Model 1152 Digital Conductivity Meter
Model 1152 Digital Conductivity Meter
The only conductivity meter in the world approved as intrinsically safe by ATEX, UL, CSA, ULC, and LCIE - and the only ASTM D1655 & D7566 approved conductivity meter with full intrinsic safety certification for hazardous environments.
The Emcee Model 1152 Digital Conductivity Meter measures the electrical conductivity of fluids - primarily hydrocarbon fuels such as jet fuel - in picosiemens per meter (pS/m) as defined in ASTM D2624. It is used in laboratories and in the field to verify that fuel conductivity is high enough to safely dissipate static charge, preventing explosion and fire hazards during high-rate pumping and filtration. The Model 1152 is sealed against liquid intrusion, built tougher, and backed by the only full intrinsic safety certification in its class including ATEX, UL, CSA, ULC, and LCIE (Europe/UK).
Manufactured in a USA ISO/IEC 80079 facility, calibrated in an ISO/IEC 17025 laboratory, and compliant with ASTM D2624, IP 274, and ISO 6297.

What is the Model 1152 used for?
The Model 1152 Digital Conductivity meter provides a measurement of electrical conductivity of fluids in conductivity units (CU), which are defined as picosiemens per meter in ASTM D2624. The rugged Electro/mechanical design of the Model 1152 meter facilitates ease of use for both laboratory and field applications. Initially the meter was designed and developed for safety reasons to measure the electrical conductivity of hydrocarbon fuels, particularly jet fuels. Subsequently, the meter was modified with other conductivity ranges to accommodate measurement of a variety of fluids for use in many different applications.
Why does fuel conductivity matter for safety?
Hydrocarbon fuels typically have low electrical conductivity and consequently are susceptible to retaining a static charge. Static charges are induced, especially, when the fuel is pumped at high rates through filters. Due to the relatively low conductivity, the static charge does not readily dissipate and is retained for a considerable period of time. This condition can result in an explosion and/or fire. Since conductivity can vary with temperature it is important to record the fuel temperature at which the measurement was performed.
How is conductivity used in process control?
In addition to safety reasons, electrical conductivity of fluids can be monitored for process control. Proper addition and mixing of various ingredients can be monitored at different stages of production. These applications are not limited to hydrocarbons, but have been expanded to other products; such as paints, solvents, inks, and other non-organic items. The stainless steel probe is relatively unaffected by most acidic and caustic solutions.
How does the Model 1152 work?
The EMCEE Model 1152 meter consists of an electronics assembly and a detachable stainless steel probe. The probe, which is similar to a capacitor having concentric electrodes, is immersed into the fluid up to the set of holes closest to the electronics assembly. Depressing the “M” pushbutton causes a relatively small direct current to flow through the fluid between the electrodes. The current is amplified in the electronics assembly and is displayed on the liquid crystal display in picosiemens per meter (pS/m).
