MILWAUKEE INSTRUMENT pH 600 | pH Tester

Compact digital tester for measuring the pH of irrigation water and nutrient solutions. Designed for quick checks in the tank and in the growroom.

Key features

1. Parameter measured: pH
2. Range: 0,0 – 14,0 pH
3. Resolution: 0,1 pH
4. Accuracy: ±0,1 pH (at 25 °C)
5. Battery life: up to 700 hours of use

Overview

What it is for

It is used to check the acidity of the nutrient solution or irrigation water. A pH outside the target range can reduce nutrient availability and make crop management less stable.

Who it is for

1. Indoor and outdoor growers who want simple, portable pH control
2. Users in soil, coco, or hydroponics who measure directly on a sample
3. Those who prefer a “pen” format with immediate display reading

What makes it different

1. Manual calibration via calibration screw
2. Operating conditions declared for practical use: 5–50 °C and up to 95% RH
3. Power supply from 3 × 1,5 V alkaline batteries with long operating life

How to use

Measurement

1. Remove the protective cap.
2. Switch on the instrument.
3. Immerse the sensor tip in the sample, avoiding impacts against the sides and bottom.
4. Wait for stabilization and read the value on the display.
5. Rinse the tip after use.

Calibration

1. Use a pH 7,01 buffer solution.
2. Pour a small amount of buffer into a clean container.
3. Immerse the electrode in the buffer.
4. Adjust the calibration screw until the reading is pH 7,0.

Maintenance

1. Rinse the electrode after each measurement.
2. Store the electrode with a few drops of electrode storage solution in the cap.

Warnings

1. Do not store the electrode in distilled or deionized water.
2. Do not use outside the operating conditions indicated by the manufacturer.

FAQ & growing tips

How often is it advisable to recalibrate?

It depends on frequency of use and working conditions. A good practice is to check calibration regularly and recalibrate when the reading becomes unstable or after periods of inactivity.

Can I measure directly in the tank?

It is possible, but it is often safer to take a sample in a clean glass to reduce the risk of impacts to the sensor.

Why can the value fluctuate?

Common causes include a dirty electrode, incorrect maintenance, or outdated calibration. Rinse, clean according to the manufacturer's instructions, and recalibrate with buffer solution.
