The Isotech 991 Tympanic Thermometer Checker provides an innovative, portable solution for validating ear thermometers (tympanic thermometers). This device is designed to overcome the challenges of traditional calibration methods. Old-fashioned methods such as using a stirred water bath, which are often bulky, expensive and difficult to move, are an obstacle for many medical facilities. In contrast, the Isotech 991 provides a cost-effective and easily transportable option for regularly calibrating and checking thermometers, even outside of a laboratory environment.

Range

The Isotech 991 operates in a temperature range of 20°C to 50°C and offers an exceptional accuracy of ±0.01°C. This makes it ideal for calibrating ear thermometers used in hospitals, clinics and other medical settings. The device is equipped with an emission aperture of 12 mm in diameter, with a high emissivity of approximately 0.999. This ensures that the device delivers highly reliable measurements even in challenging conditions.

Ease of use

One of the biggest advantages of the Isotech 991 is its portability and ease of use. The device is compact in size, measuring 200 mm high, 135 mm wide and 170 mm deep, and weighs only 2.3 kg. This makes it easy to carry and use in a variety of environments, from clinics to field conditions. Unlike traditional methods, which often require special equipment and training, the 991 can be operated without specialized training. This makes it a perfect choice for quality control and quick thermometer checks, even by users with no technical background.

The device is equipped with a three-color LCD display that clearly shows both the current temperature and the set temperature. The user interface is intuitive, allowing the user to easily set up the device and quickly perform reliable measurements. In addition, the Isotech 991 offers the ability to lock and password protect the set temperature, preventing unwanted adjustments. The device starts up automatically, without the need for user intervention, and performs self-tests to ensure stable and reliable operation.

In terms of technical performance, the Isotech 991 offers an accuracy of 0.5°C in the temperature range of 20°C to 42°C, and 0.7°C in the range of 42°C to 50°C. The device can be easily connected to a PC thanks to the included RS422 interface, and with optional accessories such as an RS232 converter cable, communication with other systems can be extended. This makes the device suitable not only for standalone use, but also for integration into more complex calibration and quality control systems.

Suitable for medical applications

The result is a product that is not only user-friendly and portable, but also delivers the precision required for medical applications. The Isotech 991 is calibrated between 20°C and 43°C using the NPL Primary Ear Thermometer Calibration (PET-C) source, guaranteeing consistent and reliable measurement results. Although the NPL certification applies only to the prototype, the Isotech 991 still provides a high-quality measurement standard for everyday use situations.

The Isotech 991 is especially useful for medical institutions that need regular quality control of ear thermometers but want to avoid the high cost and complexity of complete laboratory setups. Whether checking new batches of thermometers or performing routine checks between calibrations, the Isotech 991 delivers the accuracy and reliability needed in an easy-to-use and transportable device.

For medical professionals looking for a reliable and affordable way to check thermometers, the Isotech 991 is an excellent choice. It combines advanced technology with a practical and cost-effective approach, making it ideal for use in a variety of medical and clinical settings.
