New temperature sensors from Lamerholm
May 21st 2008

Lamerholm has launched the ShockWatch range of temperature-sensitive environmental indicators. The new temperature sensors, ColdMark and WarmMark, are designed to provide a reliable indication of temperature fluctuations for goods in transit and storage.

The small, easy to use sensors can be applied to any clean, dry surface. They provide indisputable visual evidence of exposure to unacceptable temperature levels. The tamper-proof indicators are available for a wide variety of temperature thresholds.

ColdMark activates when exposed to temperatures below a predetermined level and comes in four temperature activation levels: -3ºC, 0ºC, +5ºC and +10ºC. Activation occurs when the product has been exposed to unacceptable temperatures for 30 minutes or more.

WarmMark uses a proprietary technique to indicate when the item has been exposed to temperatures above a predetermined threshold. Response temperature ranges for WarmMark are -18ºC to +37ºC, +10ºC to +34ºC and +10ºC to +25ºC. Other WarmMark products include the Duo that monitors duration of exposure of a product above two activation temperature levels, and the Long Run that allows for a longer exposure to temperatures above the threshold level.

The new indicators provide evidence that items have been exposed to temperatures outside acceptable limits, alleviating safety concerns surrounding bacterial growth, infection and contamination while a shipment is in transit. The products are ideal for monitoring both fresh and frozen food, pharmaceutical and medical products as well as other temperature-sensitive items such as electronic components and chemicals.
