Functions and Features of Dearto Calibration Bath

1. Intelligent precision calibration Bath

DTS-CT intelligent calibration bath is a new type of intelligent self-control temperature verification device launched by our company. It adopts touch screen control and operation, a completely intelligent human-machine interface, and the operation is more convenient, simple and practical. The structure adopts double-chamber side stirring technology. The calibration bath achieves an ideal uniform temperature field through intelligent PID adjustment. It meets the needs of various low-temperature thermocouples, industrial thermal resistance, pressure thermometers, bimetal thermometers, glass liquid thermometers and other temperature sensors. Verification/calibration work.

Functional advantages:

1. The temperature control rate is adjustable, the heating rate can be set freely, and the heating rate can be set according to the actual verification or calibration. The temperature rises at a uniform speed to meet the verification/calibration of various temperature switches.

2. Real-time curve display, automatic calculation of volatility, multi-touch can be freely zoomed and panned, and the volatility can be customized for a time period. stable duration.

3. Composite heat insulation design, more effectively blocking thermal bridges, multi-layer composite heat insulation structure to ensure better temperature field stability and fluctuation

4. Double sensor overheat protection, over temperature automatically cut off the power

Independent overheating monitoring hardware. Double safety protection of software and hardware

5. Possess an active smoke exhaust system to create a healthy working environment. Compatible structural design, flexible for various smoke exhaust scenarios

6. Support USB, WIFI, WLAN, serial communication functions

7. Intelligent automatic rehydration. Real-time monitoring by multiple liquid level sensors, intelligent automatic rehydration to prevent dry burning. Oil bath level alarm.

8. Ergonomically designed, the temperature control screen is installed with a shaft mechanical cantilever, and the angle and length can be adjusted at will. It is easy to operate.

2. Ultra-portable intelligent refrigerated calibration baths

DTS-B refrigerated calibration bath is a high-precision self-control temperature verification device, which has the characteristics of good temperature stability, uniform temperature field, and high temperature control accuracy. It adopts fully enclosed compressor refrigeration system and intelligent PID adjustment to realize automatic temperature control. The bath body is compact in structure, light in weight, easy to carry and durable. It is suitable for on-site verification/calibration of temperature sensors such as various industrial thermal resistances, low-temperature thermocouples, armored thermocouples, working liquid-in-glass thermometers, standard mercury thermometers, bimetallic thermometers, pressure thermometers, etc.

Functional advantages:

1. 10-35C ambient temperature guarantee index

2. It takes 30 minutes for 150C to drop to 25C. The high temperature drops quickly to meet the user's temperature hysteresis test or multiple rounds of verification on the same day.

3. Ultra-wide temperature range from -40 to 180c, no need to replace the medium.

4. Rapid sealing design, anti-leakage, convenient transportation

4. Hidden handle, convenient and easy to carry.

5. Smart touch screen design.

6. The company can display the temperature curve and fluctuation data in real time.

7. Fully automatic segmental temperature control. Rapid temperature rise "zero" overshoot.

8. Microcirculation technology. The temperature field is uniform and stable.

9. Support multi-point temperature correction, and the lamp can correct the temperature sensor in multiple points.

10. With overheat protection and temperature rise limit function, it is safe and reliable.

11. Equipped with RS-232 communication interface, M is connected to the upper computer.
