HUG Water Calorimeter V1.0

One of the two 1 watt heaters exposed.

View inside the water reservoir where the pumps can be seen with a filter.

View of the Calorimeter, the water reservoir, and the heat pump all together in the lab.

View of entire apparatus in the workshop before it was brought out to the lab.

View of the heat pump unit as it was on the development bench.

View of the data acquisition and control boards. They are mounted to the foam, but not enclosed, since they generate heat and would change their own temperature a lot if insulated.

Thermistor plugged into the tubing.

View of edge of thermal isolation plates - two aluminum plates with a gap between them. Near the center of the plates are two heat exchanger blocks that the water runs through.

Another view of the thermal isolation plate

Top thermal plate of the calorimeter - temperature controlled water from the reservoir is pumped through a heat exchanger block mounted between rwo aluminum plates to help isolate the calorimeter beneath it from ambient temperature swings. Ambient isolation is key to making precice calorimetry, especially when you are measureing temperature rise to the milli-Kelvin.

Water reservoir for flow calorimeter. The tubes on the right go tot he solid state heat pump. The tubes onteh left go to the calorimeter.

Solid state heat pump - made from a thermo-electric assembly we had lying around, this can pump at least 200 watts out of the water reservoir. That is enough to handle at least a half dozen calorimeters simultaneously.

Water flow lines feeding the bottom plate, the top plate, and two lines to the core calorimeter. Note the precision flow adjuster valve that sets the rough flow range to the calorimeter.

A view of the soldering on the copper shell.

Copper calorimeter shell - Closed end. Notice that the closed end is fit with a very expensive, precision machined plug.

This is the thermistor and heater fittings. The orange/orange/white pair of wires goes to the thermistor. The other fitting is one of the heaters.
