Introduction

Water Quality Meter 850081 - Sper Scientific is a specialized multi-parameter measuring device suitable for testing drinking water quality, wastewater, and other industrial applications. The device allows measurement of important parameters such as pH, oxidation-reduction potential (ORP), conductivity, total dissolved solids (TDS), salinity, dissolved oxygen (DO), temperature, and oxygen concentration in air.

The meter is designed flexibly to work with various probes according to needs, helping save costs and accurately meet testing requirements. The LCD screen clearly displays parameters, integrates automatic temperature compensation and quick calibration features, supporting users for easy and accurate operation.

The product is officially imported from Sper Scientific, USA, ensuring high quality and durability, suitable for use in laboratories, water treatment plants, environmental monitoring stations, and other industrial fields.

Features

Supports multiple types of probes, enabling customized functions based on actual needs.
Multi-parameter measurement capability: pH, ORP, Conductivity, TDS, Salinity, DO, temperature, oxygen concentration in air.
Cost-saving by purchasing probes separately according to usage requirements.
LCD clearly displays measured values, with the top line showing main readings and the bottom line showing temperature (°C or °F).
Automatic temperature compensation for all measured parameters to improve accuracy.
Automatic calibration with standard pH buffer solutions 4, 7, 10.
Auto power off when not in use to save battery.
Hold function and display of maximum (Max) and minimum (Min) readings.
Design includes ¼” threaded hole for mounting on a stand (stand sold separately).
Probe not included in the package; users need to purchase probes separately as required.

Applications

The Water Quality Meter 850081 is suitable for use in water quality testing laboratories, clean water and wastewater treatment plants, environmental monitoring stations, food, pharmaceutical, and agricultural industries. The device helps users quickly assess important water parameters to ensure safety and efficiency in production and daily use.
