The Isotech Venus 4951 temperature calibrator can be used as a dry block or liquid bath. Accessories are available for converting to a stirred liquid bath, surface
sensor calibration, to calibrate infrared thermometers and even to use as an ITS-90 Fixed Point System with calibration uncertainties as small as 0.0005°C. With excellent
stability and distributed heating / cooling zones for good uniformity these calibrators offer proven thermal performance, are easy to use, and available in three models.

Basic Model

• Digital display of set and nominal block temperature
• Use with a separate external indicator to compensate for gradients and loading
• Calibrator does not need calibrating; only the indicator & sensor need re-calibration
• Cal Notepad software
• Serial PC interface

Site Model

• Digital display of set and nominal block temperature
• Single channel indicator for reference probe
• Best Practice calibration with established traceability and uncertainty
• Re-calibration requires sending whole unit in
• Cal Notepad software
• Serial PC interface

Advanced Model

• Digital display of set and nominal block temperature
• Three channel indicator for reference probe and units under test
• Advanced features including automatic temperature cycling and logging
• Best Practice calibration with established traceability and uncertainty
• Re-calibration requires sending whole unit in
• I-Cal Easy LOG software & built-in web server
• Ethernet & USB host PC interface
