8750-2 Manual
8750-3 Manual

The Signet 8750 pH/ORP Transmitter is designed for broad application and ease of setup and use. The unit auto-configures for either pH or ORP use when connected to Signet pH or ORP sensors. Multiple mounting options allow for installation best suited to your particular application. The automated "Easy-cal" menu features automatic buffer recognition for mistake proof pH or ORP sensor calibrations. Intuitive software and the four button keypad arrangement make it easy to access important information such as pH or ORP, mV input, temperature, calibration, relay set-up menus and more.

Features:

  • Automatic temperature compensation (pH)
  • Display in °C or °F
  • Hold and Simulate functions
  • Integral or remote mounting
  • Relay options
  • Output scalability
  • Dual output option allows temperature and pH signal transmission
  • 2 x 16 character dot matrix LCD
  • Chemical resistant enclosure and self-healing window
  • Large pushbuttons
  • Clearly marked terminal labels
Applications:
  • Neutralization systems
  • Heavy metals recovery
  • Plating control
  • Scrubber control
  • Pool and spa control
  • Environmental study
  • Water treatment
  • Water quality monitoring
  • Waste treatment
  • Disinfecting

5700 ProPoint® pH/ORP Monitor

Data Sheet
5700 pH Manual
5700 ORP Manual

The Signet 5700 pH/ORP Monitor is a versatile and intelligent instrument that recognizes the type of sensor connected, either Signet pH or ORP Electrode, then automatically sets itself for the corresponding display and functionality. Also, during "Easy Cal" operation, the monitor automatically recognizes standard buffers/test solutions thereby shortening and simplifying routine calibration procedures. Two programmable relays and one scaleable 4 to 20 mA output are included, and the four-button keypad arrangement with intuitive software design is very user-friendly. The monitors require 12 to 24 Volts, AC or DC, and can be used with the Signet 2720 pH/ORP Preamplifier and Sensor system, or with sensors from other manufacturers by using the 2721 Preamplifier. Several useful accessories are available, including the optional Rear Cover Kit used to extend the NEMA 4X/IP65 integrity of the front panel to the entire enclosure.

Features:

  • Simultaneous pH and Temperature Display
  • Simultaneous ORP (calibrated) and Input (raw) mV Display
  • Scaleable 4 to 20 mA Output
  • Two Programmable Relays
  • Dual Proportional Control Capability
  • Temperature Compensation
  • Automatic Sensor Recognition
  • "Easy-Cal" Simplifies Routine Calibration
  • Analog and Digital Display

Applications:

  • Water & Wastewater Treatment
  • Neutralization
  • Scrubber Control
  • Effluent Monitoring
  • Surface Finishing
  • Heavy Metal Removal and Recovery
  • Toxics Destruction
  • Sanitization Systems
  • Commercial Pools & Spas
  • Aquatic Animal Life Support Systems
  • Process Control

pH/ORP Buffer Solutions

pH/ORP Buffer Solutions

Data Sheet

The Signet pH buffers are ideal for many calibration requirements. The liquid solutions are conveniently packaged in one pint bottles; the powder pillows are packaged in low weight, single-use containers which can be mixed with water. All pH buffers are color coded for easy identification; 4.01 pH is red, 7.00 pH is yellow, and 10.00 pH is blue.

The pH buffers are traceable to NIST standards and certificates are available upon request. They are accurate to within ± 0.01 pH units @ 25 °C and have long term stability.

These solutions are temperature sensitive and are provided with temperature correction values for the most accurate calibration. For applications that require ORP calibration, the pH 4 and pH 7 buffers can be mixed with quinhydrone powder for the correct measurement values of 87 mV and 264 mV respectively.

Features:

  • NIST Traceable
  • Easily identifiable color
    coded buffer solutions
  • Liquid or powder
    versions
  • Temperature
    compensated values
  • Kits for easy use
