Handheld temperature calibratorTC 6621 / TC 6622

Measurement and occurrence

Protection for on-site use

The perfect instrument for control and testing

User friendly and durable, these tools are designed to simplify temperature transmitter and probe maintenance and commissioning operations.

They measure and generate thermocouples and RTDs.

L is well suited for different processing tasks due to their range and special features such as scaling, ramping

High precision: 0.02% of reading readings

Very low temperature coefficient: 10 ppm/° C for thermocouples and 7 ppm/° C for resistors, even under harsh external environmental conditions, the accuracy remains unchanged.

Measure and simulate 14 types of thermocouples and 12 types of RTDs.

calibratorTC6621andTC6622Using a graphical display makes programming and reading easier.

Process transmitters and other sensors are becoming increasingly reliable and accurate, so the performance of calibrators needs to be at the same level.

That's why we supply instruments with an accuracy of 0.02% for on-site use of thermocouples and RTDs. The resolution can be programmed by the user for better reading: it can reach 1m Ω or 1 μ V.

Simulation function:

Simple and cyclic slope

By using TC6621 and TC6622, slopes can be generated, with low and high widening, rise and fall times, stability and delay times set. The delay time (programmable between 1 and 3600 seconds) allows a single user to initiate a ramp and go to the control panel.

Loop slope parameters

Synthesizer mode:This mode allows sending values of predetermined programmable frequencies.

Ladder mode: This mode allows sending programmable amplitude and frequency values.

Zoom ratio: This operation allows for correction of probe errors. The execution of scaling is used up to 10 segments to fit the actual calibration values.

Measurement function:

Calibrate sensors:A database can be created for designing curves using the correction values displayed on the calibration report for calibrated sensors.

Zoom ratio:This operation allows for correction of probe errors. The execution of scaling used up to 10 segments to fit the actual calibration values.

Data recording:The recording of data can be done manually on events or automatically using programmable frequency values. The data is marked with time and can be displayed in the form of a list or curve.

Other functions:

Interface language:TC has 5 languages: French, English, German, Italian, and Spanish.

Display contrast:When in dark conditions, users can modify the contrast of the display and turn on the backlight of the display. The backlight timer can be programmed and controlled.

Display resolution:Users can choose from three resolutions (up to three decimal places): high, medium, or low resolution.

Date and time display:These are displayed on the screen unchanged in formation.

Statistical function:At the bottom of the screen, display the maximum, average, and minimum values of the measured values. The reset function allows for the recalculation of values.

Maintain:Freeze the monitor.

wave filter:A filter can be applied in a short amount of time to eliminate fluctuations in values.

Built in software updates:Based on the improvements of these calibrators, the manufacturer offers you the freedom to change and update your instrument using a USB port.

Delay function:When simulating stairs and slopes, this feature allows for delayed start.
