pH Monitoring

Laboratory Product > Water Quality
The pHTemp2000 is a battery powered, stand alone pH and temperature data  logger with an LCD.
This all-in-one compact, portable, easy to use  device will measure and record data up to 131,071 readings per channel.
The pHTemp2000 will directly connect to many commonly used pH and ORP  electrodes through a female BNC connector mounted on its side.
Temperature is measured by directly connecting an RTD to the pHTemp2000.  Temperature compensation is automatically done internally to the unit.
The  storage  medium  is  non-volatile  solid  state  memory,  providing  maximum  data  security even if the battery becomes discharged. The device can be started and stopped directly from your computer.
The pHTemp2000 makes data retrieval quick and easy. Simply plug it into an empty USB port and our user-friendly software does the rest.

Applications :
  • Surface and ground water quality monitoring
  • Environmental and wetlands monitoring
  • Industrial influent and effluent
  • Water districts and municipal water systems
  • Process water quality
  • Recreation and park management
  • Pulp and paper industry
  • Wastewater monitoring

pH Accuracy: ±0.01 pH
pH EMI Susceptibility: <0.2 pH@3 V/M, 80 MHz to 1 GHz
ORP/ISE Accuracy: ±0.1 mV
ORP/ISE EMI Susceptibility: <10 mV@3 V/M, 80 MHz to 1 GHz

**Temperature specifications based on ideal 100 Ω Pt RTD compliant with IEC 751 (1983) and ITS-90, 5000 Ω FSR (accuracy based on 36” lead wire RTD with 4 wire configuration)
***Calibrated accuracies based on standard MadgeTech calibrations for 0 Ω to 200 Ω range.
****100 Ω , 2 or 4 wire RTD probes are recommended for the most accurate performance. Most 100 Ω , 3 wire RTD probes will work, but MadgeTech cannot guarantee the accuracy. To determine whether or not the 3-wire RTD probe will work, the resistance between the two same colored wires should be less than 1 Ω.
For use in harsh environments, this device must be well protected from weather, steam and harsh chemicals

pH Rugged Electrode
A submersible CPVC pH Electrode  that is suited for use in outdoor applications such as monitoring drums,  tanks or streams. To interface with a MadgeTech pH data logger, a cable assembly is required and must be purchased separately.

The pH-Rugged Electrode is a submersible CPVC pH electrode that is  suited for use in outdoor applications such as monitoring drums, tanks  or streams. The electrode has a quick latch mechanism which allows it to  be inserted into a BNC connector by simply rotating it a quarter turn.  For use with the MadgeTech pH loggers, a cable assembly and an RTD  temperature reference is required.

Two mounting assembly options are available. The pH-Rugged ATC Cable mounting assembly connects directly to the pH-Rugged Electrode and has a built in RTD probe, providing automatic temperature compensation (ATC). The pH-Rugged Probe cable assembly connects to the pH-Rugged Electrode and can be used with an external RTD probe or may be used with one of the resistor kits included with the MadgeTech pH loggers. Automatic Temperature Compensation is preferred, as it provides the best accuracy. When the precision and accuracy of ATC is not necessary, use the included resistor kit to simulate the temperature of the application to minimize error.

Compatible with the MadgeTech pHTemp2000 data logger.
Resistor Kit: Reference the table included with the resistor kit to calibrate the resistor to simulate the temperature of the application.
Life expectancy: The pH-Rugged Electrode has a life expectancy of 6-12 months depending on use.
