Point Four Systems Inc.

Pentair Point Four

Point Four Systems specializes in the design, manufacture, and supply of systems for the measurement, control, and diffusion of oxygen and other gases in water. We manufacture a range of microbubble ceramic diffusers, oxygen injection systems, and water quality monitor and control systems. Our products include a Monitoring and Control System with customizable PC program with trending, logging, and web enablement. New to our line are a handheld Total Dissolved Gas Pressure Meter, and a Dissolved CO2 meter.

PT4 Tracker – handheld meter with optional Smart Probes (TGP, pH, Conductivity/Salinity, ORP/REDOX, and Temperature)

PT4 Tracker

  • Originally designed for measuring Total Dissolved Gas Pressure to prevent Gas Bubble Trauma in fish, it is now offered with 4 different PT4 Smart Probes.
  • Optional Datalogging with PC Software
  • Rechargeable battery with optional external battery attachment for long-term monitoring
  • Optional wireless communication
  • User defined primary display screen

PT4 Smart Probes

  • Temperature and barometric pressure compensated.
  • Store calibrations and parameters within the probe’s built-in memory, allowing probes to be changed without meter calibration every time.
  • One meter for all probes purchased – reduces costs
  • Datalogging capable and external battery connection.

Dissolved CO2 Meter – handheld or stationary monitoring system

  • Is not affected by other dissolved substances because it measures free dissolved CO2 gas directly.
  • Easy to calibrate, with long calibration intervals.
  • No regular maintenance.

NEW Handy Polaris – handheld dissolved oxygen meter

  • Temperature and barometric pressure compensated.
  • Automatic calibration.
  • Extremely long battery life.
  • Comes with four language options: English, Français, Espa͂nol, and Deutsch.

PT4 Monitor – customizable monitoring and control system for managing water quality parameters.

  • Up to eight channels can be displayed and monitored simultaneously, each with its own warning light and audio alarm, as well as a common alarm, for out of range conditions.
  • Compatible with any sensor producing a mV or 4-20 mA output to monitor dissolved oxygen, temperature, pH, salinity, total dissolved gas pressure, and conductivity.
  • Built-in datalogging/transfer and real-time trending (with optional software)
  • Optional remote paging for a distance up to 2.2 km, auto-dialer, and remote PC connection.

Oxygen and CO2 Diffusers – options to suit every application and budget.

Microbubble Diffusers

  • Efficient – uses less oxygen and fewer diffusers
  • Robust construction
  • High absorption rates

Wedge-Lock Diffusers

  • Modular system of diffusers for maximum versatility.
  • Up to 8 “Twist and Lock” together

Econo Diffusers

  • Economical
  • Easy to install
  • Flat design minimizes rising air bubble coalescence

Porous Hose

  • Flexible, low-cost option
  • Releases gas uniformly along its entire length
  • Very durable
  • Low bubbling pressure

Point Four’s success is built on our willingness to go that extra mile in understanding our customer’s requirements, supplying unbiased technical consultation and thorough after-sales support.
