Pyxis LT-739 Ultralow Turbidity Sensor (Warm White Light, Mid Range)

Model:
LT-739
Brand:
Pyxis Lab

The Pyxis LT-739 is a mid-range ultralow turbidity sensor using warm white light (3200K) illumination, built for resolution and accuracy beyond a standard process turbidimeter. It measures 0.000-40.000NTU with 0.002NTU resolution and 2% accuracy to EPA 180.1, with dual 4-20mA analog outputs plus RS-485 through an 8-pin connector.

Mid-range precision — 0.000-40.000NTU range with 0.002NTU resolution and 2% accuracy to EPA 180.1
Dual 4-20mA outputs — plus RS-485 via an 8-pin connector for flexible integration
Mid-range precision — 0.000-40.000NTU range with 0.002NTU resolution and 2% accuracy to EPA 180.1

Description

The Pyxis LT-739 is the mid-range variant of the ultralow turbidity sensor family, using warm white light (3200K) illumination to deliver resolution and accuracy beyond a standard process turbidimeter. It measures across a 0.000-40.000NTU range with 0.002NTU resolution and 2% accuracy, tested to the EPA 180.1 method.

It communicates through dual 4-20mA analog outputs plus RS-485 via an 8-pin connector, allowing straightforward integration with existing control and monitoring systems.

The mid-range span makes it a fit for process applications that fall between the ultra-fine low-range LT-737 and the broader-range LT-736, where the target turbidity window typically sits in the tens-of-NTU range.

Why Use This

Balanced Range and Precision

Covers 0.000-40.000NTU with 0.002NTU resolution and 2% accuracy to EPA 180.1, suited to mid-range low-turbidity monitoring.

Flexible Signal Output

Dual 4-20mA analog outputs plus RS-485 via an 8-pin connector support integration into existing systems.

Applications

  • Mid-range process turbidity monitoring — tailored to the 0-40NTU window common in process control
  • Regulatory turbidity reporting — accuracy referenced to EPA 180.1
  • Treated water clarity verification — precision beyond standard process turbidimeters
