Temperature Measurement and Calibration. Temperature Measurement and Calibration
A bench top unit comprising a
hypsometer /hot water bath and ice flask which generate accurate fixed
points and variable temperatures
An accurate platinum resistance
thermometer with five point calibration certificate and temperature
indicated directly in °C is included for reference.
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 with calibration supplied
All electrical sensors can be logged using a PC (optional teaching software available)
Description:
A benchtop unit designed to introduce
students to temperature, temperature scales and commonly available
devices to measure temperature. The equpment comprises a hypsometer/hot
water bath and ice flask to generate accurate fixed points (the
condensation point and triple point of water) and variable
temperatures. Temperature sensors having different thermometric
principles and characteristics are supplied. An accurate platinum
resistance thermometer with five point calibration certificate 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 steam tables, provided that an accurate
barometer (not supplied) is available. 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 allows all sensors to be transferred simultaneously from ice
flask to the hypsometer/water bath
