EC40 EC Nutrient Stick by Milwaukee

The Milwaukee EC/TDS Nutrient Meter is designed for Hydroponics, horticulture and agriculture to help you make sure that your vegetables and plants are receiving the right amount of nutrient to promote healthy growth with low to zero product waste. Keep EC/TDS in your target range to help your achieve better results.

DESIGN FEATURES

• Measures conductivity (EC) and total dissolved solids (TDS) with automatic temperature compensation.
• Ideal range for Hydroponics (0.2 to 4 mS/cm | 2 to 40 CF | 140 to 2800 ppm 0.7 scale | 100 to 2000 ppm 0.5 scale).
• Units directly in mS/cm/CF/PPM (no conversions required).
• Factory calibrated no continious calibration required.
• High accuracy.
• Automatic Temperature Compensation (ATC).
• Auto on/off feature.
• Blue LED display.
• Graphite electrode in ABC + PC body.
• Battery level indicators.
• Battery life up to 3 years with approx. 10 measurements per day.
• 3 X 1.5V AA (batteries included).

MAINTENANCE

EC/TDS electrodes can develop nutrient build up over time. To miminize build up, always rinse the probe in fresh tap or DI water after every use.

CONVERTING EC TO TDS

The Milwaukee EC40 meter, like all conductivity meters, provides a measure of electrically charged ions in a solution and is an absolute measure of conductivity.

EC is often converted to TDS in parts per million (ppm). Different scales include the 500 scale, 650 scale and the 700 scale. However, the EC40 has all the readings direct EC/TDS/CF.

Your μS/cm reading can be approximately converted to TDS (ppm) as shown in the examples below.

1 μS/cm = 0.5 ppm on a .5 factor scale

1 μS/cm = 0.7 ppm on a .70 factor scale (442)

MGridSet Measurement Grid with Holder by Zarbeco

This Metric Grid has a 10 x 10 Matrix of .7mm x .7mm Squares. One square is further divided into a 10 x 10 Matrix of .07mm Squares. The Grid Line Widths are .001"± .0001" (.025mm±.0025mm).

The Pattern can be in direct contact with the object to be measured. The MGrid can be used to calibrate your MiScope or digital microscope. The holder can be used to raise your MiScope to be even with the MGrid when calibration of a flat object (like paper).

The Reticle Pattern is very durable, double layer, deposited evaporative Chrome/Chrome Oxide, for a reflectivity of less than 5% looking at the pattern. The Patterns on all Reticles manufactured are replicated from Precision Chrome on Glass Tooling under clean room conditions.

Features

• Accurate reference pattern for precise calibration
