DW-2100P Features
Pyxis Lab’s advanced research and development sensor technologies to achieve highly accurate and stable
measurement of Turbidity, Free Chlorine, pH and Temperature.
Pyxis LT-739 (EPA) and LT-739B (ISO) ultra-low resolution turbidity sensors offer a detection light source
using warm white LED in 90-degree surface scatter format in accordance with USEPA 180.1 standards or
Infra-Red 860nm in accordance with ISO-7027.1 standards. The turbidity sensors are mounted in the
unique Pyxis FR-200 dual sensor flow reservoir enabling the highest resolution possible of 0.001NTU
with unmatched stability. The LT-739 and LT-739B offers simple calibration via the Pyxis L T- SOLID-
CAL Solid State Turbidity Calibration Kit (no Formazin needed) or the Pyxis L-CAL Portable Liquid
Turbidity Calibration Kit (uses 500mL per calibration).
Pyxis ST-765SS-FCL three-parameter composite sensor is used for the measurement residual free chlorine,
pH and temperature in compliance with USEPA 334.0 and ISO-7393 guidelines. The sensors advanced PCB
offers built-in temperature and pH parameter compensation (up to pH 9.0) algorithms eliminating the need
for a supplemental pH sensor and controller. Unique Bare-Gold electrode technology for residual chlorine
measurement eliminates membranes and electrode solution replenishment commonly associated with
conventional sensors. The ST-765SS-FCL has a uniquely designed flat bubble pH electrode design for
reduced fouling potential. Reduce your maintenance and cost versus colorimetric chlorine measurement or
conventional electrochemical sensors by utilizing Pyxis replaceable Electrode Head (EH-765) for this sensor
allowing for years of reliable service. The ST-765SS-FCL may be calibrated in-situ after cleaning via DPD Free
Chlorine wet chemistry test measurement of active sample.
Pyxis FR-200 Dual-Sensor flow reservoir provides sample calming for dissipation of air-bubbles and
settling of suspended solids, foam or other impurities commonly observed in drinking water influent
with a recommended flow range of 600–1,000mL/minute. This unique flow reservoir design results in
the highest level of turbidity resolution on the market and greatly extends the maintenance cycle of the
sensor while providing a large buffer capacity to mitigate pressure fluctuations. The minimum inlet pressure
of FR-200 flow reservoir is only 7.5 psi (0.05mpa) making it highly suitable for the end of pipe networks and
secondary supply influent sampling.
Both sensors offer a self-cleaning flat electrode design making them easy to maintain and clean.
Simple sensor removal and replacement. Both sensors are connected to the display/data logger via RS-485
Modbus (RTU) allowing for integrated sensor calibration interface and diagnostics within the display touch
screen.
Convenient and simple to install Back-Panel (DW-2100P) for rapid and easy installation. Truly a plumb
and power to go platform with intense factory setup, testing and sensor calibration prior to shipment.
Touch screen display/data logger interface with sensor calibration integrated. Display/data logger offers 2x
4-20mA I/O as well as RS-485 and TCP-IP with remote diagnosis and parameter adjustment. Pyxis
CloudLink
TM 4G Gateway version available.
