About Process, Pressure & Temperature Calibrators
Calibrators check and adjust pressure, temperature and electrical instruments against traceable references, in the field and in the workshop.

Types of calibrator in this category
Documenting multifunction calibrators such as the Beamex MC6 and MC6-Ex, Druck DPI 620 Genii, Additel ADT226 and Palmer Wahl C150 calibrate transmitters, switches and loops. Pressure calibrators and controllers like the Additel ADT760, ADT761 and ADT762, Druck PACE5000 and PACE6000 and Beamex PGM hand pumps cover pressure, while temperature calibrators such as the Fluke 724, Isotech Isocal-6 and Additel ADT878 dry wells check sensors and thermostats. Laboratory references including the Fluke 5500A calibrator, 8508A reference multimeter and Isotech TTI-22 thermometer complete the range.
How to select a calibrator
List the instruments you need to calibrate and their ranges and accuracies; the calibrator should be several times more accurate. Choose documenting calibrators if you use calibration management software, and intrinsically safe versions for hazardous areas. For pressure decide on pump type and range modules, and for temperature the dry block range and insert sizes.

Frequently Asked Questions
What is a documenting calibrator?
A calibrator that stores procedures and results and transfers them to calibration management software, removing manual records.
How accurate should a calibrator be?
A common rule is that the reference should be at least four times more accurate than the instrument being calibrated.
Can calibrators be used in hazardous areas?
Yes. Intrinsically safe models such as the Beamex MC6-Ex are certified for use in explosive atmospheres.
What is a dry block calibrator?
A portable heat source with a metal block and inserts that holds a stable temperature to check temperature sensors.
What should I send for a quotation?
The model, or parameters, ranges, accuracy, Ex requirement, accessories and quantity.
