The signature feature of the GSP-6G is its detachable propylene-glycol bottle external temperature sensor on a 3-metre lead. The glycol bottle acts as a thermal buffer, damping rapid air-temperature fluctuations so that recorded readings closely simulate the actual temperature experienced by stored products such as vaccines. This buffered measurement is widely recommended for pharmaceutical and vaccine storage because it reflects true product conditions rather than transient swings caused by door openings or defrost cycles, providing more meaningful and defensible data for compliance and quality decisions.

Complementing the buffered probe, a separate temperature-and-humidity combined sensor on a 2-metre lead offers three measuring types that can be switched within the ElitechLog software, giving users flexibility to monitor ambient conditions alongside buffered product temperature. The device measures temperature from -40 C to +85 C, with +/-0.3 C accuracy on the temperature-humidity probe between -20 C and +40 C and +/-0.5 C on the temperature probe, plus humidity across 0 to 100 percent RH with +/-3 percent RH accuracy. With 0.1 C and 0.1 percent RH resolution and capacity for up to 16,000 temperature and 16,000 humidity data points, the GSP-6G captures detailed, long-duration records suited to demanding monitoring programmes.

• Usability and visibility are central to the design.
• A large LCD clearly presents current readings along with maximum and minimum values and alarm status, allowing staff to assess conditions at a glance.
• Multi-alarm notification - through an audible buzzer, LED indicators and on-screen warnings - ensures that excursions are noticed promptly so corrective action can be taken before products are compromised.
• Built-in magnets allow the logger to be mounted conveniently on refrigerators, cabinets and metal surfaces, keeping the display visible and the sensors correctly positioned.

• Data management is straightforward via the USB interface, with reports exportable to PDF, Excel and TXT formats through the free ElitechLog software.
• This makes it easy to archive records in quality systems, attach them to audits and inspections, or share them with customers and regulators.
• Configurable logging intervals from 10 seconds to 24 hours let users tailor the level of detail to their application, from fine-grained validation studies to routine long-term monitoring.
• The unit is powered by a 3.6 V ER14505 lithium cell or USB and operates across an ambient range of -30 C to +70 C, supporting use in cold rooms and challenging environments.

The GSP-6G is widely deployed for vaccine and pharmaceutical storage, hospital and pharmacy refrigerators, blood banks and laboratories, biologics and diagnostics, and temperature- and humidity-sensitive food storage and shipping. Its buffered-probe methodology aligns with the expectations of Good Distribution Practice (GDP), WHO vaccine storage guidance and similar quality frameworks, helping organisations demonstrate that stored products remained within validated conditions and reducing the risk of costly losses or compliance findings.

In practice, the GSP-6G is simple to deploy: mount it with the built-in magnets, place the glycol probe among the stored product and position the temperature-humidity probe as required, configure intervals and alarm limits in ElitechLog, and begin monitoring. Staff respond to any visual or audible alarms, and records are downloaded periodically for archiving and review.

Overall, the Elitech GSP-6G combines buffered glycol-probe accuracy, dual temperature-and-humidity sensing, a large informative display, robust multi-alarm notification and flexible reporting in one dependable instrument. It is an excellent choice for facilities that must protect and document the storage of high-value, temperature-sensitive goods.
