Luster Leaf Luster Leaf Soil Moisture/pH Tester
Luster Leaf's Soil Moisture/pH Tester (model 1817) is a two-probe needle meter that checks either soil pH or soil moisture, chosen with a switch on the front. It works for house and greenhouse plants, containers and lawns, and comes with a pad for cleaning the probes.How to use pH: Remove the top 2" of soil and crumble the soil below to a depth of 5". Take out stones and debris, then wet the soil to a mud consistency, ideally with rain or distilled water. Lightly shine the left probe with the pad, set the switch to pH, push the probes straight down 4"-5", and read after 60 seconds. Moisture: Set the switch to Moisture and clean the right probe with the pad. Push the probes in about two-thirds of the container's depth, midway between the edge and the stem. Water only when the needle reads on or below the watering letter given for your plant in the instructions. Good to know For use in soil only. Do not use it in liquids. Small containers dry out faster than large ones, so check them more often.

Milwaukee Instruments Milwaukee MW101-SOIL PRO pH Meter
Summary The Milwaukee MW101-SOIL PRO pH meter has won fans around the world with its reliable, fast and simple operation as well as its toughness and accuracy. The Milwaukee PRO pH Meter is preferred by people testing samples in direct soil or with slurries that cause other pH meters to fail while taking direct readings in Hydroponics, Horticulture and farming applications. The Milwaukee PRO pH meter offers: Speed The MW101-SOIL delivers fast results to ±0.02 pH accuracy with two point calibration. Toughness The rugged meter is designed to take knocks. Paired with low maintenance, field grade MA920B/1 open junction, gel filled electrode, the MW101-SOIL is ideal for everyone from educators to horticulture professionals and growers. Design features Fast easy to read results with large digital LCD readout ±0.02 pH accuracy & 0.01 pH resolution Lightweight and portable Easy measurement: just place the probe in the sample, gently stir and wait for the reading to stabilize 3’ probe cables for extra flexibility Manual two-point calibration for increased accuracy Gel-filled, open junction, field grade pH electrode for low maintenance and high performance Auto shut off and low power demand for approx. 300 hours of continuous use (battery included) 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. Cleaning and Storage All pH sensors have a limited life and response time gets longer with age. Properly maintaining your pH pen tester will give you fast, accurate results for longer. So, be sure to order the Milwaukee pH Maintenance Kit code PH-Main at checkout time! This will be needed to help clean and condition the pH electrode before use! 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. Store the pH probe in storage solution MA9015. Only use tap water short-term if MA9015 is not immediately available and NEVER store in distilled Water (DI) or Reverse Osmosis (RO) 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 calibration 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 MA9016 for about 20 minutes. Calibration The pH sensing bulbs become less sensitive over time so make sure that you are calibrating reguarly to keep your PRO pH meter accurate. Also, calibrate after cleaning or a long period of storage.

Lightly shine 4"-5" of the probe with the supplied pad, avoiding the bullet-shaped tip, and wipe it clean. Push the probe straight down 4"-5" (never force it), twist it back and forth a few times, and read after 60 seconds. For a second reading, wipe the probe and test a new spot. If the first reading was pH 7 or above, reshine the probe and read after 30 seconds; if it was below 7, don't reshine and read after 60 seconds. Good to knowFor use in soil only.
