Jofra CTC140A temperature calibrator

CTC series industrial dry calibration instrument

Jofra CTC series industrial dry temperature calibrator is very suitable for use in the field, the calibration process is fast, reliable, and has MVI function and supporting software. Portability and calibration speed are significantly better than the liquid tank, and do not use the liquid, while a wider temperature range. CTC dry temperature calibrator can calibrate thermal resistance, thermocouple, temperature switch, as well as other universal temperature sensors.

Product performance

CTC series with strong and lightweight design, suitable for field use, panel design simple and intuitive, the screen with a background light LCD lcd. The user interface is friendly and intuitive, and the key operation is simple and easy to use. The current status is displayed on the screen. The shell is made of aluminum material durable.

CTC series includes 6 models, corresponding to different temperature range. All models have RS-232 interface, AMECAL-LIGHT calibration software for standard configuration.

The casing can be replaced, and the casing can be selected according to the size of the sensor

Enhanced stability

MVI circuit ensures the stability of the temperature in the supply voltage fluctuations

Time saving automatic function

Automatic switch test and automatic stepping function

Data processing function

RS232 communication interface and AMECAL-LIGHT software are standard configuration

Pitel effect (CTC-140A)

Pitel effect, Jofra CTC-140A temperature calibrator

In 1834, French physicist JEAN PELTIER found that the circuit is connected to the thermocouple can be observed on "reverse effect": the end of thermocouple thermocouple absorbs heat and the other end of the heat release. This is Pitel Pitel. The actual effect element (electronic heat pump) includes many connected arranged in parallel circuit in semiconductor materials. These thermoelectric elements and their electrical connection is fixed between the two ceramic plates. The ceramic plate used for fixing the whole structure and the insulation between the elements.

Intuitive simple operation

Intuitive simple operation, Jofra CTC-140A temperature calibrator

All functions can be operated directly on the panel, heating area design position and operation panel separation, so as to protect the operator. The main function of CTC is a key corresponding to a function, no complicated menus. The LCD display is clear and easy to read, and the current state of icon prompts.

Operation and setting

Fast through the up and down arrow keys to set the temperature of 0.1 DEG C. In addition, the resolution can also set the unit stability standard, display resolution, contrast, slope (heating rate), automatic step set and maximum temperature setting.

Stability indicator

When the calibration instrument reaches the set temperature and number of a bold will remain stable on the screen after the sign. The operator can change the stability conditions to achieve more stringent calibration results. 5 minutes before the calibration to achieve stability, there will be a countdown sign to achieve a stable time.

Automatic switch test

Automatic switch test, Jofra CTC-140A temperature calibrator

The use of automatic switching test function to record the temperature of the temperature of the opening and closing of the switch can save calibration time. And can also display the dead value between two points. Just press the switch test key can be automatic switch test.

Automatic stepping

Up to 9 steps can be set up automatically, including the stability of each step. This feature allows the CTC to be placed on the site to automatically control the temperature, the operator can observe the sensor data in the control room.

Recalibration and adjustment

The new CTC calibration method is very simple, no software or screwdriver, only need a standard reference thermometer. The reference thermometer is inserted into the instrument, in accordance with the instructions on the screen can be re calibrated. A lot of Metrology departments or calibration laboratories can do this work, and can issue calibration certificate.

Liquid filled sensor (pressure thermometer) or temperature switch

CTC-320B and CTC-650B have a higher 190mm insertion depth and can be calibrated with a liquid filled thermometer. CTC-650B has a specially designed nonlinear heating element and a larger size of the casing, so that the whole heating temperature is highly consistent. This allows the entire length of the sensor parts are placed at the same temperature, resulting in high calibration accuracy and repeatability.

Calibration software

All CTC with RS232 interface and AMECAL-LIGHT software. This software is a WINDOWS application software, you can set different calibration procedures, simple and intuitive operation. This software can print calibration reports in accordance with ISO-9000 specifications. AMETEK-LIGHT software support all RS232 interface with the JOFRA body calibration instrument including JOFRA DTI1000 high precision thermometer. In semi-automatic calibration applications, the software can also support the liquid trough, such as freezing point.
