JOFRA RTC-159ATemperature Calibrator

Perfect temperature
homogeneity in the insert
Even when calibrating large sensors or many sensors at once, the unique dynamic load compensation (DLC) system in combinationwith JOFRA′s active dual-zone technology ensures perfect temperature homogeneity.(B and C models only)
Fastest calibration
possible The efficient free piston stirling cooler (FPSC) technology is used to secure fast cooling and heating temperature
High accuracy Down to ±0.06°C (±0.11°F) using the external reference sensor. 4-wire True-Ohm-Measurement technology is used

The RTC series of calibrators provides precision temperature calibration of sensors, whatever the type or format.
The JOFRA RTC-series features our well-known active dualzone heating technology. Each heating zone is independently controlled for precision temperature calibration. The homogeneity in the lower part is close to that of a laboratory liquid bath. The lower zone ensures optimum heat dissipation Throughout the entire calibration zone. The upper zonecompensates for heat loss from the sensor-under-test and from the open top. This design also eliminates the need for extra insulation of sensors-under-test and makes it possible to calibrate any type of mechanical sensors.
The RTC-159 can perform calibration over a very wide temperature range starting from -100°C and up to 155°C(-148 to 311°F). This makes it possible to perform calibration of sensors in applications ranging from ultra-coolers to autoclaves.
Reading of Sensor-Under-Test (Model B only)
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), voltage (V) and thermostats.
RTC calibrators can be user-programmed from the keyboard for fully-automatic sensor calibrations. Once the unit is programmed, the instrument is self-operating and performs the configured calibration routine. All calibration data and results are stored and can be read on the display.
Switch test (Model B only)
Users may perform a thermoswitch test and find “Open”,“Closed” and the hysteresis (deadband) automatically. Theinstrument retains the last twenty test results.
