Pyxis ST-735-NT Inline Turbidimeter (Ultra High Range, No Tee Assembly)

Model:
ST-735-NT
Brand:
Pyxis Lab

The Pyxis ST-735-NT is the sensor-only version of the ST-735 inline turbidimeter, built for process and treated water clarity monitoring across an ultra-high range of 0-10,000NTU. It ships without the tee assembly kit for installations that already have mounting hardware in place, and provides 4-20mA analog and RS-485 Modbus outputs via a 7-pin connector.

Sensor-only configuration — no tee assembly kit included, ideal when mounting hardware is already installed
Dual output — 4-20mA analog and RS-485 Modbus via a 7-pin connector
Sensor-only configuration — no tee assembly kit included, ideal when mounting hardware is already installed

Description

The Pyxis ST-735-NT is the sensor-only version of the ST-735 inline turbidimeter, built for the same ultra-high 0-10,000NTU clarity monitoring of process and treated water but supplied without the tee assembly mounting kit. It’s intended for sites that already have compatible mounting hardware installed, reducing cost and avoiding duplicate hardware on replacement or expansion projects.

Like the full ST-735, it delivers continuous inline readings through 4-20mA analog and RS-485 Modbus outputs via a 7-pin connector, keeping the same integration path into control and SCADA systems.

This configuration suits engineers standardizing on the ST-735 sensing element across multiple installation points where tee fittings are already in place.

Why Use This

Cost-Effective for Existing Installations

Ships as sensor-only without a tee assembly kit, avoiding redundant hardware costs where mounting is already in place.

Wide Measurement Range

Covers turbidity readings up to 10,000NTU for heavily loaded process streams.

Applications

  • Process water monitoring — continuous inline clarity tracking where mounting hardware already exists
  • Sensor replacement/standardization — swapping in a matching ST-735 sensing element across multiple points
  • Heavily loaded streams — ultra-high 0-10,000NTU range for high-turbidity process water
  • SCADA/control integration — 4-20mA and Modbus outputs for supervisory monitoring

FAQ

What’s the difference between the ST-735 and the ST-735-NT?

The ST-735-NT is the sensor-only version — it ships without the tee assembly mounting kit included with the standard ST-735, for use where mounting hardware already exists.

What turbidity range does it measure?

It covers the same ultra-high range as the ST-735: 0-10,000NTU.

How does it output data?

Via 4-20mA analog and RS-485 Modbus through a 7-pin connector, for integration with existing control or SCADA systems.

Can I use this if I don’t already have a tee fitting installed?

The ST-735-NT does not include the tee assembly kit, so it’s intended for sites where compatible mounting hardware is already in place; otherwise the standard ST-735 would be the appropriate choice.
