AOIP-Drago 934, stirred liquid bath, dry block, Blackbody source & Fixed Point system (Model:DRAGO 934)

 Drago 934 is a calibration liquid bath for temperature thermometers from 30°C (in ambient of 20°C) to 250°C. It has a large calibration volume, 65 mm x 160 mm deep, which makes it ideal to use as a portable liquid bath. The stirred liquid bath is suitable for temperature sensors of all types, sizes and shapes. 

The liquid bath can provide smaller calibration uncertainties than a dry block and, when used with suitable reference thermometers, accuracies of up to 0.005°C can be achieved. The sensors can be placed directly into the stirred liquid thus avoiding the need for specially drilled blocks. Temperature homogeneity is ensured by constant liquid stirring. It is not necessary to empty the block to move the system from one place to another, a cap ensures the sealing.

In the optional dry block mode, the large 65 mm diameter block allows for the calibration of either larger probes or for calibrating many sensors simultaneously over the range 30°C to +250°C. Fully compatible with the leading I-Cal Easy automatic calibration software you can also benefit from the combination of flexibility and large calibration capacity.

Combined with accessories, it can also be converted into a Blackbody Source for infrared thermometers, a surface sensor calibrator and ITS-90 Fixed Point cell with calibration uncertainties up to 0.0005ºC.

Drago 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 uncertainties.

Key features:

• Large calibration volume: 65 x 160 mm diameter
• Portable liquid bath, convertible for dry block operation
• Calibration as a liquid bath or a dry block: thermocouples, platinum resistance thermometers, thermistors, liquid in glass, thermostats, semiconductor types
