Best in class industrial calibrator

Joftra CTC-1205 temperature calibrator is the most accurate high temperature industrial class temperature calibrator on the market.

Wide temperature range

The CTC-1205 covers a wide temperature range from 100 to 1205°C (212 to 2201°F). This makes it sufficent to cover all standard industrial temperature calibration applications.

Fast calibration

Jofra CTC-1205 provides a very fast heating time and even offers a cooling time reduced with 62% compared to the previous version, CTC-1200. The CTC-1205 offers an outstanding stabilization time. Performing a three-point temperature calibration procedure is fast and saves time.

External reference sensor ensures full documentation

All our C Models are designed with a signal input for an external reference sensor. When users order the CTC-1205C including the STS-TC reference sensor, the package will include a full system calibration certificate as well as certificate for the block.

External sensor control

The CTC can be run in two modes when using the external reference sensor. External Ref mode: The external reference sensor represents the True value. Set Follows True mode: The reference sensor serves two purposes; measuring the reference temperatue and at the same time controlling the block temperature to the set temperature.

Easy to carry

The CTC series is designed for calibration on-site as well as in the maintenance shop. We have focused on great portability in regard of size and weight. CTC-1205 weighs 40% less than CTC-1200. The calibrator is lightweight and easy to carry and with a rugged handle placed away from the heat-zone.

Multi-Information Display

Status Bar

Shows information about recalibration due status and hot/cold safety warnings and keeps track of date and time.

Calibration Settings

Shows the actual calibration settings for reference sensor and stability criteria. Can be accessed and changed directly in the display by use of the arrow keys.

Calibration Status

Shows current status of the calibrator, like heating/cooling, stabillity achieved and expected time to stability.

Function Bar

Shows the current possibilities of the function keys.

Function Keys

The function keys serve as shortcuts to the main functions like Set, Preset, Auto step and Switch test. When entering one of the functions the function key shows the options within the selected function.

Informative color display and

intuitive operation

The CTC series is designed with an easy to read and very informative color display that gives users a full overview of the calibration task they currently are performing.

Useful Features

The CTC-1205 is a very versatile calibrator with many integrated functions - users can run the calibration in four different ways.

Set function

The fastest and simplest way of starting the calibrator. Simply press SET and type in the wanted temperature.

Auto Switch Test

Switch test calibration is a perfect time saver. Start the switch calibration and come back to note the results after the test. Users decide if they want the deadband or not - and the test can be repeated automatically in up to three subsequent runs.

Preset mode

In PRESET mode users can activate one of the preset temperatures. Naturally the presets are programmable for the user's specific needs.

Auto Stepping

In AUTOSTEP mode users can program as much as 12 temperature steps and at the same time set the dwell time. Even the stability criteria can be programmed. Just start the sequence and the calibrator will run through the steps.

MVI - Mains Power Variance Immunity improves temperature stability Unstable mains power supplies are a major contributor to calibration inaccuracies. Traditional temperature calibrators often become unstable in industrial environments where large electrical motors, heating elements, and other devices are periodically cycled on and off. The cycling of supply power can cause lower quality temperature regulators to perform inconsistently, leading to both inaccurate readings and unstable temperatures. The CTC series employ the MVI, thus avoiding such stability problems. The MVI circuitry continuously monitors the supply voltage and ensures a constant energy flow to the heating elements.

Special Features

Multi sensor calibration

Insert heat loss due to mass loading from multiple or large sensors can be a challenge for most dry-block calibrators. The CTCs advanced feedback algorithms combined with the external reference sensor effectively addresses these challenges and makes the accuracy even better.

IRI - Intelligent Recalibration Information

When switching on the calibrator or connecting thereference sensor, the calibrator immediately warns users if any of the calibration certificates are overdue. A buzzer and warning appears. The recalibration interval can be set from 1 to 99 months.

Plug and Play reference sensors

STS-TC reference sensors are plug and play as they contain information in the connectors memory chip: Sensor coefficients, Unique serial number, Temperature range, Calibration date, Calibration interval

Broad range of inserts

The CTC series offers a broad range of inserts to match almost any unit under test diameter. The CTC-1205 has the same insert dimensions as the CTC- 1200, so existing insters can be re-used. For flexibility AMETEK can design special multihole inserts (3-holes) with the most common sensor diameters.

Reference sensor protection

The CTC will be blocked if it is set to a temperature outside the reference sensors specifications. This protects the reference sensor from being damaged.

User Specified Settings

Fast or silent mode calibration

The CTC-1205 calibrator can be programmed to run in silent operation. This function is an advantage if calibrating in a laboratory or an office. If used in silent operation the calibrator is not using its full cooling potential.

Support rod set

The support rod can be mounted on all CTC calibrators. It is used to hold the sensor under test in its position while calibrating. Indcludes rod, sensor grip and fixture. It is highly recommendable to use the original support rod set when using the STS-TC reference sensor.

Online firmware upgrade

Users can download firmware and software upgrades online. Users can register their product so that they can be notified when there is a firmware upgrade or other useful information regarding the instrument.

Protective carrying case

Our special designed protective carrying case gives excellent protection for the CTC calibrators. It has compartments for inserts, cables, manuals, plugs etc.

Calibration software included

The CTC is supplied with our highly versatile calibration software JofraCal. All calibrations can be documented with a certificate, provided that the CTC is controlled from a PC. When the calibrator has reached the desired temperature and stabillity it will prompt users to type in the UUT temperature. JofraCal documents all calibration needs within temperature, pressure and process calibration.
