Ametek DTI-1000 [DTI1000BF] Digital Temperature Indicator, -200 to 750°C; Pt25 Only w/Traceable Certificate to International Standards. The Ametek DTI-1000 digital temperature indicator is a fully traceable thermometer recommended as the reference instrument to verify the true temperature in any type of temperature calibrator, liquid bath, or dry-block calibrator. Use the Ametek DTI-1000 digital temperature indicator as your working temperature reference in any calibration application or in custody transfer applications where high accuracy is imperative. The Ametek DTI-1000 digital temperature indicator combines superior specifications with a long history of reliability and low drift making it the working standard in many national laboratories worldwide. The Ametek DTI-1000 digital temperature indicator uses Ametek STS industrial temperature reference probes which are available separately. STS probes are rugged and economical and offer fast response times, low immersion depths, compact physical sizes, and specified low drift rates even at high temperatures. The Ametek DTI-1000 digital temperature indicator features dual channel input capable of differential measurement. An easy-to-read VFD display and dedicated function keys make set-up and operating the Ametek DTI-1000 digital temperature indicator simple. Reliable temperature measurements from -328 to 1382°F are accurate up to ±0.009°F with help from the 4-wire true ohm measuring principle which eliminates electromagnetic interference from cables, sockets, and sensors. The Ametek DTI-1000 digital temperature indicator also features an RS232 serial data communication interface which allows the instrument to be serially connected to a personal computer for data storage and reporting. The JOFRACAL software package is included as a standard accessory.
