Range: 0 to 50000 lux RESOLUTION: ±1, ±10, ±100 MW700 is a portable lux meter designed to measure light in the 0 to 50000 lux range. This convenient, ergonomic lux meter is ideal for anyone seeking fast, reliable light measurements. The instrument is suitable for a wide range of applications, including hydroponics, agriculture, horticulture and environmental analysis. The light sensor is attached to a 1.3 m (4.4') cable and is suitable for checking light intensity. Average indoor lighting ranges from 100 to 1000 lux, while average outdoor sunlight is around 50000 lux. Design features Fast, easy-to-read results on a large digital LCD display Silicon photodiode sensor attached to a 4.4' cable Three resolution settings – 1, 10 and 100 Battery life of 150 hours of continuous use (battery included) with a low-battery warning.

Milwaukee EC45 PRO is a professional instrument for rapid measurement of electrical conductivity (EC), total dissolved solids (TDS) and Conductivity Factor (CF) in nutrient solutions. Designed specifically for hydroponics, greenhouses, fertigation systems and professional horticulture, it provides instant measurements without calibration. Its IP67 waterproof housing floats on water and is suitable for daily use in reservoirs and mixing tanks.

Milwaukee EC45 PRO is designed for growers who want to monitor nutrient-solution concentration quickly and reliably. Maintaining the correct EC value is essential for optimal nutrient uptake and preventing plant deficiency or overfeeding. EC45 PRO measures EC, TDS (500 and 700 ppm scale) and CF, allowing use of the grower's preferred measurement system.

The instrument is exceptionally easy to use – simply immerse the measuring section in the solution. It has no buttons, switches on automatically when immersed and, once the reading stabilises, switches itself off after about 30 seconds, greatly extending battery life. The bright 24-LED indicator shows the measured value, battery status and warnings for values outside the measurement range.

Unlike standard EC testers, EC45 PRO is factory calibrated and does not require periodic user calibration. The graphite electrodes resist build-up, and the robust housing allows the instrument to be used as a stirring rod when preparing nutrient solutions. Thanks to automatic temperature compensation, readings remain accurate between 5°C and 50°C.

You can extend the life of your pH electrode as follows:

1. Storage: The pH probe must be kept hydrated. Long periods of dry storage will harm the probe's sensitivity. Allowing the probe to dry may also cause deposits and clogging at its tip. Storing it in MA9015 storage solution or pH calibration buffers will help address both issues. Do not store in tap water or distilled water! This will damage the probe's sensitivity. The best way to store the probe is with the probe cap filled with storage solution or calibration buffer and the cap tightened to prevent leakage. It is also recommended that the electrode be stored upright to further reduce the potential for leakage.
2. Cleaning: Deposits on the probe tip from the mineral salts of the nutrient solution or from organic material can affect its sensitivity and clog it. We recommend regularly soaking your electrode in MA9016 cleaning solution.
3. Calibration: the glass tip of the pH probe becomes less sensitive over time, so make sure to calibrate regularly to keep your meter accurate. Also calibrate after cleaning or a long period of storage.
