Educational Benefits & Features
Feature: Hermetically sealed internal scale.
Benefit: Solves the problem of scale degradation; unlike external etchings that fade when exposed to fuming Hydrochloric Acid or Nitric Acid, the enclosed markings remain permanently legible.
Feature: Borosilicate glass outer sleeve.
Benefit: Provides superior resistance to thermal expansion and mechanical shock, reducing the frequency of breakage during student-led thermodynamics experiments.
Feature: High-contrast background strip.
Benefit: Improves reading accuracy by providing a sharp visual contrast against the sensing liquid, minimizing parallax error during critical data logging.
Feature: Mercury-free sensing variants.
Benefit: Addresses institutional safety requirements for younger age groups by utilizing non-toxic spirit filling, ensuring a safe laboratory environment without sacrificing thermal sensitivity.
Feature: Precision-engineered capillary.
Benefit: Ensures linear expansion of the sensing medium, providing students with repeatable and reliable data points for calculating specific heat capacity or latent heat.
Curriculum Alignment
This instrument is designed to meet the rigorous laboratory infrastructure requirements for STEM, TVET, and Next Generation Science Standards (NGSS). It specifically supports benchmarks in Physical Science related to "Matter and its Interactions" and "Energy," where students must observe phase changes and thermal equilibrium in various chemical mediums.
