Signet Analytical Instruments - pH, ORP, Conductivity and Resistivity
SmartPro pH / ORP transmitter - Offers high visibility display - 4-20mA output signal with plug-in module for control relays. HART module available.
ProPoint™ pH controller - ORP controller - Offers two relay for control and 4-20mA output signal for recorder.
Direct Output Sensors Transmitter - pH and ORP sensors provide analog signals without a controller for the user who required only input signals.
SmartPro Transmitter - Series 9900
This is a single channel multi-parameter device that is field convertible to accept sensor inputs or other 4-20mA signal and provide a variety of display units. A series of lights form a "Dial-Type" display for easy visual reading. The display has a visible distance from as much as 5 times the as the instruments that it replaced. Analog signal output (4-20mA) provides integration with recorders or other instruments. The 9900 is a single channel input unit. Field plug in relay module and Hart communications module are available for the panel mounted units to further expand the usage of the instrument.
The 9900 Transformer is use for Flow, pH/ORP, Conductivity/Resistivity, Temperature, Pressure, Salinity or Level. The internal software is configured when the input electrode is connected. The 9900 is available in a panel or field mount case. 1/4 DIN panel cutout. 9900 Data Sheet
pH / ORP Mode
The base unit (3-9900-1 or -1P) provides a digital indication of pH (or mV in ORP mode) and temperature. Field plug in relay module and Hart communications module are available for the panel mounted units to further expand the usage of the instrument. Use 2750 sensor electronics (per-amp) with the 9900 SmartPro controller. pH / ORP sensors
Conductivity / Resistivity Mode
The base unit (3-9900-1 or -1P) with the Conductivity/Resistivity module provides a digital indication of conductivity and temperature. Selectable unit displays are selected to provide compatibility with range selected sensors. Analog signal output (4-20mA) provides integration with other instruments. Conductivity sensors
for pH or ORP
The SIGNET 5700 pH/ORP Monitor features operational simplicity as the most noticeable feature. The software automatically identifies the signal from the sensor and presents the correct operating menu for pH or ORP applications. The analog dial provides easy visibility while the alphanumeric LCD shows precise pH and temperature values. Simple push-button programming displays millivolts, pH, and temperature values. Calibration menus feature a unique "Easy-Cal" automatic calibration, including buffer recognition of the most commonly used pH and ORP values. The 5700 provides analog and digital display, digital temperature display, two control relays and analog output for process control or recorder.
The SIGNET 5800CR Monitor is similar to above for conductivity and resistivity. Automatic temperature compensation for accurate readings. The analog dial provides easy visibility while the alphanumeric LCD shows precise conductivity and temperature values. Simple push-button programming displays for dual alarm and 4-20mA output.
- 2750 pH/ORP Sensors provide two-wire 4 to 20mA loop output for pH and ORP measurements, without the expense of local display and other luxuries available in full-featured transmitters. Pre-amplification is built-in, reducing system costs while ensuring absolute signal integrity up to 1,000 feet. pH sensors feature automatic temperature compensation. Also use with 8900 and 9900 controllers.

Specifications for conductivity/Resistivity sensors
Note: A very limited number of replacement units MAY be available. The electrodes can be used with the new units however a replacement PRE-AMP will be required.
Obsolete - Intelek-Pro
Signet 9030 pH controller uses plug-in cards to
customize for your requirements. Output cards may provide dual alarm or on-off
condition points, dual proportional pulse controls for metering pumps and two analog
outputs. The large LCD display indicates the pH condition or temperature.
Temperature compensation provides accurate reading from 32 to 212 F. The front
keypad accesses card (or relay) status, calibration, and sensor condition.
