Manufacturer: COLE-PARMER Brand: Cole-Parmer

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 body signal conditioner with non-replaceable lithium battery provides up to five years of operation. Choose unity gain amplifier, differential amplifier, or 4 to 20 mA output to make a looppowered, 2-...

The Combo HI 991404 meter is designed for continuous, high accuracy pH, EC/TDS and temperature measurements. These microprocessor indicators continuously monitor the three most important nutrient parameters in hydroponics, greenhouses and horticultural applications with a single instrument. These indicators feature a large, dual-level, backlit LCD to give you instantaneous readings of pH, EC or TDS and temperature, even from a distance. At startup, these indicators perform a self-check to assure proper working condition. HI 991404 stability indicator and hold features prompt the user when to take the reading and freezes the display for easy and accurate recording. Calibration and temperature compensation is automatic, while the EC/TDS conversion factor and temperature coefficient (ß) are user adjustable for application-specific measurements. These instruments are supplied with an advanced, non-clogging double junction pH electrode and a rugged conductivity probe that will withstand even the most aggressive...
