    The Signet 4630 Chlorine Analyser System is an integrated all-in-one system designed to measure free chlorine. The 3-4630-21 chlorine panel with the optional pH sensor is used to accurately calculate free chlorine in applications that have varying pH values (±0.20 pH units). In applications where the pH is stable, the pH sensor is not required and the pH value is manually entered into the transmitter to calculate the chlorine levels. (-20 version). The unique integrated clear flow cell combines sensors, flow regulator, filter and variable area flow indicator in one compact unit. An integrated flow regulator with removable filter accepts inlet pressures of 1 to 8 bar (15 to 120 psi), while maintaining constant flow and minimal pressure to the sensors. Water flows vertically into sensor tip eliminating bubble entrapment. The flow cell is designed to maintain a minimum amount of water to ensure sensors stay submerged, even when the system and flow is turned off. The Signet 4630 Chlorine Analyser System allows quick setup and easy installation and is supplied with a 100-240 VAC power supply, two 4 to 20 mA outputs and two dry contact mechanical relays. The flow cell accommodates two sensors: one chlorine and an optional pH sensor.

    • Built-in flow regulator maintains constant flow and pressure to the sensors regardless of inlet pressure
    • Reagent free measuring
    • Complete panel system allows for quick and easy installation

    The Signet 4150 Turbidimeter system provides accurate and reliable compliant water quality monitoring for municipal and industrial applications.

    • Ultrasonic cleaning option insures long and steady on-line measurement
    • Compatibility: 8058 i-Go Signal Converter
    • EPA compliant per U.S. EPA 180.1 or ISO 7027
    • Programmable 4-20 mA output•Simple and easy one-unit installation with built-in pressure regulator
    • Easy access for wiring and maintenance
    The Signet 4150 Turbidimeter system provides accurate and reliable EPA-compliant water quality monitoring for municipal and industrial applications. The 4150 measures turbidity via a 90 degree light which reflects particles as they flow through the small volume, low flow glass cuvette. Air bubbles are eliminated in the cuvette by adjusting the backpressure valve on the outlet tube. The cuvette is located in a watertight dark chamber for continuously accurate on-line measurement. A replaceable desiccant pack provides stable environment to ensure reliable measurements. Simple and fast calibration can be accomplished in under five minutes by placing the glass cuvette from the measuring chamber into the cuvette holder, while the inlet and outlet tubing is still connected. The inexpensive calibration standard allows for dry and multiple system calibrations without mixing chemicals. After calibration, the unit is up and running with a simple insertion of the glass cuvette into the measuring chamber. The 4150 is available in two measuring ranges. The 0 to 100 NTU/FNU version is for low range applications such as drinking water. The 0 to 1000 NTU/FNU range can be used for various applications including raw water and wastewater.

  • sig8630

    The Signet 3-8630-3P ProcessPro Chlorine Transmitter simultaneously displays free chlorine and pH levels on a bright LCD backlight display. The 8630 transmitter has two 4 to 20 mA outputs that can be programed to transmit chlorine, pH or temperature information to a data collection device. Two dry-contact mechanical relays can be used to deliver an alarm signal or activate a chlorine dosing system. Programming is simple and easy with Signet’s standard 4 button keypad. The menu option allows the use of an optional pH sensor to accurately calculate free chlorine level or select “Manual pH input” and enter the applications stable pH level to determine free chlorine levels.
