Shipping and Transportation

Accurate temperature monitoring is crucial in shipping and transportation, where perishable goods rely on maintaining optimal temperatures to extend shelf life. Temperature deviations during transit can lead to product degradation, affecting everything from warehouses and cold rooms to grocery store refrigerators and freezers.

Compliance

Stringent regulations govern temperature control in the cold chain, necessitating an audit trail of temperature measurements at every stage. Tel-Tru integrates temperature sensing and data collection to preserve the quality of products throughout the supply chain. Temperature monitoring sensors can be deployed at every stage, whether in transit or in storage. From conventional industrial thermometers to smart wireless sensors, our instruments aid in recording accurate temperature readings, creating a comprehensive historical record of temperature conditions. This data is invaluable for analyzing trends, identifying areas for improvement, and ensuring regulatory compliance.

Products

Industrial Quality
Tel-Tru offers industrial quality temperature instruments in hundreds of options with threaded and sanitary fittings. The versatile case and stem configurations of the large industrial line can be adjusted to almost any angle for easy viewing, and are hermetically sealed per ASME B40.3.  The heavy duty-sanitary thermometer units meet 3A Standard Number 74-06, and feature Tri-Clamp sanitary fittings.

Wireless Sensors
Tel-Tru’s wireless temperature sensors leverage cellular connectivity to transmit real-time temperature information to a centralized monitoring system. The new Remo-Tel smart wireless temperature monitoring system allows processors to monitor temperature conditions 24/7 across disparate locations simultaneously, enabling swift intervention to preserve product integrity.

Calibration
Tel-Tru Check-Set thermometer calibrators used to validate cold storage inspection and process thermometers. Each calibrator is shipped with NIST traceable calibration certificate and accuracy recertification service available with reminder service when unit is registered. Tel-Tru digital thermometers can also be used as reference devices and calibration certification is available.

Spot Check Thermometers
Tel-Tru pocket sized spot checking thermometers are used by inspectors, service and maintenance personnel, and technicians for general checking in food service, refrigeration, and food processing applications. These gauges allow users to insert the probe directly into a product or environment to obtain a quick and accurate temperature reading. Whether it’s a grocery store display refrigerator or a refrigerated warehouse, Tel-Tru’s probe thermometers ensure precise temperature monitoring. They are also often modified for OEMs to use in limited space situations.
