Ph-EC-Temp. Water Master Meter is a portable multiparameter meter that centralizes pH, EC, and temperature in a single tool. With microprocessor, tilted LCD screen, ATC, and IP57 housing that floats (not submersible), it streamlines controls in indoor cultivation of cannabis plants.

The Ph-EC-Temp. Water Master Meter is optimized for fast and accurate measurements of irrigation water in hydroponics, coco, and soil. The device simultaneously displays pH + temperature or EC + temperature depending on the installed probe; the microprocessor recognizes the module and automatically adjusts the reading.
The automatic temperature compensation (ATC) corrects the thermal effect on the values, ensuring precise decisions when preparing nutrient solutions.
Its IP57 protected housing resists splashes and floats on water for added safety (not designed for immersion).
It features a battery indicator, auto-off after 10 minutes, and easy electrode module replacement to switch between parameters.
Key specifications: pH range 2–16.0 with resolution 0.01 pH and accuracy ±0.1; EC range 0–2000 µS with resolution 10 µS/cm and accuracy ±2% FS; temperature range 0–90 ºC with resolution 0.1 ºC and accuracy ±0.2.
Compact dimensions 3.35 × 17 cm and powered by 4 AAA batteries (1.5 V) make it a practical ally among grow meters and indoor accessories.
In indoor grow setups with multiple irrigation lines, this meter standardizes recipes, reduces salt blockages, and increases consistency in cannabis cultivation.
Available at Hydroponics Blanes, online grow shop, and Grow Shop in Spain with discreet shipping and technical advice from a trusted Grow Shop.
In indoor growing, keeping pH in range and EC according to each phenological phase determines nutrient uptake. Ph-EC-Temp. Water Master Meter allows you to validate base water, adjust solutions, and check reservoir temperature, a variable that influences oxygenation and pH stability. Fast readings at mixing tables, RDWC tanks, or drains to act before foliar symptoms appear.
It is used to accurately measure pH, electrical conductivity (EC), and temperature of irrigation water. With this data, it is easy to decide whether to dilute, reinforce nutrients, or adjust with pH regulators. The combined pH/EC/ºC reading speeds up diagnostics and helps maintain stable nutrition in cannabis plants.
As a work tool, it stands out for its ATC, easy-to-read tilted screen, splash-resistant IP57, and interchangeable electrode modules that the microprocessor instantly recognizes. The portable format, stable electronics, and auto-off improve operation in rooms and tents. A must among grow meters to keep recipes consistent in indoor grow setups.
1) Preparation: rinse the tip with clean water and dry with paper without rubbing. Check AAA battery charge.
2) Parameter selection: install the corresponding module (pH or EC). The device identifies the electrode and displays pH + ºC or EC + ºC on the LCD screen.
3) Calibration: for pH, use buffers 7.0 and 4.0/10.0 according to strategy; for EC, standard solution appropriate to the working range (e.g., 1413 µS/cm). Repeat calibrations periodically.
4) Measurement: immerse the tip in the tank or sample; wait for stabilization. Record values and adjust recipe according to phase objectives (growth, transition, flowering).
5) Maintenance: rinse after each use; change module when stabilization time increases or calibrations require large corrections. Keep away from impacts and total immersion (housing IP57 not submersible).
The price matches professional features: pH/EC/ºC measurement, ATC, microprocessor with probe recognition, IP57, auto-off, and tilted screen. Check packs with buffer solutions and conductivity standards at Hydroponics Blanes, a benchmark Grow Shop in Spain for indoor accessories.
Available at Hydroponics Blanes, trusted Grow Shop, and online grow shop with discreet shipping. Advice to integrate the meter into irrigation routines, choose calibration solutions, and define ranges by stage in cannabis cultivation.
Anyone seeking comprehensive control in a portable format will find a reliable ally in the Ph-EC-Temp. Water Master Meter: clear readings, ATC for interpreting values, and robust IP57 design that floats, perfect for stabilizing recipes in indoor grow projects with the support of Hydroponics Blanes and logistics from a trusted Grow Shop.
