The Ametek Jofra RTC-700 is an industry-leading, high accuracy, dry block reference temperature calibrator engineered for absolute control, stability and fast performance from 33 to 700°C.

Advanced features including active triple-zone heating technology and a dynamic load compensation (DLC) sensor system ensure reliable and precise temperature calibrations.

Key Features & Specifications

Wide Temperature Range:
Operates between 33 and 700°C

Fast Heating, Cooling and Stabilisation Times:
Heats from 33 to 700°C in 45 minutes
Cools from 700 to 100°C in 43 minutes
Cools from 100 to 50°C in 17 minutes
Cools from 50 to 33°C in 20 minutes
Reaches stability in 10 minutes

Superior Accuracy, Stability and Resolution:
Accurate to 0.11°C with external reference sensor
Accurate to 0.29°C with internal reference sensor
Stability of 0.008°C
Adjustable resolution of 1 / 0.1 / 0.01 / 0.001°C / °F / K

Active Triple-Zone Heating Control:
Three independently controlled zones maintain consistent dissipation and compensate for heat loss in the upper zone to ensure temperature uniformity throughout the well.

Dynamic Load Compensation:
A dynamic load compensation (DLC) sensor system provides thermal stability in the insert and compensates for the effects of mass loading to preserve accuracy when testing multiple or large sensors.

Extended Immersion Depth & Insert Width:
A deep 200mm (7.87)" well supports diameters up to 16mm (5/8") for calibration of long, wide probes and sensors.

Smart Sensor Plug & Play Connectivity:
Intelligent reference sensors store individual calibration data for efficient, convenient and error-free operation.

Mains Variance Immunity:
Mains variance immunity (MVI) maintains stability and accuracy during power fluctuations caused by large electrical motors or heavy industrial equipment.
MVI circuitry continuously monitors the RTC-700's supply voltage, making adjustments to ensure a consistent energy flow to the heating elements.

Time-Saving Automation and User-Friendly Features:
Auto-stepping and switch test functions automate routine procedures, saving time and streamlining operations.
An internal memory saves data for multiple calibration set-ups.
The menu system is intuitive, logical and easy to navigate.
A full colour 5.7" VGA display is clear, bright and easy to read from a distance.

Fully Configurable for Your Application:
RTC-700 models provide a choice of basic or advanced functionality, with an optional sensor under test input, dynamic load compensation sensor input, external sensor input and custom-built smart reference sensors for increased accuracy.
A wide well diameter and a broad range of interchangeable single or multi-hole inserts suit almost any metric or imperial-sized sensor under test.
An integrated support rod kit protects cables, provides stable mounting and ensures a fixed immersion depth for delicate, long or heavy sensors.
A custom-built carry case with trolley offers increased portection, security and accesssories storage.

Lightweight, Portable and Versatile:
Weighing only 11.3kg, the RTC-700 is designed for easy transporting and positioning.
A wide operating temperature range of 0 to 40°C allows operation in harsh conditions.
Silent operation mode enables use in noise-sensitive environments.
