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
