State
A logger in Kerala mostly protects seafood stores, port warehouses and hospital stores. Kerala is a long, narrow state between the sea and the hills, and its storage is arranged along the coast road and the railway. Kochi in the middle is the great port, Thiruvananthapuram in the south is the capital with its technology park, hospitals and research institutes, and Kollam holds cashew and fisheries. Thrissur trades in gold and herbal medicine, while Kozhikode in the north still moves spices, timber and oil. The air is warm and very humid for most months and the monsoon is heavy and long, so condensation, mould and storm power cuts matter as much as heat. Each page below describes one city, its rooms and the loggers that suit them.

FAQ
Kochi has a city page covering Kakkanad, Kalamassery and Edayar, and Thiruvananthapuram, Kozhikode, Thrissur and Kollam have city pages of their own. Other places in the state are served on enquiry. See how a Prithvi temperature data logger works.
Warm, wet air condenses on cold-room doors and probes, so we place probes away from seals and coils and set alerts for a door left open, which is the usual cause of fog and ice.
Yes. A report for the cold room and for the container can be exported for each lot, so an overseas buyer sees the conditions from the store to the port.
