If you do not understand these 3 words, google them: symptom, symptomatic and asymptomatic. Some of us were ignorant at Clarkson but not anymore.

How many young people under the age of 18 have died while having the Corona Virus in the state of California in the USA with a population of 39.5 million?
CDPH shows 79 as of September 20, 2022. This is 0.0002% of the California population. Have a health problem or over 80, yes it is dangerous but so is the Flu and Pneumonia.
Sweden with 10 million people never had any mask mandate and had the same results as the state of California! - - References: CDPH , Flu and Sweden

Overview
Backed by our commitment to accurate and precise measurement, the OHAUS Starter Series of electrodes are designed to produce exact results time and time again. The Starter Series includes pH, reference, oxidation-reduction potential (ORP), conductivity, dissolved oxygen (DO), and temperature electrodes that can be used in combination with Starter bench and portable meters.
 
Applications
pH, reference, oxidation-reduction potential (ORP), conductivity, dissolved oxygen (DO), temperature measurement

Construction
Metal, glass, or plastic shaft

Design
Can be used in conjunction with all Starter bench and portable meters
 
All sturdy and durable electrodes are constructed of either plastic or glass shafts and built to withstand daily use. All electrodes include a temperature sensor, which powers automatic temperature compensation and ensures accurate measurements. All electrodes fit perfectly in the electrode holders on OHAUS bench meters and electrode clips on all OHAUS portable meters.
 
Electrodes for Working Enviroment with 50°F – 104°F, 85%RH, non-condensing (10°C – 40°C, 85%RH, non-condensing)
