Unique temperature performance Unique reference sensors The PTC series of calibrators provides precision temperature calibration of sensors, whatever the type or format. This is accomplished through an innovative active dualzone heating technology. The new STS-150 reference sensors are angled at 90˚ and are only slightly higher than the top of the PTC calibrator. The JOFRA PTC-series features our well-known active dual-zone heating technology. Each heating zone is independently controlled for precision temperature calibration. The homogeneity in the lower part is close to that of a...

d fast itive an ! Intu tion naviga Integrated support rod The integrated support rod is part of the reduced weight philosophy. It is lightweight and very easy to mount on the PTC. Two fixing holes are integrated in the calibrator where the support rods can be mounted. MVI - Secure temperature stability Easy-to-read color display and user-friendly navigation The 5.7” full color VGA display is very easy to read. The main temperatures, like SET, READ, TRUE and Sut (Sensor under test), are always displayed at all stages of the programming or calibration procedure. The navigation is menu-driven...

Maximum and minimum temperature The PTC model B is equipped with a built-in accurate measuring circuit for sensor-under-test (input), which enables measurement of virtually any type of temperature sensors including: resistance thermometers (RTD), thermocouples (TC), transmitters, milliamps (mA) and thermostats. From the setup menu, the user can select the maximum and minimum temperature limit for the calibrator. This function prevents damage to the sensor-under-test caused by excessive temperatures and it helps reduce sensor drift from exposure to high temperatures. This feature can be...

Calibration of up to 24 sensors with JOFRA ASM Using the JOFRA PTC series together with the ASM, Advanced Signal Multi-scanner, offers a great time-saving automatic solution to calibrate multiple temperature sensors at the same time. The ASM series is an eight channel scanner controlled by the JOFRACAL software on a PC. Up to 3 ASM units can be stacked to calibrate up to 24 sensors at a time. It can handle signals from 2-, 3- and 4 wire RTD’s, thermocouples, transmitters, temperature switches and voltage. al Option re mwa PTC fir e pakag Optional PTC firmware package Optional feature for B...

Thermocouple input PHYSICAL SPECIFICATIONS Weight and instrument size (without carrying case) (including solid protective carrying case) - (including solid protective trolley carrying case) - (carrying case only) - (carrying case only) - Mains specifications Weight of non-drilled insert (approx.) Use of other inserts may reduce performance of the calibrator. To get the best results out of the calibrator, the insert dimensions, tolerance and material is critical. We highly advise using JOFRA inserts, as they guarantee trouble free operation. PTC • Professional Temperature Calibrator
