The JOFRA DTI-1000 digital temperature indicator is a fully traceable thermometer recommended as the reference instrument to verify the true temperature of any type of temperature calibrator, liquid bath or dry-block calibrator. The DTI-1000 can be used with optional JOFRA STS Superior Temperature Standard probes as the working temperature reference in nearly any calibration application, or it can be set up directly in custody transfer applications where high accuracy (low uncertainty) is important.
The superior performance of the DTI-1000 along with AMETEK’s long history of providing reliable, low-drift calibration instruments have made the JOFRA DTI-1000 and STS probes the working standard in many national laboratories worldwide. Accurate to +/-0.005°C (+/-0.009°F), the DTI-1000 employs state-of-the-art DC measuring techniques in combination with powerful microprocessor technology. It utilizes True Ohm Measurement that achieves accurate compensation for errors induced by thermal effects and eliminates the EMF from cables, sockets and sensors.
