Providing a reliable solution for cold chain environmental monitoring, the CE-compliant OM-80 series data loggers and readers employ a miniature weather-resistant design with a factory replaceable battery. Each logger can store up to 10,000 readings and is reusable. Built-in LEDs display high and low alarm verification indicating whether or not measured temperatures have remained within the user programmable alarm window throughout deployment. Stored data can be downloaded and saved to a computer using the reader and included software. Additionally, each package of data loggers comes with a certificate stating NIST-Traceability (No Points). Price starts at $90 for a five pack. OMEGA ENGINEERING INC., Stamford, CT. (800) 872-9436.
