Ammonia, nitrate, nitrite, pH and water hardness was monitored twice a week using commercial kit (Tetra GmbH).
The coatings were characterized by scanning electron microscopy, optical microscopy, X-ray diffraction, roughness, porosity, hardness and by monitoring mechanical behaviour of samples in tensile test submitted to previous and simultaneous hydrogen charging.
When accounting for DBH measurements and average wood density per wood hardness class, experienced monitors performed better and generated lower bias compared to their inexperienced counterparts (Figure 5, Estimates 1).

A new instrumented penetration test has been developed which continuously monitors the hardness development during early hydration and enables greater understanding of details of the hardening process.
In this work, we used a dynamic approach, referred as continuous stiffness measurement (CSM) mode [12], to continuously monitor the hardness and Young's modulus values as a function of the indentation depth.
Herein, in this study, a continuous stiffness measurement (CSM) mode [15] was adopted to continuously monitor the hardness and Young's modulus values of BFO films as a function of the indentation depth.

You are not hard for hardness's sake.
Temperature, pH, conductivity, dissolved oxygen concentration and hardness of test water were also monitored throughout the study.
