Ametek Jofra DTI-1000 Temperature Indicator, -200 to 750 °C, NPL Traceable (DTI1000AF)
Ametek Jofra DTI-1000 Temperature Indicator, -200 to 750 °C, NPL Traceable (DTI1000AF)
Overview
The Jofra DTI-1000 is the working standard in many national laboratories and is recommended for verifying the true temperature of any temperature calibrator, liquid bath or dry-block calibrator. The Model A input handles Pt100 or Pt25 reference sensors over two channels with a differential measurement option, and True Ohm Measurement, a 4-wire technique, eliminates the electromotive force errors caused by cables, sockets and sensors.
With user-selectable resolution of 0.1, 0.01 or 0.001 °C, °F, K or Ω, the indicator maintains ±0.004 °C one-year accuracy and ±0.03 °C system accuracy when used with STS Series sensors. The two-line VFD display, RS-232 interface, mains or 8 x 1.5 V AA battery power, and the included JofraCal software and NPL-traceable certificate (F option) make it a fully traceable reference for custody transfer and calibration work.
