Fast Temperature Calibration
The MTC-650-A contains an innovative heating block profile, which heats up to 650°C / 1202°F in only 18 minutes. The special heating profile minimizes mass and yet, still accepts an insertion tube with a 1 in (26 mm) outer diameter. It’s the perfect compromise between temperature stability, homogeneity and rapid heating and cooling.
Easy to Read, Intuitive Operation
The MTC-650-A temperature calibrator is simple to operate. Access to the most commonly used functions such as Set, Preset, Switch test and Auto step is only one click away. An easy-to-read and very informative colour display offers a full overview of the calibration task you are currently performing. The editable fields are marked in light blue. Navigating is fast and easy using the arrow keys and the enter key.
Multi-informational Display
The colour display is easy to read and very informative that gives a full overview of the calibration task you are currently performing.
The display contains information at a glance, such as:
- Status bar – showing information about the recalibration due status, hot and cold safety warnings, date and time
- Calibration settings – the calibration settings and stability criteria for the reference sensor. Can be accessed and changed directly in the display by use of the arrow keys.
- Calibration status – displays the current status of the calibrator, like heating or cooling, expected time to stability, or stability achieved.
- Function bar – shows the current possibilities if the function keys
- Function keys – the function keys serve as shortcuts to the main functions like Set, Pre-set, Auto step and switch test. When entering one of the functions, the function keys will then show the options within the selected function.
Useful Features
The MTC-650-A is very versatile calibrator with many integrated functions – you can run the calibration in four different ways.
- Set function
- The fastest and simplest way to use the calibrator. Simply press Set and type in the desired temperature and off you go.
- 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. You can decide if you want the deadband or not and the test can be repeated automatically in the up to three subsequence runs.
- Pre-Set Mode
- Pre-set mode, you activate one of the pre-set temperatures. The pre-sets are programmable for your specific needs.
- Auto Stepping
- In AUTOSTEP mode, you 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 supplies are a major contributor to calibration inaccuracies. Traditional temperature calibrators often become unstable in Industrial environments where electrical motors, heating elements and other devices are periodically cycled on and off. The cycling supply can cause lower quality temperature regulators to perform inconsistently, leading to both inaccurate reading and unstable temperatures. The MTC-650-A 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.
JofraCal Calibration Software
The MTC-650-A is supplied with the highly versatile calibration software JofraCal. All calibrations can be documented with a certificate, given that the MTC-650-A is controlled for a PC. When the calibrated has reached the desired temperature and stability it will prompt you to type in the UUT temperature. JofraCal documents all your calibration needs.
