HM DIGITAL TDS-EZ PPM METER

 Economy model that is ideal for end-users.

• Highly efficient and accurate due to its advanced microprocessor technology.
• Hold Function: saves measurements for convenient reading and recording.
• Measurement Range: 0-9990 ppm. From 0-999 ppm, the resolution is in increments of 1ppm. From 1000 to 9990 ppm, the resolution is in increments of 10ppm, indicated by a blinking 'x10' image.
• Factory Calibrated: HM Digital meters are calibrated with a 342 ppm NaCl solution. Meters can be recalibrated with a mini-screwdriver.
• Includes a TDS chart sticker on the back of the meter that explains TDS values.

 MILWAKEE PH TESTER PH600

Milwaukee's most affordable pH tester, range: 0.0 to 14.0 pH, with one point manual calibration and accuracy of_+ 0.2 pH. Battery Life: 700 hours. Calibration solution sold separately. 30 day warranty.

HANNA COMBO TESTER W/ LOW RANGE EC

The HI 98129 Combo waterproof tester offer high accuracy pH, EC/TDS and temperature measurements in a single tester! No more switching between meters for your routine measurements. The waterproof Combo (it even floats) has a large easy-to-read, dual-level LCD and automatic shut-off. pH and EC/TDS readings are automatically compensated for the effects of temperature (ATC). This technologically advanced tester has a replaceable pH electrode cartridge with an extendable cloth junction as well as an EC/TDS graphite electrode that resists contamination by salts and other substances. This gives these meters a greatly extended life. Your tester no longer needs to be thrown away when the pH sensor is exhausted.

The EC/TDS conversion factor is user selectable as is the temperature compensation coefficient (ß). Fast, efficient, accurate and portable, the Combo pH, EC/TDS and temperature tester brings you all the features you've asked for and more!

OAKTON ECO TESTR PH2

• Automatic temperature compensation.
• Waterproof, dust proof housing that floats.
• Easy to use; push-button calibration with auto buffer recognition.
• Includes transparent electrode cover/sample cup.
• Range: 0.0 to 14.0 pH.
• Low-cost pocket sized meter.
• Push-button calibration, HOLD function, and error messages.
• Power: four 1.5 Volt button cell batteries (included).

EC/PH/TEMP CONTINUOUS MONITOR

This meter gives you the ability to monitor pH level, Nutrient Levels in EC and Nutrient Temperature.

This continuous monitoring system requires no batteries, just plug it in to an AC wall receptacle and the meter will remain in a calibration mode for months. The Nutradip® Tri-Meter, with automatic temperature compensation, is the best way of measuring the strength of nutrients in your water, pH, and monitoring temperature at the same time. 2 year limited warranty on meter. 6 months limited warranty on the probe.

HANNA CALIBRATION SOLUTIONS



TDS solution are produced with high-quality potassium chloride in various concentrations. They are standardized using a conductivity meter calibrated with NIST potassium chloride.

The 1413 μS/cm solution is the one best suited for general use. This solution is also available in combination kits with the pH 7 buffer for the easy calibration of multiparameter instruments.

BOND SOIL MOISTURE METER

Measures moisture content of soil. Lets you know when to water. No batteries needed. For indoor or outdoor use.

RAPITEST 4 WAY SOIL ANALYZER

Measures four different levels for fertilizer, light, moisture and pH. Includes instructions and guides for all four measuring levels.

• Instantly tells you the fertility of your soil.
• Instantly tells you how acid or alkaline your soil is by measuring the pH level.
• Instantly tells you when to water your plants by measuring the moisture level.
• Measures the light intensity in foot candles.

CWP EC CALIBRATION SOLUTION

Control Wizard Products 1382 Conductivity Standard. Use to calibrate all meters that use the 1 EC to 500 ppm water standard.

GENESIS CALIBRATION SOLUTIONS

These solutions are used to calibrate pH meters to assure they are accurate and working properly. You should check your pH meter frequently because the properties of the meters membrane is constantly changing from normal use and aging. We recommend a two point calibration between 4.0 and 7.0 to assure that your meter is accurate across the scale. This is why the Genesis solution is available in twin packs of 4.0 and 7.0.

EARTH JUICE PH ADJUSTING CRYSTALS

An enlightened concept in pH control, a crystallized pH adjuster for the professional & hobbyist. For soil, soilless, hydroponic, hydro-organic and foliar applications. For use with organic and synthetic fertilizers, herbicides and pesticides.

GENERAL HYDROPONICS PH ADJUSTING SOLUTIONS

PH UP:

This Base solution is formulated using Potassium Hydroxide and Potassium Carbonate. Add a little at a time when your nutrient pH is too low in order to raise the pH to the proper level.

This powder based formula is made to raise the pH in a reservoir. Lightweight in comparison to liquids.



PH DOWN:

The Acid formulation uses food grade Phosphoric acid to lower the pH to the proper level.

This powdered acid formula is easy to handle and ship. Lightweight in comparison to liquids. Widely recognized as a consistent and reliable product.
