Different scales include the 500 scale, 650 scale and the 700 scale. However, true PPM can only be determined through chemical analysis.Your mS\/cm reading can be approximately converted to TDS (ppm) as shown in the examples below.2.00 mS\/cm = 2000 uS\/cm = 1000 ppm on .50 factor scale2.00 mS\/cm = 2000 uS\/cm = 1400 ppm on the 442 scale or .70 factor scale\u003cbr\u003eSPECIFICATIONS\u003cbr\u003eEC Range: 0.00-20.00 mS\/cm\u003cbr\u003eTDS Range: 0.00-10.00 ppt\u003cbr\u003eTemp Range: 0.0 to 60.0¬∞C \/ 32.0 to 140.0¬∞F\u003cbr\u003eEC Resolution: 0.01 mS\/cm\u003cbr\u003eTDS Resolution: 0.01 ppt\u003cbr\u003eTemp Resolution: 0.1¬∞C \/ 0.1¬∞F\u003cbr\u003eEC Accuracy: 2% Full Scale\u003cbr\u003eTDS Accuracy: 2% Full Scale\u003cbr\u003eTemp Accuracy: ¬±0.5¬∞C \/ ¬±1¬∞F\u003cbr\u003eEC Typical EMC Deviation: 2% Full Scale\u003cbr\u003eTDS Typical EMC Deviation: 2% Full Scale Temp\u003cbr\u003eTypical EMC Deviation Temperature: ¬±0.5¬∞C \/ ¬±1¬∞F\u003cbr\u003eCalibration: Automatic, 1 point\u003cbr\u003eTemperature Compensation: Automatic, with Œ≤=0.0 to 2.4%\/¬∞C\u003cbr\u003eProbe: Mi59P (replaceable)\u003cbr\u003eEnvironment: 0 to 50¬∞C \/ 32 to 122¬∞F; max RH 100%\u003cbr\u003eBattery Type: 4 x 1.5V; IEC LR44, A76 (included)\u003cbr\u003eBattery Life: Approx. 100 hours of use\u003cbr\u003eAuto-off: After 8 minutes of non-use\u003cbr\u003eDimensions: 7.9 √ó dia 1.5 inches\u003cbr\u003eWeight: 3.5 ounces\u003c\/p\u003e","brand":"Milwaukee Instruments","offers":[{"title":"Default Title","offer_id":58455880270127,"sku":"107642","price":60.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0978\/4875\/4479\/files\/7ac89164107642.jpg?v=1789191980"},{"product_id":"milwaukee-mc110-pro-ph-monitor-mid-range","title":"Milwaukee MC110 PRO pH Monitor Mid Range","description":"\u003cp\u003eThe Milwaukee MC110 PRO Mid Range pH monitor offer lab grade accuracy with an easily viewable continuous check on pH levels with alarms.\u003cbr\u003eDESIGN FEATURES\u003cbr\u003eFast easy to read results with large digital LCD readout.\u003cbr\u003eAccuracy to ¬± 0.2 pH with a full 0 pH to 14 pH range.\u003cbr\u003eSet point range of 3.5 to 7.5 pH with visual alarm activated when reading is higher or lower than set point.\u003cbr\u003eComes with full mounting kit including probe holders.\u003cbr\u003eLab grade probe included with a double junction, gel filled design for low maintenance.¬†\u003cbr\u003eStarter Calibration 1 x 20 mL solution M10007B (7.01 pH).\u003cbr\u003eMILWAUKEE PRO PH PROBE CARE¬†\u003cbr\u003epH meters usually start performing poorly because of problems with the probe.

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 pen 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.This 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.\u003cbr\u003eCLEANING\u003cbr\u003eResidue from the sample can impact the sensitivity of the sensing bulb and block the junction.
