Ametek RTC-156 (-30˚C to 155˚C) & RTC-157 ( -45˚C to 155˚C) Reference Temperature Calibrators 

INTRODUCING NEW!! JofraCloud Option for any RTC or PTC Calibrator

 

Dual-zone heating technology and dynamic load compensation for superior temperature homogeneity


The Ametek RTC-156 and RTC-157 reference temperature calibrators combine Ametek's unparalleled experience with temperature calibration with cutting edge technological features creating the most sophisticated dry block temperature calibrators on the market.

The Ametek RTC-156 and RTC-157 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-156 and RTC-157 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-156 and RTC-157 feature a rugged, lightweight design and multi-hole inserts that cover most commonly used sensor sizes.


NEW!! JofraCloud Option for any RTC or PTC Calibrator

JofraCloud

JofraCloud is a new way to perform remote reading and setting of our temperature calibrators over an unlimited distance. JofraCloud is a gateway that has transmission coverage equal to a smartphone.

The data is presented as a copy of the calibrators display, and can be viewed at jofracloud.com. The webpage is accessible via a browser on any device - PC, laptop, tablet, or smartphone.

The gateway can be attached to any RTC or PTC calibrator and reads data from the calibrator every 2 seconds.

Remote Setpoints – Select a new temperature setpoint on your calibrator using your device.
Documented Stability Reporting – When the calibrator reaches the set temperature and gains stability, an emailed report will be sent to your controlling device.  
On Demand Reporting – Generate a timestamped emailed report at any time. 
* When using JofraCloud from your PC, you can get an audible notification when the calibrator reaches stability.
* Control and communicate up to 5 calibrators simultaneously with a single Gateway.
* Print a timestamped PDF as documentation.
