Temperature Measurement and Calibration Apparatus
Product Code : EL-VATP-11368
Quick Answer: The Temperature Measurement and Calibration Apparatus is a desk or bench unit with eight different temperature measurement devices, which students compare and calibrate against a built-in reference sensor. A display shows the reference temperature, barometric pressure and the local boiling point of water.

Key Features
- Eight temperature measurement devices with their characteristics shown side by side
- Insulated icebox for crushed ice and a fully guarded water heater tank with immersion heater
- Liquid crystal temperature indicator strip on the heater tank as an extra reference
- Display calculates the local boiling point of water from the built-in barometric pressure sensor
- Water level float switch and temperature cut-out switch turn the heater off at low water level
- Front-panel sockets with an amplifier, constant current and voltage sources, a resistive bridge and simulated resistances

About This Product
The apparatus shows why two thermometers in the same water can disagree. Students work between the ice point and boiling, see temperature lag with a thermowell, find how surface emissivity misleads an infrared thermometer, and learn how lead resistance, amplification and the choice of power source affect resistance devices and thermocouples.
Frequently Asked Questions
How does the apparatus account for local air pressure?
A built-in pressure sensor reads the barometric pressure, and the display calculates the local boiling point of water from it.
Can it show the limits of infrared thermometers?
Yes. A window beside the indicator strip lets students aim an infrared thermometer at a matt black or a brushed steel surface on the heater tank, showing how emissivity affects the reading.
