PH/EC METERS

Milwaukee MW804: lab-grade precision for serious indoor growers

Mastering your nutrient solution drives 80 % of your final yield. The Milwaukee MW804 combo meter measures the four essential parameters of your water in a single dip: pH, electrical conductivity (EC), total dissolved solids (TDS) and temperature. Engineered for the demands of professional hydroponics, it brings benchtop reliability into a rugged pocket format — selected by BloomLED for growers who leave nothing to chance.

Why the MW804 stands out

🌱 Four readings, one motion

No more juggling separate devices. Dip the probe and read pH, EC, TDS and temperature instantly on the wide LCD screen. A real time-saver when you monitor several reservoirs or grow trays daily.

🔬 Lab-grade precision in your pocket

±0.1 pH and ±2 % on EC: tolerances comparable to benchtop meters. Automatic Temperature Compensation (ATC) corrects thermal drift for reliable readings, summer or winter, in any growroom.

⚙️ Easy calibration, kit included

Three buffer sachets ship in the box: pH 4.01, pH 7.01 and EC 1413 µS/cm solution. A two-point pH calibration ensures accuracy across every cultivation phase, from cloning to flowering.

🌊 Rugged build for daily growroom use

Splash-resistant housing and a combined pH/EC/temperature probe designed for intensive use. Perfect for hydroponic systems, aquaponics, recirculating nutrient solutions or coco/soil cultivation.

🔋 Long-lasting autonomy

Four LR44 batteries (included) deliver around 100 hours of continuous use. Auto-shutoff preserves the battery and the protective cap keeps the electrode hydrated between measurements.

💡 BloomLED tip: in hydroponics, check pH daily and EC every time you add nutrients. A 0.5 pH drift can lock out several essential elements. The MW804 gives you the precision to intervene at the right moment.

Frequently asked questions

How often should I calibrate the Milwaukee MW804?

For daily use, a weekly calibration is enough in standard cultivation. For intensive production or heavily loaded solutions, recalibrate every 2 to 3 days. Always recalibrate after replacing the batteries or after the meter has been unused for several weeks.

Can the meter stay submerged permanently in the reservoir?

No. The MW804 is a spot-measurement instrument designed for quick readings. For continuous monitoring, choose a dedicated reservoir probe. After each measurement, rinse the probe with deionised water and store the tip in the supplied storage solution or a small amount of KCl.

What target values should I aim for in indoor hydroponics?

In vegetative growth, target a pH between 5.8 and 6.2 and an EC of 1.2 to 1.8 mS/cm. In flowering, pH stays similar (5.8-6.3) while EC can climb from 1.8 to 2.4 mS/cm depending on strain and stage. The MW804 delivers these readings with the precision needed to fine-tune your nutrient mix.

How does it differ from a simple pH tester?

A basic pH tester only measures one parameter. The MW804 adds EC (ionic concentration of your solution), TDS (dissolved matter in ppm) and temperature, which directly affects electrochemical readings. To run a serious indoor cultivation, these three complementary data points are essential.
