Pyxis DW-2100P-US Chlorine & Turbidity Analyzer Panel

The Pyxis DW-2100P-US is a pre-plumbed, panel-mounted analyzer for drinking water that continuously measures ultra-low turbidity, free chlorine, pH and temperature on one sample stream. It combines the LT-739 turbidity sensor (warm-white LED, EPA 180.1) with the membrane-free, bare-gold ST-765SS-FCL chlorine / pH / temperature sensor in an FR-200 flow reservoir with rotameter, all feeding a 7-inch industrial touchscreen with a built-in data logger.

Delivered as a turn-key panel, it needs only sample, drain and power connections. Outputs include 4–20 mA, RS-485 Modbus RTU and Modbus TCP over Ethernet, with an optional CloudLink 4G gateway on the “-G” version. The membrane-free chlorine electrode removes reagent and membrane consumables from routine maintenance, and the electrode head is field-replaceable.

Four parameters on one panel — turbidity, free chlorine, pH and temperature
Ultra-low turbidity 0.001–10 / 10–40 NTU, ±0.005 NTU or 2% below 10 NTU (EPA 180.1, warm-white LED)
Free chlorine 0.01–5.00 ppm, membrane-free bare-gold electrode with pH compensation to 9.0
7″ industrial capacitive touchscreen with 4 GB data logger (up to 1 million records)
4–20 mA, RS-485 Modbus RTU and Modbus TCP outputs; optional CloudLink 4G (-G version)
Turn-key panel with FR-200 flow reservoir and rotameter — sample, drain, power and go
Field-replaceable electrode head; no reagents or membranes for chlorine
IP65 display / IP67 sensors; CE / RoHS

Drinking-water treatment plant effluent monitoring
Distribution-network and reservoir water quality
Secondary supply and booster stations
Filter effluent and membrane-permeate turbidity
Pool, spa and decorative water
Regulatory compliance reporting (EPA 180.1 / 334.0)
