Metrology-Level Performance and Dual-Zone Control

The Additel ADT875 series redefines expectations for portable temperature calibration with its metrology-level performance in stability, uniformity, accuracy, and loading effect. These dry well calibrators achieve exceptional precision across their broad temperature ranges. The ADT875-155 model offers control from -40°C to 155°C with a display accuracy of $\pm$0.18°C at Full Range, and impressive stability of $\pm$0.01°C. The ADT875-350 covers 33°C to 350°C with $\pm$0.2°C accuracy and $\pm$0.02°C stability. For higher temperatures, the ADT875-660 ranges from 33°C to 660°C with accuracies up to $\pm$0.3°C and stability up to $\pm$0.04°C. Crucially, the series incorporates dual-zone control technology. This innovative design ensures superior axial and radial uniformity within the well, minimizing temperature gradients and providing a more stable environment for the sensors being calibrated. This robust thermal management, combined with exceptionally low loading effects (e.g., $\pm$0.02°C for external sensors on the 875-155), guarantees highly reliable and repeatable calibration results, even when multiple sensors are inserted, making it an invaluable tool for precision temperature metrology.

Portability, Speed, and Wide Temperature Range

Engineered for the demands of both laboratory and field use, the Additel ADT875 series stands out for its exceptional portability, ruggedness, and quick to temperature capabilities. The calibrators boast impressive heating and cooling times, significantly reducing the waiting period during calibration cycles. For instance, the ADT875-155 heats from -40°C to 155°C in just 13 minutes and cools from 155°C to -40°C in 28 minutes. The ADT875-350 heats to 350°C in 10 minutes, while the ADT875-660 reaches 660°C in 15 minutes. This rapid thermal response maximizes throughput and enhances overall productivity in any calibration environment. The compact size (e.g., 320 x 170 x 330 mm) and manageable weight (9.9 kg for 875-155, 8.6 kg for 875-350/660) ensure these units are easy to transport and set up, making them ideal for on-site calibration. This balance of broad temperature range, rapid thermal dynamics, and inherent portability makes the ADT875 series a highly efficient and versatile solution for diverse temperature calibration needs.

Comprehensive Process Calibrator Option for Efficiency

A key differentiator for the ADT875 series is its optional built-in process calibrator, which significantly streamlines field operations and reduces the need for multiple instruments. This integrated feature provides a multi-channel readout for a reference thermometer, RTDs, and TCs, allowing technicians to connect and monitor various temperature sensors simultaneously. Beyond simple measurement, it supports task documentation, enabling users to record calibration data directly on the device, promoting a paperless workflow and improving data integrity. Furthermore, this option includes a full HART field communicator, allowing for seamless configuration, diagnostics, and calibration of HART-enabled smart temperature transmitters without requiring a separate handheld device. This powerful combination transforms the dry well into a complete, self-contained temperature calibration workstation, capable of managing a wide array of calibration tasks efficiently, from simple sensor verification to complex transmitter commissioning, all from one portable unit.

Diverse Applications in Critical Sectors

The unparalleled accuracy, dual-zone control, and versatile features of the Additel ADT875 series dry well calibrators make them indispensable tools across an extensive spectrum of industries and highly specialized applications where precise temperature measurement and control are paramount. In calibration laboratories, they serve as high-performance working standards for the precise calibration of PRTs, RTDs, and thermocouples, ensuring traceability and maintaining measurement integrity. For pharmaceutical manufacturing and biotechnology, their ability to precisely control and verify temperatures is crucial for validating processes in bioreactors, fermenters, and storage facilities, ensuring strict regulatory compliance and product quality. In the food and beverage industry, they are used for calibrating temperature sensors in critical control points within production lines, ensuring consistent cooking, cooling, and storage temperatures for quality control and adherence to food safety standards. Energy and power generation plants rely on them for calibrating temperature sensors in turbines, boilers, and heat exchangers, optimizing operational efficiency and preventing hazardous conditions. Furthermore, in aerospace and automotive testing, they are vital for calibrating temperature sensors used in engine testing, environmental chambers, and material characterization, where extreme temperatures must be precisely controlled and measured. The ADT875-155’s specific compatibility with the Additel 110 series short probe calibration kit makes it ideal for calibrating temperature probes and transmitters with challenging short lengths, commonly found in hygienic applications. This broad applicability, combined with features like set point control by reference and the self-calibration feature, ensures consistent, high-quality results across all these critical sectors.
