Test chamber repair –
Testing chambers are a significant investment that require regular monitoring to ensure proper performance. It is very likely when purchasing a testing chamber that it came with a maintenance and protection agreement. In such cases, a technician will make scheduled visits to check all of the various functions of the device. There are specific systems on a chamber that need to be assessed for malfunctions and wear. This is especially true if the unit is required to produce exceptionally low temperatures.
The National Institute for Standards and Technology, NIST, a branch of the United States Department of Commerce, has a set of requirements for equipment designed to test, measure, or quantify data in laboratories and testing facilities. Testing chamber manufacturers train their technicians to abide by the regulations stipulated by the NIST, which guarantees that the service you receive will meet the highest standards.
A major factor in the repair of a testing chamber is its cooling system that uses a refrigeration process to produce extremely low temperatures. The system requires uninterrupted airflow over the cooling coils to perform properly and will need to be checked using gages designed for that purpose. Since it is a refrigeration system, maintenance requires monthly visits from a technician.
The issue of airflow is also a concern for adjusting and regulating the temperature in the chamber. Repairs begin with a calibration to see how well the unit performs at various temperatures. The technician in this case uses various computer programs that give a read out of the chamber’s performance and provides necessary adjustment data.
Though on-site maintenance is common, there are incidents when the chamber may have to be returned to the manufacture for a complete overhaul. This normally happens when the equipment has had constant use over an extended period of time. In shop repairs take the form of upgrading, refurbishing, and replacing or repairing of worn parts as well as a thorough examination of technical functions to bring them up to the latest standards.
Certain in house practices can serve as preventative maintenance such as reading the test chamber instructions and training the staff who regularly use the device. A daily examination of the performance of critical functions can alert users for the need to make adjustments or call for a technician.
To get the most from a testing chamber, it is important to have it evaluated for upgrading or repair. Manufacturers have processes in place to keep a testing chamber running at peak performance.
