Model 1152 Conductivity Meter for Fuel Testing

Emcee's Model 1152 Digital Conductivity Meter is the sole conductivity meter globally recognized as inherently safe by ATEX, UL, CSA, ULC, and LCIE. Furthermore, it is the only conductivity meter sanctioned by ASTM D1655 & D7566, with full intrinsic safety accreditation for hazardous settings.

This digital conductivity meter measures the electrical conductance of liquids, primarily hydrocarbon fuels such as jet fuel, in picosiemens per meter (pS/m), consistent with ASTM D2624 specifications.

Its application spans both laboratory and field settings to confirm adequate fuel conductivity for safe dissipation of static charge, thereby averting explosion and fire risks during rapid pumping and filtration operations.

The Model 1152 features protection from liquid ingress, boasts enhanced durability, and is supported by the sole comprehensive intrinsic safety accreditation within its category, encompassing ATEX, UL, CSA, ULC, and LCIE (Europe/UK).

The system is produced in a USA ISO/IEC 80079-compliant facility, precision-calibrated in an ISO/IEC 17025 laboratory, and adheres to ASTM D2624, IP 274, and ISO 6297 standards.

What Is the Model 1152 Used for?

The Model 1152 Digital Conductivity meter measures fluid electrical conductivity using conductivity units (CU), specified as picosiemens per meter under ASTM D2624. Featuring a sturdy electromechanical build, the Model 1152 device ensures straightforward operation across both laboratory settings and field environments.

Originally, this instrument was engineered to evaluate the electrical conductivity of hydrocarbon fuels, specifically jet fuels, for safety compliance. Over time, the unit was adapted to include alternate measurement ranges, enabling conductivity testing for multiple liquid types across diverse applications.

Why Does Fuel Conductivity Matter for Safety?

Since hydrocarbon fuels generally possess low electrical conductivity, they easily hold onto static charge. These electrostatic charges accumulate heavily when fuel moves rapidly through filtration systems. Owing to this minimal conductivity, the charge fails to discharge quickly, persisting for a significant duration instead. Such circumstances create a serious risk of fire or explosion.

Furthermore, because conductivity fluctuates alongside temperature changes, recording the exact fuel temperature during testing remains essential.

How Is Conductivity Used in Process Control?

Beyond safety considerations, fluid electrical conductivity serves to track manufacturing processes. Correctly incorporating and blending diverse components may be tracked throughout various production phases.

Far from being restricted to hydrocarbons, these uses now encompass additional materials such as paints, solvents, and inks, as well as other non-organic substances. Additionally, the stainless steel probe resists degradation from the majority of acidic or caustic liquids.

How Does the Model 1152 Work?

Featuring a removable stainless steel probe paired with an electronics unit, the EMCEE Model 1152 instrument assesses fluids directly. Functioning like a concentric-electrode capacitor, this probe is submerged in the liquid until it reaches the upper set of apertures.

Depressing the "M" button transmits a minor direct electrical current through the liquid separator. After amplification inside the main electronic package, this current shows on the digital screen, measured in picosiemens per meter (pS/m).
