RTC Series

Ametek Jofra's most advanced and accurate portable temperature calibrator with the widest available temperature range. One of its great features is the patented DLC system for perfect temperature uniformity in the insert – even when calibrating large sensors or many sensors at a time.

The RTC Series also feature active dual- and triple-zone temperature control which provides excellent temperature homogeneity in the well.

• Temperature range from -100 to 700°C (-148 to 1292°F) with 7 models
• Accuracy to ± 0.04°C and Stability to ± 0.005°C
• Dry block and liquid bath / dry block combined
• Time-saving fast cooling and heating times
• Contamination free calibration of clamp sensors
• “Plug and Play” intelligent reference sensors
• Easy-to-read colour display with User-friendly navigation
• Lightweight and easy to carry
• Multi-hole insert kits
• JofraCal Calibration Software

Improved temperature homogeneity
The unique active dual-zone block ensures good temperature homogeneity in the calibration zone safely.

DLC - Dynamic compensation of load (PATENT PENDING)*

Perfect temperature homogeneity in the sleeve, even when the calibration of large sensors or more sensors at the same time.

* Only present on the B and C models.

In the display for the temperature homogeneity*

Shows the temperature in °C in the homogeneity of the sleeve when the DLC technology is used.

* Only present on the B and C models.

Intelligent reference sensors

JOFRA reference sensors are supplied with intelligent plugs, which are located in the calibration data (coefficients). This is a true "plug and play" system. The data of Reference Sensors must not be entered manually.

USB communication

All RTC calibrators have a USB interface.

Time-saving

Very fast cooling and heating times.
