AG900 Standard Portable pH / Conductivity / TDS Combination Meter Kit by Milwaukee

3 meters in 1! This meter allows you to measure pH, EC (conductivity) and TDS with just one instrument and one single probe!

The AG900, with a conductivity range that goes up to 6.00 mS/cm and the TDS up to 4000 ppm is ideal for testing in crop production. Soil and well water pH that is too acidic or alkaline can have an adverse effect on plant nutrient and water uptake and directly effect the efficiency of fertilizer, herbicides and pesticides. Soil Conductivity is checked before fertilizer application to pinpoint field needs and after fertilization to establish its effectiveness.

Supplied with the SE600 interchangeable probe to measure pH, Conductivity and TDS. The pH electrode utilizes a fiber junction to reduce contamination when measuring fertilizer solutions. Both meters calibrate manually in pH, Conductivity and TDS.

Includes

• MW802 ( ph/ec/tds ) Combination Meter
• Carrying Case
• pH 230ml Bottle 7.01 Calibration Solution

USE AND CARE

pH meters usually start performing poorly because of problems with the probe. The two parts of the pH probe that cause problems are the glass sensing bulb and the reference junction.

SENSING BULB

The glass bulb loses sensitivity with use and will eventually fail. This is true of all pH probes.

REFERENCE JUNCTION

The reference junction is a small hole that allows the meter to compare the sample to a reference. The reading is generated based on the electrical difference between the sample and reference. If the junction hole gets clogged, the pH probe will no longer function.

You can extend the life of your pH electrode in the following ways.

STORAGE

The pH probe needs to be kept hydrated. Long periods of dry storage will damage the sensitivity of the probe. Allowing the probe to dry out may also result in the junction hole getting clogged.

Storing in pH probe storage solution or pH calibration buffers will help address both these issues. Do not store in tap water and DI water. This will damage the sensitivity of the probe.

The best way to store the probe is with the probe's cap filled with storage solution or calibiration buffer and the cap tightened to prevent leakage. It is also recommended that to store the electrode upright to further reduce the potential for leakage.

CLEANING

Residue from the sample can impact the sensitivity of the sensing bulb and clog the junction. This is especially true if the sample has a lot of organic material. We recommend regularly soaking your electrode in cleaning solution.

CALIBRATION

The pH sensing bulbs become less sensitive over time so make sure that you are calibrating reguarly to keep your PRO pH controller accurate. Also, calibrate after cleaning or a long period of storage.
