Overview:
Quartz dry block temperature calibrator is a portable instrument to be used in field or within your laboratory, suitable for the test and the calibration of temperature sensors like thermocouples and PT100 resistance thermometers.   As the Quartz dry block temperature calibrator offers the possibility to set the rising and falling generated temperature trends, the combined use of the front panel electrical connections, will make very easy to check and adjust also the intervention point of temperature switches.    The Quartz dry block temperature calibrator is heated and cooled by a static generation system based on Peltier cells, making possible the total absence of thermal convections, typically performed by external fluids. Dry block thermostatic element is made by a solid aluminium metal block, with the well hole internal diameter of 35 mm, with a depth of 135 mm. Within the equalization block can be fitted the reduction insert adapters, suitable to allow the insertion of several temperature probes with different shapes and sheat diameters (as standard Quartz dry block temperature calibrator will be supplied with six holes insert adapter with ID as 4; 4.5; 5.5; 6.5; 8.5; & 10.5 mm: others insert adapters can be supplied with custom hole sizing, or as solid insert to be drilled). Temperature generation of Quartz dry block temperature calibrator (from -25 °C, with 22°C as ambient temperature, up to +150°C), is managed by a microprocessor controller capable to achieve a ±0.03 °C stability of the generated value (resolution up to 0.01 °C). The Quartz dry block calibrator offers a visualization display for the measurement of generated temperature value with a better than ±0.15 °C accuracy. By the same display and the front four pushbutton keys is possible to operate a very easy and friendly structured menu capable to allow the operator to entry to all Quartz dry block calibrator functions. As option, Quartz dry block calibrator can be equipped with a two configurable channels input board (each channel can be set for three or four wires RTD PT100, or for thermocouples J, K, N, R, S), suitable to be used for comparative measurement actions between the unit under test, and the standard reference probe, both connected each to mentioned input board, and fitted in the same dry block temperature generation well. The Quartz dry block calibrator local display will shown the three temperatures, the one generated by the dry block temperature calibrator, the one from the unit under test, and the one from the standard reference probe. This will translate your Quartz dry block calibrator into a true ISO9000 compliant calibration bench, that can also be handled and automated for repeated calibration procedure by specific software like the AQ2sp (contact Spare for any further detail), that will act by the RS232 serial port supplied as standard on the Quartz dry block calibrator. Spare can offer you a complete range of dry block temperature calibrators, suitable to generate and measure several temperature ranges (up to +1100°C as maximum): please contact us for any further detail.

Quartz dry block temperature calibrator accessories:
If the dry block temperature calibrator shall be used for the test and calibration of particular shaped or with specific sheat diameters temperature sensors, it would be possible to supply optional insert adapters, specifically tailored to meet your needs, improving the final performance of the dry block temperature calibrator:
- optional solid insert adapter (to be drilled), or with custom holes,
- optional metal transportation suitcase,
- optional AQ2sp full software (see below).

 

AQ2sp software for dry block temperature calibrators:
As standard Quartz dry block calibrator is supplied with a 60 days shareware version of AQ2sp software suitable to allow the user to understand and appreciate the features offered by such software tool. By the AQ2sp software any compatible dry block temperature calibrator can be transformed into a true automated calibration bench, with a friendly approach that will not require for any particular operator skills. AQ2sp is a very intuitive software working with Windows™ environment. Once the software have been installed on any PC, it will allow the user to the following main functions:
- total dry block temperature calibrator control from the PC
- manual or automatic calibratio of one or more temperature sensors
- temperature sensors life cycles or stress tests
- storage, handling and printout of results in total compliance to ISO9000.

Quartz dry block temperature calibrator typical applications:  
The Quartz dry block temperature calibrator make possible the test and the calibration of any temperature sensor (e.g. thermocouples or PT100 RTD), as also of any temperature switch (allowing to see the alarm trip intervention point by a local visual confirmation as a panel light). When combined with the AQ2sp software, the dry block temperature calibrator will allow for repeated calibration or testing procedure, as usually required by a temperature sensor manufacturer or OEM users.
