GF Signet - pH & Conductivity Monitors

2774 Series pH Electrodes

The +GF+ SIGNET 2774 – 2777 pH and ORP Electrodes feature a unique foul-proof DryLoc™ connector with gold plated contacts designed specifically for use with the +GF+ SIGNET 2750 and 2760 preamplifiers, sensor electronics, and connectors.

2714 Series pH Electrodes

+GF+ SIGNET Conductivity/Resistivity Electrodes are designed to provide versatile installation and accurate sensing across a very broad dynamic range. Coupled with +GF+ SIGNET patented measuring circuitry, a three Technical Features decade measurement range reading is achieved without the need for troublesome electrode platinization.

2720 Pre Amp

Pre-amplification is required to protect the relatively weak output signal of pH & ORP electrodes from a wide variety of electromagnetic interference common in industrial environments. The +GF+SIGNET 2720 Twist-Lock Pre-amplifier is installed locally, at the sensing point, to maximize this protection while allowing cable extensions up to 120 m (400 ft.).

The 2839-2842 DryLoc™ Conductivity / Resistivity Electrodes are available in four cell constants from .01 to 10.0, and are suitable for a wide variety of applications from high purity water quality monitoring to demineralizer regeneration.

8850 Panel Mount Conductivity Monitor

The +GF+ SIGNET 8850 Conductivity / Resistivity Transmitter is designed for broad application and ease of setup and use. The unit can be used for conductance, resistance, or TDS signal transmission and display.

8860 Conductivity Monitor

The +GF+ SIGNET SIGNET 8860 Dual Channel Conductivity/Resistivity Controller is a two-channel input device equipped with three scaleable 4 to 20 mA outputs and four programmable relays.

2850 DriLoc Sensor

The 2850 Conductivity/Resistivity Sensors provide two-wire 4 to 20mA output without the expense of local display and other luxuries available in full-featured transmitters. Eight 4 to 20mA output ranges for each electrode cell constant, plus the ability to invert each range, are selectable by the user in the field.
