This Hanna mini controller has been specially designed for water conditioning and growing applications. Compact in size, it can be mounted in confined spaces or even right next to the vat or barrel containing the chemicals. This meter permits automatic control of installations previously checked manually. EC measurements are shown on the display and the multicolored LED continuously indicates if the mini controller is in measurement, dosing or alarm mode. BL 983313 measures in the 0 to 1999 microseconds/cm range. Manual control is particularly useful during maintenance operations, because it permits operators to enable or disable the dosing relay according to need. The overtime control system advices users when the relay is active for too long, helping to prevent over dosage. This model is supplied with mounting brackets, transparent cover and instruction manual. Range: 0 - 1999 microseconds per centimeter. Resolution: 1 microsecond per centimeter. Accuracy: +/-2 percent F.S. Calibration manual with CAL trimmer. Setpoint adjustable from 0 to 1999 microsecond per centimeter. Overtime adjustable, typically from 5 to approx. 30 minutes. 115/230V Power supply. Measures 3-3/32" Length by 1-57/64" Width by 3-11/16" Height.

The Hydrometer is an instrument which is constructed on the Archimedes principle that a solid body displaces its own weight of the liquid in which it floats. Hydrometers can be divided into two general classes; namely for liquids heavier than water and for liquids lighter than water. The base hydrometer scale is Specific Gravity, in which distilled water equals 1.000 as the initial point. Liquids lighter than water are scaled below 1.000 specific gravity and liquids heavier than water are scaled above 1.000 specific gravity. Hydrometers are usually calibrated at 60°F/60°F. To determine the density of a liquid, the liquid should be at 60°F. If the temperature varies, the liquid will either contract or expand, depending upon the temperature. Where there is a variation from the standard 60°F, corrections must be applied to the hydrometer reading. To assure proper corrections, a separate accurate thermometer should be used, or a hydrometer in combination with a thermometer, which is sometimes referred to as a "thermohydrometer."

These cartridge-style electrodes are the next generation of the well-proven Cole-Parmer cartridge electrodes. The userconfigurable, plug-and-play nature of the system provides the ultimate in flexibility and versatility-purchase as few, or as many components needed for your application. If your application needs later change, single components can be added or subtracted, saving time and money of having to replace an entire system. The reference system of the ERP-series has been enhanced with severe-duty reference gels to provide protection against thermal and chemical breakdown. In addition, a complex double-junction pathway protects the reference cell from contamination from heavy metals, sulfur, iodine, or proteins. Systems are configurable to interface with virtually any make or model o Fully submersible, PPS construction adapters to connect cap cable to electrode. Models available with or without ATC elements, and for submersion or in-line installations User-configurable self-cleaning, flat-surfaced electrodes for almost any application. Extended Reference Path (ERPTM) technology for long life and stability. Modular plug-and-play design. Optional plug-in electronics produce amplified or mA signals
