Bluelab Temperature Probe

Temperature Readings That Keep Controller pH Accurate, 3.5 mm Plug

pH readings change with temperature, so a controller needs a reliable temperature input to compensate correctly. The Bluelab Temperature Probe gives Bluelab pH Controllers and Pro Controllers a fast, accurate solution temperature reading. It needs no calibration.

It suits controller owners replacing a damaged probe and commercial users keeping spares for multiple controllers.

Key Features & Benefits

• No calibration required — plug in and read.
• Fast sensor response — tracks solution temperature changes quickly.
• Stainless steel and waterproof — durable body for continuous immersion.
• 3.5 mm connector — on a 2 m / 6.6 ft cable.

Who Should Use the Temperature Probe

Owners of Bluelab pH Controllers or Pro Controllers who need a replacement or spare temperature probe.

About Bluelab Temperature Probe

Bluelab lists this temperature probe as compatible with all Bluelab pH Controllers and Pro Controllers.

Frequently Asked Questions

Which controllers does it fit?

Bluelab lists it as compatible with all Bluelab pH Controllers and Bluelab Pro Controllers.

Why does a pH controller need a temperature probe?

pH readings vary with temperature. Automatic temperature compensation uses this probe's reading to correct pH, and it applies when the temperature probe is in the same solution as the pH probe.

Does it need calibration?

No. The temperature probe requires no calibration.

Where should I place it?

Place it in the same solution as the pH probe, so compensation reflects the conditions the pH probe is measuring.
