The CalistoPLUS2250 range offers outstanding performance in an easy to use portable package. As part of the ISOCAL-6 series the CalistoPLUS2250 can be used as a Dry Block, a Liquid Bath, a Blackbody Source for infrared thermometers, a Surface Sensor Calibrator and for performance to a few mK (0.001ºC) ITS-90 Fixed Points. The CalistoPLUS2250 is available in two models, the BASIC (B) and the SITE (S). The B model includes a sophisticated temperature controller with a dual display for Set Temperature and Dry Block Temperature, refer to page 27 for further details. The S model additionally includes an in-built indicator to which an external temperature sensor can be connected.
For Dry Block use the unit under test may be compared to the controller value, the use of an external probe connected to the indicator of the Site model which compensates for the temperature gradient and loading errors, is recommended. This gives greater accuracy and traceability meeting the requirements of ISO 9000 and other quality standards.
For Liquid Bath, Surface Sensor or Blackbody use an external thermometer should always be used - either with the S model or the B model and a separate stand-alone indicator. For laboratory use the CalistoPLUS2250 can be used with a laboratory performance temperature indicator.
Includes as standard: Windows Software, Computer Interface and a Ramp to Set Point Feature.
Increased resolution of ±0.01 available throughout the range via the PC interface and from -19.99 to +99.99 locally on the auto-ranging front display. The controller features multi-point block to display correction giving good absolute accuracy.
The S model has universal sensor input allowing Platinum Resistance Thermometers, Thermocouples (Types K, N, R, S, L, B, PL2, T, J and E) along with Linear Process Inputs including 4-20mA current transmitters to be displayed on the inbuilt indicator. The indicator can be programmed with up to five calibration points to provide high accuracy digital probe matching.
The indicator and controller are both addressable over the communications link.
New! The Site model can now be used with the supplied Cal Notepad software to test thermostats.
