The new Additel ADT835 portable calibration bath: advanced technology for temperature calibration

In the world of metrology and calibration, precision is not an option, but a necessity. The new temperature calibrator Additel ADT 835 represents the evolution of professional calibration, offering high performance and extraordinary operational flexibility. This portable calibration bath, designed to meet the needs of the most demanding sectors such as pharmaceutical, biotechnological and food, combines speed, stability and multiple management capacity in a single cutting-edge tool.

Equipped with advanced temperature control technologies, an advanced cooling system and numerous intelligent functions, the Additel ADT835 is designed to optimize every step of the calibration of temperature sensors, even in critical environments and with rigorous requirements. A true ally for those seeking maximum efficiency and certified precision, now available in the E Instruments catalogue.

Faster calibration cycles with the ADT 835

When it comes to calibration efficiency, three elements make the difference: short thermal transition times, rapid temperature stabilization and large bath capacity.
The Additel ADT835 was designed to excel in each of these aspects, integrating advanced technologies such as variable speed predictive regulation and overshoot-free control.

During the heating or cooling process, the device maintains an error band of ±0.1°C, ensuring precise temperature control at all stages. This translates into significantly faster calibration cycles compared to traditional baths, with a direct impact on productivity: less time for each calibration, more efficiency in the laboratory or in the field.

Precise calibration also for special and sanitary sensors

In the pharmaceutical, biotechnology and food sectors, the calibration of temperature sensors can present significant difficulties: short probes, large flanges or sanitary fittings often make traditional dry blocks inadequate. This leads to additional costs, customized solutions and, in many cases, less than optimal results.

The ADT 835 resolves these critical issues thanks to its stable and uniform calibration bath, which easily accommodates sensors of different shapes, lengths and dimensions. Its structure is designed to eliminate the need for tailor-made adaptations, offering precise and repeatable results in a simple and immediate way. It is the ideal answer for those who work with healthcare or non-standard equipment, without compromising the quality of the control.

Maximum efficiency in batch calibration

Reducing downtime is a priority in every industrial process. For this reason, the ADT835 was designed to maximize efficiency in multiple calibrations, allowing you to work on multiple sensors simultaneously, even in complex production environments.

With an internal capacity of 90 mm x 90 mm and a depth of 155 mm, the bathroom can handle up to 4 50 mm diameter sanitary sensors or 40 6.35 mm rod sensors in a single operation. This means fewer cycles, greater productivity and a drastic reduction in calibration times compared to traditional calibration baths.

The ADT835 not only accelerates the process, but standardizes operations, increasing the consistency of results and optimizing the resources of the laboratory or technical department.

Dual zone heating technology: stability even in difficult conditions

In the real world, industrial settings are far from ideal: power surges, irregular airflows, or sudden environmental changes can compromise calibration accuracy.
The ADT835 addresses these challenges with an innovative dual zone heating technology.

This solution combines:

• An external heating system, positioned near the steam chamber, to ensure stable and uniform temperature control.
• An internal heating element, immersed directly in the fluid, which reacts quickly and precisely to variations.

Thanks to this advanced design, the bath maintains a constant and reliable temperature even in complex environments, making it perfect for use in the field or in industrial plants with variable conditions.

Integrated multifunction calibrator: three channels for maximum versatility

One of the most interesting options offered by the ADT835 is the possibility of integrating a high-precision multifunction process calibrator, with three independent channels. This feature eliminates the need to bring multiple tools into the field, simplifying technicians' work and increasing productivity.

The integrated calibrator includes:

• Precision thermometer;
• Multimeter;
• 24V power supply;
• Integrated HART communicator.

The first channel is dedicated to the reference sensor, compatible with both intelligent PRT probes and user-supplied thermometers. The other two channels are intended for devices under test (DUT) and support a wide range of instruments: resistance thermometers (RTDs), thermocouples (TCs), temperature transmitters, switches and HART devices.

All channels are equipped with quick pressure connectors, which allow a simple and safe connection, without the need for tools. A perfect solution for those looking for efficiency, precision and practicality in a single tool.

Automatic calibration of the internal sensor: more precision, fewer complications

Maintaining precision in temperature control is critical for every calibration bath. However, traditional calibration methods can be long and complex, requiring manual records and detailed calculations for each calibration point.

The ADT835 solves this problem with a integrated self-calibration program for its internal reference sensor. This system allows you to automate the entire process, eliminating manual errors and drastically reducing the time needed to guarantee the accuracy of the instrument.

With this function, the bath maintains high performance over time with minimal interventions by the operator, simplifying management and increasing overall reliability in calibration activities.

Intelligent remote control for simplified management

To maximize operational efficiency, the Additel ADT835 offers advanced remote control features, designed to simplify remote management and optimize workflows.

Two operating modes are available:

• Point-to-point mode: direct connection of the bathroom to a smartphone or computer via Bluetooth or WiFi hotspot, for immediate control even in the absence of a local network.
• Cloud mode: connecting the device to the network via WiFi or LAN port, which allows centralized and simultaneous management of multiple calibration baths from any enabled device.

Thanks to these options, the ADT835 adapts perfectly to modern environments that require flexibility, continuous monitoring and remote operation, reducing downtime and improving the organization of calibration operations.

Intelligent design and operational safety first

The Additel ADT835 is not just about performance: it is designed to guarantee safety, ease of use and simplified maintenance at every stage of use.

Its fluid protection system includes:

• A tank and a drain port for safe handling of liquids, making transportation and maintenance easier.
• A corrosion-resistant stainless steel tank, easy to clean and ideal for use even with aggressive fluids or in sensitive environments.
• A sealed lid with manual locking screw that prevents leaks during transport and protects the environment from contamination.

Security level:

• A protected power switch prevents the accumulation of oil mist on the contacts, reducing the risk of malfunctions.
• A temperature warning icon on the display is activated when the liquid exceeds 50°C, alerting the operator and preventing accidental burns.

These precautions demonstrate Additel's attention not only to performance, but also to the safeguarding of the operator and the longevity of the device.
