Altek 211 RTD Calibrator lets you simulate and read RTDs over the entire industrial temperature range. Use with transmitters, single & dual channel recorders, controllers, alarms and indicators. Switch between four Pt 100, one Pt 1000, one Cu 10, two Ni RTD curves or ohms ranges from 0.00 to 410.00 and 0.0 to 2010.0.Altek 211 display gives you fast, accurate temperature measurement with 0.1 and 1 degree or with 0.01 and 0.1 ohm resolution. Two, three and four wire hookups assure accuracy in short or long cable runs. Open RTDs and leads are detected and indicated on the LCD display. Two readings per second track fast moving temperatures.
