THROUGH THE Cultivator's LENS Product Evaluation

  • You are managing an inline dosing system because standard reservoir probes cannot handle line pressure without failing
  • You are adding automated pH monitoring to your fluid lines because manual spot-checking leaves too many gaps between readings

  • The three-quarter inch thread mounts in any direction so you can fit it into tight dosing lines without awkward angles
  • The double-junction design delivers reliable readings in flowing nutrient solution rather than drifting under pressure
  • The three meter cable gives you plenty of slack to route around pumps and valves without stretching the connection

  • Growers running pressurized dosing lines say they stopped worrying about blown reservoir probes once they switched to this inline unit
  • Operators who integrated the probe into their monitoring setup say they finally catch pH drift before it impacts the root zone

Bluelab pH Probe Inline -  Replacement Probe for Guardian Monitor Inline

Standard pH probes aren't built to handle line pressure, making them a poor fit for inline dosing systems where a reservoir probe simply won't hold up. The Bluelab pH Probe Inline solves this with a 3/4" thread designed for inline mounting in any direction, rated to withstand up to 100 psi (7 bar) — built as a direct replacement probe for the Bluelab Guardian Monitor Inline.

A double-junction design and standard BNC connector keep it compatible with BNC-connection devices like the Bluelab Combo Meter, while a 3-metre (9.8ft) cable gives you flexibility in routing around pumps, valves, and dosing lines. Fully waterproof construction holds up to constant exposure in a pressurized system.

A KCl-filled storage cap keeps the probe hydrated between uses; for best results, maintain the cap with Bluelab KCl Storage Solution to protect accuracy and extend its working life in demanding inline installations.
