About monitoring here
Nagpur lies almost in the middle of the country, where the main north–south and east–west routes cross, and that position shapes its storage. Goods bound for the east, south and north pass through its rail yards and warehouses, oranges from the Vidarbha orchards are graded and chilled here, and the city's hospitals draw patients from a wide region. Industry sits in estates on the edges: Hingna to the west, Butibori on the highway to the south, and the MIHAN project near the airport, which joins a cargo hub to a special economic zone. A temperature data logger in Nagpur has to cope with some of the hottest summers in India, when a closed shed or a parked van can be far hotter than the air outside. Alerts to a phone give a small team a way to watch many rooms.
Summers are extremely hot and dry, with heat building from April to June, then a moderate monsoon raises humidity and the winter is mild and dry, so cooling plant works hardest exactly when the outside air is at its worst.
Areas
A MIDC estate on the western side and one of the city's biggest, with engineering, electronics, food and pharmaceutical units on plots of every size.
A very large estate on the highway towards Hyderabad, with textile, chemical, engineering and warehousing plants on big plots that stand far apart.
The multi-modal cargo hub and airport project beside the airport, with a cargo terminal, a special economic zone and newer warehouses and technology units.
An estate on the western highway in orange country, where food processors and engineering firms work close to the groves and the farms that supply them.
The old city grain and vegetable market at Itwari and the larger produce market at Kalamna, where goods are traded in bulk before being sent on to towns across the region.
Industries
Orange traders, grain dealers and dairies chill and hold produce through the long summer, and a log for each chamber shows how many hours the temperature climbed whenever grid power dipped.
Large government and private hospitals draw patients from the surrounding states and run blood banks, vaccine fridges and pharmacies that must hold their range through every power cut.
Warehouses at MIHAN and along the national highways serve as a staging point for goods in every direction, so loads often wait here between long journeys in sun-heated sheds.
Medicine distributors serve hospitals and chemists across the region from stores that must stay in range through the hottest weeks, and a dated log answers a buyer's questions.

Why Prithvi
FAQ
The loggers in our range carry their own batteries and keep recording through a cut, so the log shows the whole period the power was off and how far the room warmed. See how a Prithvi temperature data logger works.
Yes. Each site is its own entry on the dashboard with alerts for the people who run it, and a head of quality sees all of them in one list and can compare their records side by side.
Fruit chambers and packing sheds are watched for humidity as well as temperature, since dry air shrinks fruit and damp air invites mould. A logger that reads both suits the job.
Yes, through VEGA Calibrations, our parent company, which also carries out temperature mapping of larger stores. Tell us the model and the range and we explain how it is planned with a site visit.
