DADT DIGITAL ACCESSORIES
Improve the performance of your deadweight tester |
 |
This pre-programmed, intrinsically safe accessory corrects for ambient conditions and inherent errors associated with any hydraulic or pneumatic deadweight tester application. It uses actual values rather than nominal values to correct for the specific gravity of location, masses of the weights, weight set buoyancy in the air, relative humidity, and temperature effects. Eliminates most errors by calculating the NIST formula provided by Test III data. Features fifteen engineering units with automatic conversion. Lets you use a psi tester for H2O calibrations. |

| TEMPERATURE CALIBRATION SOFTWARE |
AMECAL-TEMPERATURE & AMECAL-LIGHT
An easy way to run and document your temperature calibrations |
Simplify and improve the efficiency of your temperature calibrations using AMECAL-TEMPERATURE or AMECAL-LIGHT software. This WINDOWS®-based software makes use of standard WINDOWS tools including menu bars and icons and can be used with all JOFRA dry-block calibrators.
AMECAL-TEMPERATURE software provides you with an easy method for calibrating, write out calibration certificates, data logging, and managing your calibration data.
AMECAL-LIGHT software have all the same features but can not store your results.
The key to an easy setup of a calibration task is the unique "Icon bar". The "Icon bar" tells you where you currently are in the calibration process, starting with selection of the sensor to be calibrated and ending by performing the calibration. The AMECAL software will improve the accuracy of your calibrations. Select the right calibration "scenario" and the software will communicate with both the heating source and the JOFRA DTI-1000 reference thermometer at the same time. All "true temperature readings" will be taken from the more accurate JOFRA DTI-1000 thermometer! |
