Page 4: Introduction
Model 88C Instruction Manual Introduction The Model 88C Resistivity Meter measures the resistivity of fluids, slurries, and semisolids according to API recommended practice. Field and laboratory personnel rely on this instrument to evaluate formation characteristics from electric logs. Resistivity is the ability of a material to resist conduction; conductivity is the reciprocal of resistivity. - Page 5 Model 88C Instruction Manual HOT SURFACE! Alerts the operator that there is a hot surface and that there is risk of getting burned if the surface is touched. EXPLOSION RISK! Alerts the operator that there is risk of explosion. 207980...

Page 6: Safety
Model 88C Instruction Manual Safety Safe laboratory practices and procedures should be observed while operating and maintaining the Model 88C. Battery Safety On nine volt batteries, the positive and negative terminals are on the same end, next to each other. If these terminals touch anything metal, such as steel wool, coins, or a paper clip, a short circuit could occur, creating heat, sparks, a fire, or an explosion. -
Page 7: Features And Specifications
Model 88C Instruction Manual Features and Specifications The Model 88C can measure resistivity in three ranges – 0.01 to 2, 0.1 to 20, and 1.0 to 200 ohm meters. The ohm-meter reading can be converted into parts per million sodium chloride (or equivalent calcium chloride, potassium chloride or other carbonate or hydroxyl salts) using the resistivity chart (Figure 4-1). -
