Process, Pressure & Temperature Calibrators

Calibrators check and adjust pressure, temperature and electrical instruments against traceable references, in the field and in the workshop. Seven Star LLC, an independent supplier in Muscat, supplies calibration equipment from Beamex, Fluke, Additel, Isotech, Druck, Palmer Wahl, Martel and others to maintenance teams and laboratories in Oman and the GCC.

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.
