The pHTemp2000 is a battery powered, stand alone pH and temperature logger with an LCD. This all-in-one compact, portable, easy to use device will measure and record up to 131,071 readings per channel. The pHTemp2000 will directly connect to many commonly used pH, ORP and ISE 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.

**Temperature specifications based on ideal 100 ? Pt RTD compliant with IEC 751 (1983) and ITS-90, 5000 ? FSR (accuracy ased on 36” lead wire RTD with 4 wire configuration)
***Calibrated accuracies based on standard MadgeTech calibrations for 0 ? to 200 ? range.
****100 ?, 2 or 4 wire RTD probes are recommended for the most accurate performance. Most 100 ?, 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 ?. (Note: Please contact the manufacturer of the RTD probe for questions on the resistance)
For use in harsh environments, this device must be well protected from weather, steam and harsh chemicals
