Check-Set Calibrator for fast, easy, and accurate verification.
Remo-Tel®
The Remo-Tel Industrial Temperature Monitoring System automates temperature data logging and provides a 24/7 online monitoring dashboard for industrial and commercial operations to help mitigate risk for product loss and system failure and improve productivity. The Remo-Tel System is ideal for a wide variety of processes including Refrigeration, Molding, Brewing and other extremely time sensitive temperature monitoring applications.
Thermowells
Thermowells for sanitary applications as well as thermowells that can be treated and documented to NACE standards. Thermowells are recommended for pressure, corrosive fluid, or high velocity applications. Produced using highest quality material and machined from solid bar stock for standard or high velocity requirements in a large selection of materials and coatings. Designed and manufactured to assure perfect alignment with the thermometer stem.
Glass Industrial
Our glass industrial thermometers are versatile and adjust-angle, with a lens front and red liquid fill. They are NIST calibrated and guaranteed accurate to ± one scale division.

Specimens, particularly biological samples, are sensitive to environmental conditions such as temperature. Deviations from optimal storage temperatures can lead to degradation of biomolecules, denaturation of proteins, or chemical reactions that alter sample composition. Inadequate temperature control can foster microbial growth, risking contamination of samples. Real-time temperature monitoring helps prevent such deleterious effects, preserving specimen integrity and purity.
Many laboratory specimens, including biological tissues, cell cultures, and chemical compounds, require long-term storage for future research or clinical applications. Temperature plays a pivotal role in maintaining the stability of these specimens over extended periods. Proper temperature monitoring ensures that storage conditions remain consistent, minimizing degradation and maximizing the shelf life of stored specimens.
Regulatory agencies impose stringent guidelines for the storage of laboratory specimens, particularly those used in research, diagnostics, or clinical trials. Accurate temperature monitoring is essential for maintaining sample traceability and demonstrating compliance with regulatory requirements. Temperature records serve as crucial documentation during audits, inspections, or quality assessments, verifying that specimens have been stored under appropriate conditions.
Laboratories invest significant resources in collecting, processing, and storing specimens, making them invaluable assets for scientific inquiry. Any compromise in storage conditions, such as temperature excursions or equipment malfunctions, can result in catastrophic losses or irreparable damage to specimens. Regular temperature monitoring allows for early detection of anomalies, enabling timely intervention to mitigate risks and safeguard specimen collections.
Certain laboratory specimens, such as biological samples or pharmaceutical compounds, may require strict adherence to cold chain management principles to maintain their integrity during transportation and storage. Temperature monitoring throughout the cold chain ensures that specimens are maintained within specified temperature ranges, minimizing the risk of degradation or spoilage. By optimizing cold chain management, laboratories can uphold the quality and efficacy of stored specimens, particularly those intended for clinical use or research.
