Ametek Jofra MTC-650A Marine Temperature Calibrator
The Ametek Jofra MTC-650A Marine Temperature Calibrator is a powerful, portable dry-block calibrator designed for the demanding needs of the maritime industry. It delivers fast heating, excellent accuracy, and long-term stability, making it an ideal solution for engineers who need reliable temperature calibration onboard ships and offshore installations.
The Ametek Jofra MTC range is known worldwide for quality and performance. The MTC-650A model is built specifically for marine use, helping crews maintain safety, efficiency, and compliance while reducing downtime and operating costs. As a trusted Jofra MTC Calibrator, it supports both routine maintenance and critical inspections.
Purpose-Built Marine Temperature Calibrator
This Marine Temperature Calibrator is DNV type-approved and engineered for shipboard environments where vibration, power variation, and limited maintenance time are common challenges. The Ametek Jofra MTC-650A uses advanced Mains Variance Immunity (MVI) technology to keep temperatures stable even when the ship’s power supply fluctuates.
Because of this, the Jofra MTC Calibrator delivers reliable and repeatable results in real-world marine conditions, not just in a lab setting. This makes it a dependable tool for marine engineers, service technicians, and fleet operators.
Wide Temperature Range for Marine Systems
The Ametek Jofra MTC-650A Marine Temperature Calibrator covers a wide temperature range from 28 to 650°C (82 to 1202°F). This allows one device to handle most temperature calibration tasks found onboard vessels.
From low-temperature cooling systems to high-temperature exhaust and steam systems, the Ametek Jofra MTC provides the flexibility needed to maintain many different sensors using a single calibrator.
Accuracy, Stability, and Long Calibration Intervals
Accuracy is critical in marine applications where temperature readings affect safety and performance. The Jofra MTC Calibrator offers:
- ±0.9°C accuracy with a one-year calibration interval
- ±1.8°C accuracy with a three-year calibration interval
- ±0.1°C temperature stability
These specifications allow users to choose between maximum accuracy or reduced cost of ownership. By extending calibration intervals to three years, users can lower recalibration and asset management costs by up to 66%, while still maintaining reliable performance.
This makes the Marine Temperature Calibrator a smart long-term investment for ship owners and service providers.
Fast Heating and Efficient Calibration
Time is valuable during ship maintenance. The Ametek Jofra MTC-650A features an innovative heating block design that heats quickly while maintaining excellent temperature uniformity.
The calibrator can reach 650°C in approximately 18 minutes, allowing technicians to complete more calibration tasks in less time. This balance between speed, stability, and homogeneity makes the Jofra MTC Calibrator well suited for busy marine environments.
Simple, Intuitive Operation
The Ametek Jofra MTC-650A is designed to be easy to use, even for technicians with limited calibration experience. The large colour display clearly shows:
- Actual temperature
- Set temperature
- Heating or cooling status
- Time to stability
- Stability confirmation
- Hot and cold safety warnings
One-button access to key functions such as Set, Preset, Auto Step, and Switch Test helps reduce setup time and user errors. Clear icons and safety indicators also help prevent accidental burns when the unit is hot or cold.
This simple design improves safety and efficiency when using the Marine Temperature Calibrator onboard.
Flexible Inserts and Portability
The Jofra MTC Calibrator supports a wide range of single-hole and multi-hole inserts, allowing multiple sensor sizes to be calibrated accurately. The dry-block design eliminates the need for liquids, making it cleaner and safer for marine use.
Weighing approximately 6.1 kg, the Ametek Jofra MTC-650A Marine Temperature Calibrator is easy to carry around a vessel or between work sites. Its compact size makes storage simple, even in tight engine room spaces.
