Standard Reference Materials: Description and Use of a Precision Thermometer for the Clinical Laboratory, SRM 934

摘要

Because of the high sensitivity to temperature of many facets of the clinical laboratory, e.g., in enzyme reactions and in pH and blood gas analysis, there is a need for accurate temperature measurement and its control. In order to help satisfy these needs and to aid in getting a usable and accurate temperature scale into the clinical laboratory, the National Institute of Standards and Technology developed SRM 934. This is a precision thermometer that is calibrated at 0 C, 25 C, 30 C, and 37 C. The description, calibration, and the procedures for proper usage of this thermometer are discussed. This SP 260 supersedes SP 260-48 describing both SRMs 933 and 934. SRM 933 will no longer be issued by the SRM Program. The publication is the same as SP 260-48 with the exception that all references to SRM 933 have been removed.
