The Ametek PTC155B115BSMMU1R11EASCT Professional Temperature Calibrator with Reference Sensor Input, -25 to 155°C, STS-150 Reference Sensor, Complete Set of Metric Inserts, Full EURAMET Calibration, Carrying Case with Trolley features an active dual zone temperature control which provides excellent temperature homogeneity in the well. This model combines lab features such as a wide temperature range, high accuracy, stability, and speed into a single industrial calibrator. The PTC-155 full color VGA display is very easy to read. The main temperature indications, like SET, READ, TRUE and SUT (Sensor Under Test), are always displayed at all stages of the programming or calibration procedure. The navigation is very logical to use and the display indicates all important information needed for the current function.

Mains Power Variance Immunity (MVI) improves temperature stability. Unstable mains power supplies are a major contributor to calibration inaccuracies. Traditional temperature calibrators often become unstable in industrial environments where large electrical motors, heating elements, and other devices are periodically cycled on and off. The cycling of supply power can cause lower quality temperature regulators to perform inconsistently, leading to both inaccurate readings and unstable temperatures. The PTC series employ the MVI, thus avoiding such stability problems. The MVI circuitry continuously monitors the supply voltage and ensures a constant energy flow to the heating elements.

Features include switch test calibration and auto step function. Switch test calibration is a perfect time saver. Start the switch calibration and come back to note the results after the test. In autostep mode, as many as 20 temperature steps can be programmed including dwell times. Just start the sequence and the calibrator will complete the test.

The PTC is supplied with our highly recommended calibration software JofraCal. All calibrations can be documented with a certificate, given that the PTC is controlled from a PC. When the calibrator has reached the desired temperature and stability it will prompt you to type in the DUT temperature. JofraCal documents all calibration needs within temperature, pressure and process calibration

The included STS-150 reference sensor is angled at 90° and is only slightly higher than the top of the PTC calibrator. The unique design makes it possible to calibrate threaded sensors and sensors with connection heads without any problems.
