Venus calibrates temperature probes from -35°C (in ambient of 20°C) to 140°C with unrivalled flexibility.
As a traditional industrial dry block calibrator, several thermometers can be quickly calibrated. Accessories are available to convert it to a stirred liquid bath, for 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.Venus 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.The S model additionally includes an in-built temperature digital indicator to which an external temperature sensor can be connected. It ensures traceability, best practise and adherence to quality standards and calibration to the smallest of uncertaintiesFor 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 and blackbody use, an external standard probe should always be used, either with the S models indicator or a separate stand-alone indicator.For laboratory use, Venus can be used with a laboratory performance temperature indicator.
