​“bun THERMOMAX” is a temperature recorder and alarm system with an external sensor for extremely low or high temperatures. It is powered by 2 replaceable AA batteries for up to 6 years and connects directly to Wi-Fi. More than an accurate meter and a reliable logger, “bun THERMOMAX” is also a cloud-based alarm system. All setting parameters like measurement intervals, upload intervals, minimum and maximum allowed temperature thresholds can be set through a web-based application on any platform. It sends out email and text message alarms as soon as temperature exceeds or falls below pre-set limits. It also provides access to the records history, graphs and periodical reports. Its hardware and software installation is very easy and does not require any specific tools or applications. *Temperature measurement will be less accurate in sensors with wider temperature range. To achieve highest accuracy narrower temperature range is recommended. “Bun THERMOMAX” can drive 2,3,4 wire RTD sensors. PT type, range and accuracy (Class Y [1/3 B], Class A, Class B) can vary based on order and calibration. By default, “Bun THERMOMAX” has a Y Class PT1000 sensor in a stainless-steel pocket with a 1.5 meter length cable. The cable includes 2 silver coating wires with PTFE cover and Fiberglass sleeving. *Depends on reading and upload intervals and environmental conditions. Battery life is more than 6 years in a standard set up. (Standard set up is room temperature 20°C measurement every 15 minutes upload every 48 hours).
