The Parr 1341 Plain Jacket Bomb Calorimeter is a reliable and straightforward instrument designed for precise measurement of heat of combustion in a static jacket environment. Known for its simple, robust construction, the calorimeter operates near room temperature without active jacket temperature control, making it ideal for labs requiring repeatable results with minimal complexity.
Product Features
- Static jacket design for operation at or near room temperature
- Compensation for heat loss/gain via heat leak correction measurements
- Simple, robust construction for reliable operation
- Requires external oxygen source, deionized water, and ignition unit
- Includes 6775 Digital Thermometer with 0.001°C resolution and 10–40°C range
- Oval bucket and oxygen fill connection included
- 6008 Bomb Maintenance Kit supplied for upkeep
- Compatible with PARR oxygen bombs (sold separately)
Static Jacket
Although commonly called a plain calorimeter, this instrument is technically a static jacket design. It functions at or near room temperature with no provision for controlling the jacket temperature. Compensation for heat loss or gain during tests is achieved through correction based on heat leak measurements before or after each test. With careful application of temperature rise and heat leak corrections, excellent repeatability can be achieved.
Laboratory Requirements
The calorimeter requires a source of 99.5% oxygen, deionised water, and an ignition unit for operation.
1341 Plain Calorimeter
The 1341 Plain Calorimeter includes the following components:
- 1341 Calorimeter
- Oxygen Bomb
- Oval Bucket
- Oxygen Fill Connection
- 6775 Digital Thermometer
- 6008 Bomb Maintenance Kit
6775 Digital Thermometer
The 6775 Digital Thermometer provides digital precision and reliability for temperature measurements. The thermometer has a working range of 10°C to 40°C and a resolution of 0.001°C. The readout is displayed on a clear LCD screen. In addition to displaying temperature, the thermometer includes a timer that can be used to manually record the time intervals of specific temperature readings. The thermometer uses high capacity lithium batteries which provide approximately 200 hours of operation.
Designed for use with the PARR 1341 Plain Jacket Calorimeter, the 6775 is a replacement for the 1604 and 1623 liquid-in-glass thermometers.
Benefits
- Reliable and repeatable combustion measurements with minimal setup complexity
- Robust and low maintenance design suited for routine laboratory use
- Digital thermometer enhances accuracy and ease of temperature monitoring
- Compact and user-friendly design reduces operator error and maintenance downtime
