Do you find yourself using multiple instruments just to complete one calibration task?
Traditional calibration setups often require multiple signal sources for voltage, current, frequency, resistance, temperature, and power—slowing you down and increasing error risk.
Is your current calibrator falling short on accuracy or stability?
Many calibrators can' t meet the precision demands of modern electronic instruments. Short-term drift, temperature sensitivity, and limited resolution compromise measurement confidence.
Tired of outdated systems with bulky designs and poor maintenance support?
Cumbersome form factors, inconsistent module structures, and slow turnaround times for repair or upgrades cost time and money.
Concerned about overspending on features you don' t need?
Some systems bundle hardware and software into expensive packages, making you pay for unused functions.
TUNKIA Multifunction Calibrator Series: Precision, Flexibility, and Simplicity—All in One
TUNKIA' s multifunction calibrators are purpose-built to eliminate these challenges. Our calibrators cover the full range from 3½-digit handheld multimeters to ultra-precise 8½-digit instruments, making them ideal for use in national metrology institutes, power utilities, research labs, and production lines.
TUNKIA multifunction calibrator series is a true all-in-one solution—capable of outputting DC/AC voltage, current, resistance, frequency, power, thermocouple, RTD, and process signals. Say goodbye to switching between instruments. With TUNkIA's product, you can calibrate digital multimeters, clamp meters, power meters, analog meters, temperature instruments, and even nanovoltmeters—all from a single device.
Product Classification
TUNKIA multifunction calibrators are grouped into three classes based on DC voltage accuracy—from entry-level models to elite precision instruments. No matter if you need a cost-effective workhorse or a high-end flagship, there’s a TUNKIA calibrator designed for you:
High-grade standard calibrator: TH1950
Standard calibrator: TD1880
Working calibrators: TD1850, TD1855, TD1858, TD1860, TD1870
What Sets TUNKIA Apart?
1. High Accuracy Across the Lineup
On the one hand, the TH1950 model delivers an industry-leading DC voltage annual uncertainty as low as 3.7 ppm, setting a benchmark for high-end calibration devices. On the other hand, all other models in the series are optimized to achieve top-level accuracy within their respective digit ranges—from 3½-digit to 6½-digit DMMs—ensuring reliable performance across a wide spectrum of calibration tasks.
Whether calibrating low-precision instruments or ultra-precision equipment, TUNKIA’s calibrator series consistently delivers outstanding accuracy to meet diverse application needs. Its high-precision capabilities not only enhance calibration reliability but also help users improve device performance and ensure high-quality measurement outcomes.
2. Outstanding Stability You Can Rely On
In addition to high output accuracy, TUNKIA’s multifunction calibrators also deliver exceptional output stability. For instance, the TD1880 achieves short-term DC voltage stability of up to 2.5 ppm/24 h, ensuring highly reliable performance even under demanding conditions. The output remains steady and drift-free, even when operating at high frequencies or large amplitudes, making it particularly suitable for test scenarios where dynamic output stability is critical.
Moreover, the series demonstrates outstanding long-term stability. The TD1880, for example, has successfully passed four consecutive years of type testing by national metrology institutes, with official reports validating the consistency and reliability of its output performance. This gives users strong traceability assurance and longer maintenance intervals, helping to reduce cost and operational risk over time.
3. Modular IPMA Architecture for Future-Proof Flexibility
TUNKIA multifunction calibrator series has undergone a comprehensive upgrade with the adoption of a new IPMA modular architecture. This design significantly reduces both the size and weight of the instruments through a plug-in board and data bus structure, allowing multiple units to share a common chassis and power supply. The system configuration is now more flexible, and all output modules across the series follow a unified standard—enabling independent verification, maintenance, and replacement. This greatly enhances system maintainability and traceability, shortens service turnaround time, reduces transportation and operational costs, and ultimately lowers the total cost of ownership for users.
In addition, the series incorporates a set of advanced core technologies. These innovations ensure the creation of highly stable signal sources and effectively solve long-standing issues such as power line interference, insufficient signal isolation, and instability in precision measurement environments.
4. Efficient and User-Friendly Design
From front-panel layout to software interface, TUNKIA calibrators are designed for everyday usability:
Multiple control options: Touchscreen, physical buttons, or PC-based control
One-time wiring: Simplified terminal arrangement for full-function testing
Remote diagnostics: Minor issues can be resolved off-site via remote service
5. Great Value for Every Budget
From cost-effective entry models like TD1850, to mid-range solutions like TD1870, and premium-level TH1950, our wide portfolio ensures a perfect match between performance and budget. Why pay more for features you don’t need?
