Bluelab Combo Meter (pH, EC & °C)

Bluelab Indoor Grow Water pH, EC and Temperature Meter

The Combo Meter (Ph, EC and ºC) Bluelab integrates the critical information that makes the difference between correct irrigation and problems of lockout or deficiencies. It allows you to measure pH, EC, PPM500, PPM700 and temperature in ºC or ºF, with over and under range indicators to instantly detect deviations.

Includes replaceable pH probe (Bluelab pH Probe), automatic shut-off function and low battery warning (works with 2 AAA batteries included).

Switching between parameters is done with a button, pH calibration is simple and conductivity/temperature do not require calibration.

In indoor grow installations—whether hydroponics, coco or soil—this meter reduces errors, homogenizes recipes and helps maintain an optimal pH range that enhances nutrient uptake.

The clear reading on the large screen avoids doubts during daily adjustment of tanks, recirculations or drip irrigations.

Maintenance is simple: keeping the probe cap slightly moist with storage solution extends lifespan and preserves accuracy.

Thanks to its compact design and light weight, it moves easily around the grow room, cabinets or work tables.

It is a key tool among grow meters and fits both in small cabinets and in indoor accessories for large professional rooms.

Indoor Grow Combo Meter (Ph, EC and ºC) Bluelab

In indoor growing, every parameter matters. This meter allows you to set a target pH, check EC according to the stage (growth, transition and flowering) and adjust the temperature of the solution to improve absorption. It helps prevent lockouts, accumulated salts and pH imbalances that hinder performance in cannabis cultivation. In recirculating systems, drain-to-waste or RDWC tanks, continuous control of these values stabilizes the root environment and increases crop consistency.

What is the Combo Meter (Ph, EC and ºC) Bluelab for?

It is used to quickly and accurately measure the three pillars of irrigation: pH (acidity/alkalinity), EC (strength of the nutrient solution) and ºC (temperature of the mix). With this data, fertilizers are adjusted, corrected with acids/regulators and the irrigation frequency is defined. Immediate reading in PPM500 or PPM700 makes it easy to work with manufacturer tables. The instrument alerts when a value goes out of the recommended range, allowing you to act before symptoms appear on leaves or roots.

Indoor Grow Tool Combo Meter (Ph, EC and ºC) Bluelab

As a work tool, it stands out for: large screen for easy reading, real portability, replaceable pH probe and automatic shut-off. It does not need calibration for EC/temperature, which simplifies daily use. The push-button pH calibration and calibration indicator reduce adjustment errors. It includes a low battery indicator to avoid running out of power during a measurement. All in all, it is a perfect ally for online grow shops, grow schools and technicians who calibrate several tanks during work shifts.

How is the Combo Meter (Ph, EC and ºC) Bluelab used?

1) Preparation: turn on, rinse the probes with clean water, dry with paper without excessive rubbing. Check AAA battery charge.
2) pH Calibration: follow the push-button calibration method using buffers; the device itself guides with a calibration indicator. For EC and temperature no calibration is needed.
3) Measurement: immerse the probe in the tank or sample; select between pH, EC/PPM or ºC/ºF with the button. Wait for the reading to stabilize and record values.
4) Adjustments: correct pH with regulators and fine-tune EC by adding nutrients or diluting with water. Check that the water temperature remains within a suitable range for roots.
5) Maintenance: clean after each session; keep the pH probe cap moist with storage solution. Avoid distilled, deionized or reverse osmosis water in the storage cap.
