More Safety in the Cold ChainKager’s Temperature Indicators Monitor Limit Violations

The trading and consulting company Kager expands its product range with a new series of irreversible temperature indicators. These self-adhesive measuring strips provide an effective solution for monitoring temperature limits in sensitive supply chains. They are specifically designed for applications where temperature-sensitive raw materials, semi-finished goods, or final products must be protected from excessive heat. Thanks to an innovative color-change display, they not only indicate when a threshold has been exceeded but also for how long.

Precise Monitoring in Refrigerated Supply Chains

Dietzenbach, March 2025 – In the pharmaceutical, food, and chemical industries, continuous temperature monitoring is crucial to ensuring product quality and safety. Cold chains disrupted by exceeding critical temperature limits can lead to spoilage or unusability. With the new WarmMark® temperature indicators, Kager offers a simple and reliable solution to this problem. The indicators are directly attached to products or packaging and show irreversible color changes when specific temperature thresholds are exceeded.

Efficient Temperature Monitoring with WarmMark®

The WarmMark® indicators are available in different versions. A simple single-field display visualizes temperature exceedances of 8°C, 25°C, or 26°C for eight, twelve, or 48 hours. The three-field variant allows staggered monitoring of up to nine different temperature thresholds ranging from -18°C to +37°C. For example, the indicator for 10°C triggers three times: after two, twelve, and 48 hours. An irreversible red discoloration of the display signals the duration of the exceedance and helps assess product quality.

Cost-Effective Alternative to Conventional Monitoring Systems

In addition to single- and three-field indicators, Kager also offers two-field variants as well as a mini and long-term version. The long-term version can detect temperature exceedances for up to 168 hours and trigger up to five alert levels, making it particularly suitable for goods transported over multiple days.

Compared to expensive sensor systems or wireless measuring devices, WarmMark® indicators provide a cost-effective and straightforward solution. They not only enhance quality control in logistics but also offer valuable insights for optimizing packaging and transportation processes.

Visual Warning Against High Temperatures

Visual Warning Against High Temperatures: Kager’s Heat Indicators Protect Against Burns and Scalds

The German company Kager offers a wide range of self-adhesive temperature indicators for measuring and monitoring temperatures. Simple-to-use solutions like the Hot-Hand Indicator and Large Traffic Light Indicator provide clear visual warnings against touching hot surfaces. These products contribute to safety in workplaces where there is a risk of burns and scalds.

In many industrial workplaces, such as foundries, glass processing, chemical, and power plant industries, employees are exposed to increased risks of skin injuries from hot surfaces. Kager provides two self-adhesive warning labels that make this risk clearly visible.

The Hot-Hand Indicator is a round, black sticker (37 mm diameter) that turns red and displays the “HOT” label along with the symbol of a hand over flames when the temperature exceeds 50°C. The Large Traffic Light Indicator works on a traffic light principle: It changes from green to yellow to red for temperatures up to 70°C, signaling increasing danger.

Both indicators are reversible and universally understandable, making them an effective safety solution in various industries. Kager also offers many other temperature indicators for different applications.
