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
