STANDARS

ASTM D2624 – Electrical Conductivity of Aviation and Distillate Fuels
LCIE Certification
ATEX II 2 G Ex ia IIA T4
Intrinsically Safe approval
ASTM Inter-Laboratory Test Program

Monitoring aviation fuel conductivity is a critical safety requirement in aircraft refueling and fuel handling operations.

Hydrocarbon fuels such as JET A-1 naturally exhibit low electrical conductivity. During high-flow pumping, filtration, or hydrant transfer operations, electrostatic charges can accumulate. If conductivity levels are insufficient, charges may not dissipate properly, increasing the risk of spark ignition or explosion in hazardous classified areas.

The EMCEE 1153 conductivity meter measures fuel conductivity in pS/m according to ASTM D2624. It is widely used by:

Aircraft refueling operators
Airport fuel depots
Hydrant system maintenance teams
Fuel quality control laboratories
Additive injection monitoring operations

The stainless-steel probe is immersed into the fuel sample while ensuring proper grounding. Measurement is completed within 3 seconds and automatically stored.

Its ATEX II 2G Ex ia IIA T4 certification allows safe operation in explosive gas atmospheres typically found in aviation fuel environments.

Beyond aviation, the instrument is also suitable for:
