Laboratory Grade Calibration Standards

Temperature Standards consist of ultra-stable NTC thermistor probes assembled into thin wall stainless steel housings with shielded extension leads to laboratory calibration standards. The non contact infrared thermometer thermistors used receive special processing to ensure long-term stability. All of our temperature standards are ruggedly constructed and are suitable for liquid immersion. A precision calibration, traceable to the National Institute of Standards and Technology, is provided with all temperature standards. Uses of the solid state temperature sensor include secondary or working temperature standards for all laboratory metrology applications, general laboratory and hospital use, clinical applications and process temperature measurements.
