The most remarkable characteristic of 

BL series represents also its most valuable 

benefit: 

Simplicity ! 

In fact BL series has been designed to make 

easy all possible Temperature Calibration Procedures 

to any operator, in all types of Industries. 

Specific for Field Calibration of a variety of 

Temperature Devices, such as T/C, RTD, 

Thermometers, Temperature Recorders, Indicators 

and Switches, BL series may successfully 

be used in Laboratories and Workshops 

either for Instruments Calibration or 

Testing/ Commissioning purposes. 

As most demanding International Standards 

require, BL series allows to carry out the 

Calibration Procedures by using the Comparison 

Method. 

This method implies that both the Temperature 

Device under test and the Reference 

Temperature Sensor are exposed to the same 

temperature. 

To calculate the error of the Device under 

test, each measurement, relevant to each 

calibration point, must be compared with the 

corresponding measurement taken from a 

Reference Sensor. 

BL Series Dry Blocks does not use the Reference 

Sensor as sensing element of the Temperature 

PID Controller. It uses, instead, a 

standard commercial type of RTD or, depending 

the models, a thermocouple. 

This ensures a much longer life to the highly 

expensive Reference Sensor and improves the 

reliability and availability of both the Reference 

Sensor and the Dry Block. 

That is why it is meaningless to provide any 

accuracy figure to BL series. More correctly 

the accuracy to be considered is that of the 

chain that include the Reference Sensor and 

Temperature Calibrator. 

Periodic certifications are consequently 

stranger to BL series (which is limited to 

Reference Sensors only). Obviously any possible 

maintenance or service to BL series 

does not require any re-certification procedure.

• FLEXIBLE OPERATIONS 

Due to the possibility of single to multiple 

arrangements, BL series Dry Blocks allows 

the ideal operating flexibility together with a 

large spectrum of possible operation modes. 

In fact the user may practice any manual 

conventional calibration mode or Computer 

Supported Calibration Procedures. Moreover 

the computer Operations can be driven by the 

combination of the Scandura Calibration and 

Maintenance software with other Scandura 

dedicated hardware (i.e. SCS-T, the 

Automatic Temperature Calibration Station): 

fully automatic calibration procedures are 

made possible to BL series. 

For BL series the concept of flexibility is 

extended also to any applicable Standard as 

well as to any Reference Sensor from any 

maker. 

The selection of such sensors shall preferably 

be made among the many types Scandura 

offers for a wide range of different 

applications. 

Also the complementary Measuring and 

Indicating Instruments can be chosen with no 

limitations according to the desired Functions, 

the expected Accuracy and Resolution, the 

Hard-copying or Computer management 

requirements etc. 

• RECOMMENDED ACCESSORIES
