The Model 5609 secondary reference temperature sensor is new to the company's line of high-temperature platinum resistance thermometers (PRTs). The 100-ohm sensor has a temperature range of -200°C to +670°C, with short-term repeatability and long-term drift of ±0.01°C at 0°C. The unit is available in either 1/4 in. or 6 mm diameters to match the demands of an international market. One-quarter-inch-diameter PRTs come in sheath lengths of 12, 15, or 20 in. Six-millimeter diameter PRTs come in sheath lengths of 300, 400, or 500 mm. In addition, the device may be ordered with a certificate of compliance or optional NVLAP accredited calibration from the manufacturer. Options include sensor characterization or full system calibrations that include the performance of the sensor and readout together. This reduces the cost of ordering system calibrations. Both types of calibrations are performed in the company's laboratory, NVLAP lab code 200348-0. The option to purchase without a calibration adds value for international customers preferring traceability to their local NMI, as well as to those with less demanding calibration requirements. Applications include laboratory calibration and calibration in manufacturing facilities in biotech, pharmaceutical, and process industries.
