1152 Digital Conductivity Meter Range (0 - 2,000 pS/m)

Product Code: 152 00 0000
ID: Emcee 1152
Specification:

Applications

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.

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.

Process Controls

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.

Theory of Operation

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 closet 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).
