4878 Automated Liquid Sampler

Parr’s new 4878 Automated Liquid Sampler allows the collection of multiple samples at a user defined interval without requiring the presence of an operator for sample collection. In addition, the contents of the dip tube and sample line can be cleared between each sample to ensure each sample is representative of the fluid inside the reactor at the time of sample collection.

Parr Instrument Company’s technical expertise was requested by Discovery Channel’s MythBusters television program to help provide data for one of their myths. The myth in question was if a rocket could be fueled with gummy bears or fecal matter. The MythBusters team contacted Parr for help determining the calorific values for each potential fuel.  A calorimeter is the instrument of choice when experimentally determining the energy release of solid and liquid fuels.

Parr’s Calorimeter Product Manager Steve Lierly visited the set of the show in California to run tests with Parr’s newest calorimeter, the 6050 Compensated Jacket Calorimeter. Mr. Lierly and the calorimeter appear in MythBusters “Rocketman” episode which originally aired on February 20, 2016.

Parr Instrument Company was one of nine companies chosen as a Pacesetter company to jump start the 2015 United Way campaign. Parr helped provide leadership and excitement for the rest of the community to increase their giving. Parr employees participated in a Day of Caring where employees had a chance to give back to the community where they live and work by volunteering in support of United Way programs.

Jim Nelson said, “I am blown away by the generosity of Parr employees and of the many others in the Quad City community who continually donate to United Way.” Read more.
