Bluelab Conductivity Pen Meter - Measures Conductivity and Temperature

Compact, Accurate EC and Temperature Monitoring in a Pocket-Sized Pen

The Bluelab Conductivity Pen delivers fast, reliable EC and temperature measurement in a waterproof, pocket-sized format. With automatic temperature compensation built in, readings reflect true conductivity regardless of solution temperature. The selectable conductivity and temperature units, backlit LCD display, and hold reading function make it the go-to handheld EC pen for daily nutrient solution checks.

Key Features & Benefits

• Measures conductivity and temperature - Two key parameters for nutrient management in a single compact instrument.
• Automatic temperature compensation - Integrated temperature sensor ensures conductivity readings are accurate regardless of solution temperature.
• Fully waterproof construction - Safe to submerge for accurate reservoir measurements and easy to rinse clean after use.
• Backlit LCD display - Clear readings in low-light greenhouse and grow room conditions.
• Selectable units - Choose preferred conductivity and temperature units to match your nutrient program.
• Hold reading function - Lock the display on the current reading for convenient data recording.
• Calibration optional - Comes pre-calibrated and is ready to use; calibration can be performed as needed.

Who Should Use This

Hydroponic growers, greenhouse operators, and nutrient solution managers who need a quick, portable conductivity check without the bulk of a full-sized meter. Perfect for rapid reservoir checks, tank monitoring, and daily nutrient verification.

Compatibility

Compatible with all hydroponic nutrient solutions. Automatic temperature compensation ensures accuracy across solution temperatures. Includes one AAA replaceable battery. Calibration is optional and can be performed as needed.

Frequently Asked Questions

Does this pen measure pH?

No - the Bluelab Conductivity Pen measures conductivity (EC) and temperature only. For pH measurement, the Bluelab pH Pen or Combo Meter is recommended.

Is calibration required?

Calibration is optional - the pen comes ready to use. Periodic calibration verification with Bluelab 2.77 EC standard solution is recommended for ongoing accuracy.

What does automatic temperature compensation do?

It adjusts the conductivity reading based on solution temperature, so you get a true EC value regardless of whether the solution is warm or cold.

What battery does this pen use?

One AAA replaceable battery is included.
