Heavy Duty DO, pH, and Conductivity Meters
What’s a Dissolved Oxygen (DO) Meter?
A Dissolved Oxygen (DO) meter both monitors as well as displays the oxygen concentration of liquids in mg/L and PPM. The Extech Heavy Duty DO Meter (407510) is inclusive of a KCL reference solution, membrane electrode (with 5 spares), user-calibration function, and temperature display (0 to 60°C). Moreover, an altitude compensation adjustment and Salt Water is provided.
Dissolved Oxygen Applications
DO measurements are utilized in applications where the amount of oxygen in a liquid has a critical effect on a manufacturing process or other environment. Wine production, fisheries, wastewater treatment, and environmental water quality are some of the relevant areas.
What is a Conductivity Meter?
A conductivity meter measures the ability of a solution to conduct electricity in units of cm/Siemen. The more conductive materials (like salts, metals, etc.) within a solution, the conductivity is higher.
Conductivity Measurement Applications
Conductivity measurements are utilized for streams, wells, and environmental tests in order to find out a pond’s health, pure water analysis, and other water bodies. Several manufacturing processes like PCB or component rinsing are also sensitive to the solution’s conductivity.
What is pH?
The term pH is utilized to define a system’s hydrogen-ion activity. The activity of this chemical enables us to find out, for instance, the alkalinity (8-14 pH) or the acidity (0-6 pH) of a solution (A pH of 7 is neutral). The Heavy Duty Model 407227 conducts measurements for temperature, mV, and pH. Temperature and pH probes are included within the kit version 407228. Dual display provides mV or pH and temperature indication. Automatic temperature compensation and calibration/slope adjustments are standard.
Applications for pH Measurements
For chemical processes, pH measurement is the most common. Applications include environmental analysis, food & beverage production, paper mills, pharmaceutical testing, wastewater treatment, and electro-plating. Anything consumed by animals and people, at some point, is tested for pH.
