Temperature Indicators

Temperature indicators allow you to visually detect if a product has been exposed to temperatures outside its permitted range. They are essential for cold chain control and for transporting pharmaceutical, food, biotech, chemical or electronic products, where excessive heat or cold can compromise product integrity.

At Conservatis, we offer irreversible, reversible and multi-level indicators that provide reliable information on thermal exposure, helping ensure traceability, regulatory compliance and product quality.

Temperature indicator solutions

Low-temperature indicators (cold)

Designed to detect exposure to temperatures below the defined limit. Ideal for products that must not freeze or that require controlled refrigeration.

• ColdMark

High-temperature indicators (heat)

Show whether the product has exceeded a critical temperature that may affect its stability, quality or safety. Widely used in pharmaceuticals, cosmetics and food industries.

• WarmMark

Multi-level indicators

Solutions that detect several critical temperatures in a single label, providing a more complete reading of the product’s thermal history.

• WarmMark Multi-Level
• ColdMark Multi-Level (subject to availability)

Time–temperature indicators

Devices that combine time and temperature control, showing whether a product has remained too long above or below the permitted range.

• Timestrip (thermal versions)
• Timestrip PLUS

Smart indicators with connectivity

Visual indicators combined with simple electronic functionalities, designed for fast verification in sensitive products.

• SpotBot BLE (indicator mode)
  
  
  

Benefits of temperature indicators

Using temperature indicators helps ensure that sensitive products remain within their correct thermal range from origin to destination. Their immediate visual reading allows incidents during transport or storage to be detected, reducing risks, costs and claims.

They are also essential tools in audits, certifications and quality controls. Being passive devices, they require no energy, calibration or maintenance, making them an economical and reliable option for any company handling temperature-sensitive products.
