Technical Description
- Wide temperature range:
- RTC158: -30 to 155ºC
- RTC250: -45 to 155ºC
- Fully automatic calibration without computer connection
- Ideal thermal stability up to 0.005ºC
- Improved heat pipe technology with unique dual heat zone makes the temperature in the heat pipe synchronized
- Dynamic Temperature Compensation (DLC) technology allows the temperature in the heat pipe to be stable even when there are multiple sensors in the pipe (only available in models B and C)
- Color LCD screen, full information display (5 simultaneous temperature values; stable status; load compensation status; real-time clock; serial number of standard sensor; status of test sensor)
- Communicate with computer via USB port
- Smart standard sensor with “plug n play” plug designed at 90° angle for convenient plugging into heat pipe
- Switch test mode, Auto-stepping 20 steps easy to set up and use (B model only)
- Fast calibration, saving time
- The included JofraCal calibration software makes calibration and calibration certificate issuance simple and fast.
- RTD, TC, mA, V inputs (B model only)
- 24 VDC power supply for transmitter (B model only)
- Specially designed and convenient aluminum suitcase
