Probes Are Consumables, Not Hardware

A controller is only as accurate as the probe feeding it. pH and ORP probes drift as their reference junction ages, and most need replacing every one to two years no matter how well you look after them. Calibrating regularly tells you when a probe has stopped responding properly — and calibration fluid has a shelf life of its own.

What You'll Find Here

  • Replacement probes — pH, ORP, conductivity and temperature, including double-junction types suited to saltwater.
  • Calibration solutions — pH and conductivity standards, plus a stirrer for consistent readings.
  • Probe holders and racks — magnetic mounts and multi-probe organisers to keep probes at a steady depth in the sump.
  • Controller displays and dosers — compact display units and dosing pumps that pair with a wider system.

Buy calibration fluid in step with the probe it serves, and calibrate to a schedule rather than waiting for a suspicious reading. Questions on compatibility? Email info@jlaquatics.com.

J&L Aquatics was formed in December 1997

Our business was started from our love of the aquarium hobby. We at J&L Aquatics felt that the Canadian aquarist should have the option to purchase top quality supplies, equipment and livestock other than the generally over priced local retail stores.
