Ametek RTC-158 Reference Temperature Calibrators -22 to 155°C (-13 to 311°F), Basic Model. The Ametek RTC-158 and RTC-250 are advanced reference temperature calibrators. Combining dry-block and liquid bath technology, the RTC-158 and RTC-250 are designed to calibrate oddly sized and shaped sensors or multiple sensors at once. Both calibrators offer a host of innovative features along with AMETEK's long history of providing reliable, low-drift calibration instruments. The Ameteck RTC-158 has a temperature range of -22° to 155°C (-8° to 311°F), while the RTC-250 has a temperature range of 28° to 250°C (82° to 482°F). Both units boast outstanding accuracy and stability while featuring Ametek's Dynamic Load Compensation (DLC) system that provides perfect temperature uniformity in the insert no matter the number or size of the sensors immersed. The calibrators also offer unique intelligent sensors for plug ‘n' play connectivity, an easy-to-read full-color 5.7-inch VGA display, and a USB connection for improved communications and software downloads. The Ametek RTC-158 and RTC-250 reference temperature calibrators are available in three configurations: RTC-A reference temperature calibrator, RTC-B reference temperature calibrator with input for reference sensor, DLC sensor and sensors-under-test, and RTC-C reference temperature calibrator with input for reference sensor and DLC sensor. The RTC-158 and RTC-250 can be used without an external reference sensor. However, users will obtain better accuracies and realize the calibrator's full potential by utilizing the STS-200 reference sensor. Both the STS-200 and DLC sensors contain all individual calibration data regarding the sensor, allowing users to change the reference sensor and be up and running immediately. The RTC-158 and RTC-250 feature a rugged, lightweight design and multi-hole inserts that cover most commonly used sensor sizes. A unique design allows the units to calibrate threaded sensors and sensors with connection heads. The 160 mm deep well has a diameter of 63.5 mm, which is twice the size of any other dry-block calibrator. Either calibrator can be used both as a dry-block or liquid calibration bath with magnetic stirrer.
