Check the listing for details. TecQuipment TD400 Temperature Measurement and Calibration Testing Station. Condition: Used. Listed at 7499.95 USD. IN HAND NO LEAD TIMES! UNIT WILL BE CRATED FOR SHIPMENT AND WILL NEED TO BE SIGNED FOR UPON DELIVERY! FREE DOOR TO DOOR DELIVERY IN THE CONTIGUOUS UNITED STATES Studies the accuracy, linearity and important characteristics of popular temperature measuring devices. The Temperature Measurement and Calibration apparatus (TD400) fits on a desk or bench top. It includes four different temperature measurement devices including a bi-Metal thermometer vapor thermometer, built-in reference display and liquid crystal estimate monitor. The built-in precision reference sensor works as an accurate temperature reference. A display shows the temperature from the reference sensor and the local (barometric) pressure from the built-in pressure sensor. The display also calculates the local boiling point of water based on the barometric pressure. Students add crushed ice (not supplied) to the insulated icebox and clean water to the fully guarded water heater tank. A carefully rated immersion heater in the tank heats the water steadily up to boiling, giving time to take accurate results. The water heater tank includes a water level float switch and a safety temperature cut-out switch to turn off the heater in case of low water level. The water heater tank has a drain tap for connection to a suitable container or local water drain. This helps students to change the heated water safely and quickly, reducing experiment time. As an extra reference, a liquid crystal temperature indicator strip on the front of the heater tank shows its temperature during experiments. The equipment is compatible with a thermowell that would work with the gas (vapour) thermometer( included ) to show temperature lag. Sockets on the front panel can connect to electronic circuits and a multi-line display that work with the electrical resistance and thermocouple devices, additional wiring kit would be needed for the socket lab function . The sockets include resistances to simulate a resistance device and show the problems of adding resistances (for example – long wires) to your measuring circuits. The electronic circuits also include: An amplifier to increase the output of the thermocouples for more useful voltage measurement. Constant current and voltage sources, and a resistive bridge. These show the problems with different measurement circuits and power sources for electrical temperature measurement devices. This equipment can connect to TecQuipment’s Versatile Data Acquisition System (VDAS®). Key features: Built-in water heater tank with protective guard and drain tap for safe experiments Works with TecQuipment’s Versatile Data Acquisition System (VDAS®) for simple and reliable recording and processing of results Built-in pressure sensor (barometer) with display of local water boiling temperature. Built in auto shutoff due to lack of tested medium. Learning outcomes: Demonstration of heat transfer from one fluid to another through a solid wall. Introduction to the logarithmic mean temperature difference in heat exchangers. Comparison of different types of heat exchanger in terms of performance, size and relative cost (only if you have two or more optional heat exchangers). Flow-through and batch heating, with or without stirring, using a heating jacket or a coil. x1 is included in this listing please see all photos before bidding additional photos can be sent if necessary you will receive the item(s) pictured please ask any and all questions before buying.
