined. We confirm details before production.

Do you provide on-site installation?

The unit is delivered ready for set-up, with clear commissioning steps in the manual. We provide remote technical support during installation. For larger or regulated systems, a factory-trained engineer can attend on site on request.

What maintenance and safety points matter?

Do not use expired reagents, unrepresentative samples or skip blanks and standards. Preserve samples as required and handle reagents safely. Follow laboratory safety rules.
