The Hach Sigma 900MAX Portable Sampler in five key concepts: accuracy, simplicity, flexibility, reliability, and economy.

Easy, menu-type programming uses a large backlit display. Use the Hach Sigma 900MAX sampler to monitor and log rainfall, level, flow, velocity, temperature, pH or ORP, with 12 data logging channels. Depending on model, up to seven external analog signals can also be logged. As many as 116,000 readings may be recorded.

Unique Constant Time / Variable Volume Sampling

The patented Constant Time/Variable Volume sampling method varies sample size in proportion to flow rate. This feature takes regularly timed, proportional samples depending on the flow rate, ensuring that representative samples are taken at even intervals throughout the sampling period.

Field Convertible for Compact or Discrete Sampling

Weighing only 28 pounds (12.7 kg), the 900MAX Portable Sampler is designed for accuracy and convenience. Quickly switch between composite and discrete sampling in the field. Configurable for single- or multiple-bottle applications, it is specifically designed for use in 18-inch manholes.

Reliable Peristaltic Pump Technology

The 900MAX sampler uses a positive displacement peristaltic pump made of corrosion-resistant Delrin® material. While other peristaltic pumps fail to meet EPA1 criteria for representative intake velocity, Hach samplers produce a 3.3 ft./s velocity at3 ft. lift in a 3/8-in. ID intake line.

Advanced Liquid Detection Techniques

The non-contact ultrasonic liquid sensing system guarantees volume accuracy and repeatability. Reduce cross-contamination with a line rinse; the intake is preconditioned with the source liquid prior to collection. In the event that a plugged intake prevents collection, the unit detects the failed attempt and immediately repeats the cycle starting with a high-pressure purge.

Customizable Set Points

Collect samples in response to changing levels of selected parameters—set high and low trip points to immediately collect when a parameter exceeds preset limits.

Easy Data Management Software

Powerful, user-friendly software makes it easy to analyze the data and produce presentation-quality reports for any time period, or generate customized reports integrating sample collections with a variety of parameters.


The Hach Sigma 900MAX Portable Sampler is designed for indoor or outdoor use. No secondary enclosure is required when operated within the specified temperature range. The sampler consists of three main sections—the top cover, the center control system, and the bottle/base section held together by stainless steel latches which serve as the connection point for the optional suspension harness. The lockable top cover protects the controller from extreme weather and unauthorized use.
