Orion Model 130A and 131S Basic Waterproof Conductivity/TDS/Salinity/Temperature Meters
Model 130S Intrinsically Safe (Explosion Proof)
Compatible with USP Regulations
Wide Cell Constant Range for Maximum Compatibility
The Models 130A and 131S are designed for measurement of conductivity, salinity, total dissolved solids and temperature. Wide measurement range allows for a variety of samples. The meters calibrate via cell constant adjustment method. The meters are compatible with two or four electrode cells. Temperature compensation options, such as automatic or manual linear function, and nonlinear function for ultrapure or natural water are available. These meters offer an easy to use interface and GLP features such as cell status and self-diagnostic testing. The Model 131S is intrinsically safe for use in a non-sparking environment. Complete field kit available. Meter warranty is 3 years.
