Ametek Jofra ITC-320A
Dry Block Temperature Calibrator

The ITC series employs the slim and rugged design of the CTC series. This series also features the intuitive user interface, the clear LCD display, and the functionality that is used in the successful CTC series. However, the ITC is designed with the state-of-the-art dual-zone heating block and MVI circuitry that has been adopted from the ATC series. The MVI circuitry ensures stable temperatures even when the mains supply is unstable. The ITC series is designed for both on-site and maintenance shop use. The applications are generally critical process control but can vary based on calibration and testing requirements. The ITC series dry-block calibrators are available in 3 different temperature ranges and all models are equipped with RS-232 serial communication capabilities. The units are supplied with the AMECAL-TEMPERATURE software package. Three models - The JOFRA ITC series consists of three different models which differ in temperature range. All units offer similar features and the large, backlit LCD display panel, which is easy-to-read even in well-lit areas. A rugged, slim-line, aluminium outer casing with die-cast top and bottom protects the ITC series of dry-blocks. Model and temperature range: ITC-155 -23 to 155 Deg C ( -9 to 311 Deg F) ITC-320 33 to 320 Deg C (91 to 608 Deg F) ITC-650 33 to 650 Deg C (91 to 1202 Deg F) ITC-320 & ITC-650 dual-zone heating block The specialized block design increases the temperature homogeneity in the critical calibration zone. It also minimizes the need to insulate the sensors-under-test and makes it possible to calibrate liquid-fi lled and other mechanical sensors. The main, or lower, zone ensures optimum heat dissipation Well - optimized for speed - The special designed heating block profile reduces the mass so it heats up and cools down very quickly. The design still offers good stability and accuracy. High flexibility - You are not limited by fixed holes. Interchangeable insertion tubes are used to match the diameter of your sensor-under-test. Also multihole inserts are available. Stability indicator - Clear audio and visual indication in the display when the calibrator is stable. FEATURES: Dual Heat Zone Stability Technology Multi-hole Interchangeable insertion tubes Automatic switch test RS 232 and calibration software Multi information display Safty banana bushings Timed Stable Auto stepping Stability indicator Count down timer (shows when unit is stable) Programmable maximum temperature Fast simulation/training mode Re-calibration from keyboard Easy-to-use - Intuitive operation - All instrument controls may be performed from the front panel. The heat source is positioned away from the panel. This design helps to protect the operator. The main functions on the ITC series are designed with one-key-one-function logic. This means that there are no sub-menus or difficult to remember multiple keystrokes necessary to access primary functions. The easy-to-read, backlit display features dedicated icons, which help in identifying instrument conditions and operational steps. Set temperature - The Up and Down arrow keys allow the user to set the exact temperature desired with a resolution of 0.1 C or F. Instrument setups - The ITC series stores the complete instrument setup, including: engineering units, stability criteria, resolution, display contrast, slope (ramp) rate, auto step settings, and maximum temperature. Automatic switch test - Operators can save a lot of time using the automatic thermoswitch test function to find values for the Open and Close temperatures. Additionally, this feature displays the hysteresis (deadband) between the two points. The feature ensures a very high repeatability when testing thermo-switches. Simply press the SWITCH TEST key to activate the function. Maximum temperature - From the setup menu, the user can select the maximum temperature limit for the calibrator. This function prevents damage to the sensor-under-test caused by the application of excessive temperatures. Re-calibration/adjustments - The ITC series has a very easy and straight forward procedure for re-calibration/adjustment. There is no need fora screwdriver or PC software. The only thing you need is a reliable reference thermometer. Place this reference probe in the calibrator and follow the instructions on the display. Simplified calibration documentation - All JOFRA ITC- instruments are supplied with RS232 computer interface and the calibration software AMECALTEMPERATURE software. This WINDOWS©-based software allows the user to customize his or her calibration routines. The software is easy-to-use so you do not have to be a programmer to confi gure your own calibration procedures. The software features prompts, menus, and help functions that guide you through the confi guration process. The AMECAL-TEMPERATURE software supports automatic calibration for all JOFRA dry-block calibrators equipped with an RS-232 serial data interface including the JOFRA DTI-1000 digital thermometer. For semi-automatic calibrations, the software also supports liquid baths, ice points, or other dry-block heating and cooling sources. Using the software's "SCENARIO" function allows for combining instruments in virtually any configuration. The calibration data collected may be stored on a PC for later recall or analysis. A family of inserts are available for the ITC calibrator. The most common Multi-hole models are shown below:
