Just set your pH parameters and let the Milwaukee pH Controller and pump do the rest.The Milwaukee PRO pH controller kit is preferred by people looking to dial in their testing program when they have an ongoing need to maintain levels. Common uses are nutrient tanks and aquariums.The Milwaukee PRO pH controller and pump offers:\u003cbr\u003eACCURACY\u003cbr\u003eThe Milwaukee PRO pH controller offers an accuracy to¬†¬±0.2 pH with two point manual calibration.\u003cbr\u003eAUTOMATION\u003cbr\u003eThe controller provides a control range of 5.5 to 9.5 pH with alarms that activate when readings are higher or lower than set point.\u003cbr\u003eCOMPATIBLE DOSING PUMP\u003cbr\u003eThe Milwaukee MP810 dosing pump (designed specifically for use with the MC122) is included in the kit.\u003cbr\u003eEASY INSTALLATION\u003cbr\u003eThe MC720 pH controller and pump kit comes with a complete mounting kit including a probe holder.\u003cbr\u003eDESIGN FEATURES\u003c\/p\u003e\u003cp\u003eFast easy to read current results with large digital LCD readout\u003cbr\u003e  Accurate to ¬±0.2 pH (0.0 pH to 14.0 pH) with the user selectable high\/low set points\u003cbr\u003e  Simple two-point calibration for increased accuracy with manual trimmers for easy adjustment\u003cbr\u003e  Gel-filled, double junction lab grade pH electrode for low maintenance and high performance\u003cbr\u003e  6.5 feet probe cables for extra flexibility when testing\u003cbr\u003e  12 VDC power supply\u003cbr\u003e  Pump provides a maximum pressure of 1.5 bar or more than 50 feet of head pressure with a 0.16 GPM dosing flow.\u003c\/p\u003e\u003cp\u003eUSE AND CARE¬†\u003cbr\u003epH 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.\u003cbr\u003eSENSING BULB\u003cbr\u003eThe glass bulb loses sensitivity with use and will eventually fail. This is true of all pH probes.\u003cbr\u003eREFERENCE JUNCTION\u003cbr\u003eThe 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.\u003cbr\u003eSTORAGE\u003cbr\u003eThe 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.\u003cbr\u003eCLEANING\u003cbr\u003eResidue 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.\u003cbr\u003eCALIBRATION\u003cbr\u003eThe 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.\u003cbr\u003eMC122 SPECIFICATIONS\u003c\/p\u003e\u003cp\u003eRange: 0.0 - 14.0 pH\u003cbr\u003e  Resolution: 0.1 pH\u003cbr\u003e  Accuracy: ¬±0.2 pH\u003cbr\u003e  Set point: 5.5 to 9.5 pH\u003cbr\u003e  Calibration: Manual 2 points\u003cbr\u003e  Alarm Active when reading is higher or lower than set point\u003cbr\u003e  Dosing Contact: 1 power plug for CO2 dosing\u003cbr\u003e  pH electrode: MA911B\/2 (included)\u003cbr\u003e  Environment: 0 to 50¬∞C \/ 32 to 122¬∞F; max RH 95%\u003cbr\u003e  Power Supply: 12 VDC adapter (included)\u003cbr\u003e  Power Drivers: 115 VAC, 2A, 60Hz or 230 VAC, 1A, 50Hz\u003cbr\u003e  Mounting kit (Included)\u003cbr\u003e  Dimensions: 5.9 x 3.2 x 1.35 inches\u003cbr\u003e  Weight: 6.3 ounces (meter only)\u003c\/p\u003e\u003cp\u003eMP810 SPECIFICATIONS\u003c\/p\u003e\u003cp\u003eMax.
