Description

A bench top unit designed to introduce students to temperature, temperature scales and commonly available devices to measure
temperature.
The equipment comprises a hypsometer/hot water bath and ice ?ask to generate accurate fxed points (the condensation point and triple point
of water) and variable temperatures.
Temperature sensors with di?erent thermometric principles and characteristics are supplied. An accurate platinum resistance
thermometer (PT100) with fve point NAMAS calibration certifcate and temperature indicated directly in °C, is included for reference.
The temperature of the condensing water vapour in the hypsometer can be determined accurately using the software or tables in the
manual, providing knowledge of the barometric pressure is known.
The water level is simply raised to change the hypsometer into a variable temperature water bath.
The unit is designed for safe operation with insulation surrounding the vessel and a protected steam vent. A radiation shield surrounds the
sensors to be calibrated to minimise measurement errors. A common carrier enables all sensors to be transferred simultaneously from ice ?ask
to the hypsometer/water bath.
All thermometric properties and temperatures measured are displayed on a digital meter with selector switch.
All important electronic sensors used on the unit provide outputs for data logging and analysis. The data logger, provided with the unit,
interfaces between the unit and the user’s computer using a USB port.
The optional educational software package enables data recording, graph plotting and provides full instructions for setting up equipment
and performing the experiments.
All related theory and help texts are provided. The software requires a computer (not supplied) running Windows 7 or later with a USB port.

Key Features

• Thermometric properties (physical changes due to temperature)of different sensors are investigated
• Condensing vapour (using a hypsometer) provides an accurate fixed point for calibration
•  Stirred hot water bath provides variable temperatures
  
•  Reference Platinum Resistance Thermometer (PRT) with NAMAS calibration supplied
  
• All electrical sensors can be logged using a PC (not supplied). Optional teaching software is available for data logging
