A pH-meter capable of measuring conductivity and dissolved oxygen at the same time is composed of a gauge and three probes. Three power sources and three measuring circuits are mounted to the gauge. The detectors of the probes include a pH detector, a conductivity detector and a dissolved ...
Photo: How do you measure the pH of soils on Mars? Simple! You build a pH meter into a robotic space probe. The Mars Phoenix Lander space probe (left) used this built-in, mini chemical laboratory (right) to measure different aspects of the Martian soil, including acidity and metal ...

Then, the electrical conductivity of the refined aqueous ammonia with the concentration of ammonia unknown is measured with a conductivity meter and as necessary, the pH is further measured with a pH meter. Resulting measured values are substituted into the expressions for the relation, to determine...

The meter must be calibrated regularly (e.g. using a two-point calibration of 0 and 100% air saturated water). Liquid water For properties of rooting medium and/or irrigation water: •• Dissolved oxygen meter (see "Dissolved oxygen"). •• Electrical conductivity (EC) meter:...
A method for monitoring the misalignment of the magnetic axis in solenoids is proposed. This method requires only a few measurements of the magnetic field at fixed positions inside the magnet aperture, and thus overcomes the main drawback of sturdy movin
