7200 Precision Isoperibol Calorimeter

Overview

The 7200 Precision Isoperibol Calorimeter is Parr’s most precise model and features a sleek modern design with a large, adjustable display, updated CPU, and intuitive menu structure. The width of the 7200 has been reduced by two inches (5 cm) from the 6200 design, decreasing its benchtop footprint.

The traditional 1108P removable combustion vessel, bucket, and water jacket designs have been retained. These time-tested features afford the user complete control over the combustion process, making the 7200 the ultimate choice for precise research and development and quality control work.

Description

Isoperibol Jacket System

Outstanding thermal jacketing is provided by a circulating water system driven by a built-in, high capacity pump which maintains a continuous forced flow around the sides and bottom of the bucket chamber and through the cover as well. A sealed immersion heater and a built-in heat exchanger, both operated by the calorimeter controller, provide precise jacket temperature control.

10-inch Adjustable Touchscreen Display

The 7200 Calorimeter is controlled by a high-resolution touchscreen with excellent touch accuracy and display clarity. The tiltable screen accommodates users and lab benches of any height. The durable, scratch-resistant, and shatterproof screen can be operated while wearing gloves or with protective film.

Upgraded CPU and Software Interface

A new CPU board and redesigned menu structure takes maximum advantage of the larger tablet-like display, allowing rapid and intuitive navigation.

Automatic Oxygen Fill

To speed and simplify operation, the 7200 Calorimeter includes an automated touchscreen-initiated system to execute a filling sequence, once the filling connector has been slipped onto the inlet valve. This sequence charges the vessel with oxygen under the control of the main calorimeter controller.

Reliable Standard Oxygen Vessel and Compatibility with Many Other Vessels

The Parr 1108P Oxygen Vessel furnished with the 7200 Calorimeter will safely burn samples liberating up to 8000 calories per charge, using oxygen charging pressures up to 40 atm. An alternate 1108PCL bomb with superior resistance to chlorine and halogen acids is recommended for tests involving waste material and chlorinated samples. A variety of vessels are available for testing samples releasing from 52 calories (1109A semi-micro vessel) to 12,000 calories (1104 high strength vessel) per test.

Many User Options

Although specific procedures are recommended, various options are available to the user:

Program parameters can be adjusted to accommodate unusual sample sizes and precision requirements.
The calorimeter can be programmed to accommodate any titrant concentrations selected by the user.
Calorific values can be reported in any of several measurement units.
The calorimeter program can be adjusted to compensate for the subtle differences in the way acid correction values are handled in ASTM, BS, DIN and ISO methods.
Program controls can be protected from inadvertent changes.
A vessel usage tally can be maintained to notify the user when each vessel should be serviced.

Laboratory Requirements

The calorimeter requires a source of 99.5 percent oxygen and two liters of water per test. If a closed loop system is chosen, the water handling system must be installed so that the fan will not blow on the calorimeter.
