HOBO MX pH and Temperature Logger(MX2501)ManualHOBOData LoggersThe HOBO MX pH and Temperature logger is designed for long-term monitoring of pH inaquatic systems.With a replaceable pH electrode and anti-biofouling copper guard,thisdurable logger can be deployed in both fresh and salt water environments.This logger isBluetooth Low Energy-enabled for wireless communication with a mobile device.Using theHOBOmobile app,you can easily calibrate and configure the logger,download logged data toyour phone or tablet,or automatically upload the data to HOBOlink for further analysis.Youcan also configure the logger to calculate statistics,set up alarms to trip at specific thresholds,or enable burst logging in which sensor readings are logged at a faster interval when the pH orHOBO MX pH andtemperature rises a bove or falls below certain limits.Temperature LoggerSpecificationsMX2501pH Sensorin pHin mVIncluded Items:Range2.00to12.00pH-512to512mWpH electrode in storagesolutionAccuracy0.10 pH units within10'C of0.20mV.Electrode storage solutiontemperature at calibrationbottle and capResolution0.01pH0.02mVAnti-biofouling copperResponse Time1 minute typical to 90%at constant temperature in stirred waterguard.Silicone-based O-ringTemperature Sensorgrease and foam swabRange-2*t050℃(28.4°t0122F)Required Items:Accuracy0.2℃(0.36F).HOBOmobile appResolution0.04℃(0.072℉)】·Device with iOS andBluetoothResponse Time7 minutes typical to 90%in stirred water.Deionized or distilled waterand squirt bottleLogger.Calibration solutionsOperating Range-2*to 50"C (28.4*to 122*F)-non-freezingAccessories:BuoyancyFresh water:13.6 g(0.48 oz)negativeSalt water:19.6 g(0.69 oz)negativeReplacement pHelectrode(MX2500-ELECTRODE)WaterproofTo40m(131.2ft)Calibration kit with threeWater DetectionWater conductivity level of 100 uS/cm or greater is necessary forbottles:pH 4.01,7.00,andreliable detection of water.Deionized water or water below 100 uS/cm10.00 calibration solutionmay not be detected.(MX2500-CAL-KT)）andThe water conductivity circuit may not reliably detect water that hascalibration beakerfrozen around the electrodes,i.e.below 0'C (32"F).(MX2500-CAL-BKR)Maintenance kit withRadio Power1 mW (0 dBm)calibration kit plus storageTransmission RangeApproximately 30.5 m(100 ft)line-of-sight in airsolution(MX2500-MAINT-k灯T)Wireless Data StandardBluetooth Low Energy(Bluetooth Smart).pH4.01 calibration solutionLogging Rate1 second to 18 hours(MX2500-CAL-4.pH 7.00 calibration solutionLogging ModesFixed interval (normal,statistics)or burst(MX2500-CAL-7)Memory ModesWrap when full or stop when full·pH10.00 calibrationStart ModesImmediate,push button,date time,or next intervalsolution (MX2500-CAL-10).Electrode storage solutionStop ModesWhen memory is full,push button,date time,or after a set logging(MX2500-STORE-SOLN)periodReplacement sensor endTime Accuracy#1minute per month O'to 50'C(32*to 122F)cap (MX2500-END-CAP)·Replacement anti-Battery TypeOne AA 1.5 Volt,user-replaceablebiofouling copper guardBatte
