Product Description Biobase PH MeterProduct DescriptionFeatures:* Stability indicator automatically shows current measurement status.* Auto-Hold function freezes stable reading for easy viewing and recording.* Automatic electrode diagnosis shows offset and electrode slope.* Reset feature automatically resumes parameters back to factory default options.* Help message as a operational guide that helps you quickly using the meter(for PH-220).* Manual temperature calibration improves the measurement accuracy of meter(for PH-320).* Selectable temperature unit (°C or°F ) meets different application requirements(for PH-320). pH Mode (For PH-221/320):* 1 to 5 points push-button calibration with auto-buffer recognition.* Automatic electrode slope display helps user decide whether to replace sensor.* Automatic Temperature Compensation provides accurate measured values.* Calibration Due Reminder prompts you to calibrate the meter regularly. ORP Mode(For PH-221/320):* 1 point offset calibration allows adjusting the displayed value to a known standard.* Relative and absolute mV measurement modes provide accurate ORP readings. Ion Concentration Mode(For PH-320):* 2 to 5 points calibration providing the 8 concentration points can be selected.* Automatically recognize ion electrodes, does not need to specify the type of ion.* Direct ion concentration readout simplifies the elaborate measurement process.* Selectable multiple concentration units include the ppm, mg/L and mol/L.Detailed Photos Product ParametersModelPH-220PH-221pHpH Range-2.00-20.00pH-2.000~20.000pHpH Accuracy±0.01 pH±0.002pHResolution0.01 pH0.1, 0.01, 0.001 pH, SelectableCalibration Points1 to 3 points1 to 5 pointspH Buffer OptionsUSA (4.01/7.00/10.01),NIST (4.01/6.86/9.18)USA (pH1.68/4.01/7.00/10.01/12.45),NIST (pH1.68/4.01/6.86/9.18/12.45),DIN (pH1.09/4.65/6.79/9.23/12.75)or 2 custom buffersORPmV Range-1999-1999mV-1999.9-1999.9mVmV Accuracy±1mV±0.2mVResolution1mV0.1,1mV, SelectableCalibration Points/1 pointTemperatureTemperature Range0~105°C/32221°FTemperature Accuracy±0.5°C/±0.9°FResolution0.1°C/0.1°FOffset Calibration1 point, reading ±10°COtherSpecificationsTemperature Compensation.100°C, manual or automaticStability Criteria/Low or highCalibration Due Alarm/1 to 31 days or offSlope/Offset DisplayYesHold FunctionManual or auto-endpointAuto-Off30 minutes after last key pressed10, 20 or 30 minutes afterlast key pressedMemory100 data sets500 data setsCommunication InterfaceUSBConnectorBNC, 3.5 mm jack socketDisplayCustom LCD (80 x 60 mm)Power Requirements3*1.5V AA batteries or DC5V power adapterBattery LifeApproximately 150 hours (Turn off the backlight)Dimensions(W*D*H)170*85*30mmPackage Size(W*D*H)475*155*350mmNet Weight300gGross weight2kgPackaging & ShippingCompany ProfileOne-stop PurchaseContact us
