The Ametek Jofra CTC-652 dry block compact temperature calibrator is a high precision reference temperature source.

Purpose-built for field and workshop use, the CTC-652 provides the portability, efficiency and accuracy essential for time-critical industrial temperature testing and calibration.

Key Features & Specifications

Wide Temperature Range:
Operates between 28 and 650°C

Fast Heating, Cooling and Stabilisation Times:
Heats from ambient (23°C) to 650°C in 33 minutes
Cools from 650 to 100°C in 48 minutes
Cools from 100 to 50°C in 25 minutes
Reaches stability in 5 minutes

Exceptional Accuracy, Stability and Resolution:
Accurate to 0.35°C with external reference sensor
Accurate to 0.50°C with internal reference sensor
Stability of 0.05°C
Adjustable resolution of 1 / 0.1 / 0.01°C / °F / K

Deep Immersion Depth with Temperature Uniformity;
A tall 390mm body provides an extended well depth of 190mm / 7.5" to calibrate longer or liquid-filled sensors
Non-linear heating elements monitor axial and radial uniformity within the well, ensuring a homogeneous temperature for reliable calibrations

Mains Variance Immunity Circuitry:
Mains Variance Immunity (MVI) circuitry maintains stability and accuracy during power fluctuations caused by large electrical motors or heavy industrial equipment
MVI circuitry continuously monitors the CTC-652's supply voltage, making adjustments to ensure a consistent energy flow to the heating elements

Time-Saving Features:
Built-in auto-stepping and switch test functions automate routine procedures, saving time and streamlining operations

Fully Configurable for Your Application:
CTC-652 models provide a choice of basic or advanced functionality, with an optional external sensor input and custom-built smart reference sensor 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
A support rod kit protect cables and provides stable mounting for delicate, long or heavy sensors while ensuring a fixed immersion depth
A custom-built carry case provides increased portection, security and accesssories storage

Lightweight, Portable and Versatile:
Weighing only 9kg, the CTC-652 is easy to transport and position
A wide operating temperature range of 0 to 50°C allows operation in harsh conditions
Silent operation mode allows use in noise-sensitive environments

Delivered Ready for Immediate Operation:
Every Jofra CTC-652 is delivered as standard with:
Heat shield
Test leads
JofraCal calibration software
USB cable
Insert removal tool
Mains power cable
Calibration certification
Manuals
