About monitoring here
A logger in Puducherry is most often placed at pharmaceutical and electronics sites around Mettupalayam industrial estate and Thirubuvanai and Sedarapet estates. Puducherry is a seaside town on the Coromandel coast laid out by the French on a neat grid of streets, and a temperature data logger here serves a city that blends tourism and learning with a surprising amount of industry. The White Town with its yellow colonial buildings, the beach promenade, cafes and guesthouses draw visitors all year, and a large medical institute and several medical colleges treat patients from far beyond the territory, and a central university stands at Kalapet. Industrial estates at Mettupalayam, Thirubuvanai, Sedarapet and Thattanchavady hold pharmaceutical, food, engineering and electronics plants. Lorries leave the estates for Chennai and the ports through the day. Prithvi supplies WiFi loggers for wards and plants with a network and GSM loggers for trucks, yards and stores out of range.
The coast is hot, salty and humid for most of the year, the north-east monsoon brings heavy rain and cyclone weather in the last months, and storms cut the power for days, so metal rusts and cartons take on moisture in sheds near the sea.
Areas
A large estate on the western side of the town holds pharmaceutical, food, plastics and engineering plants on regular plots, with raw-material rooms and finished-goods stores behind secured gates.
Estates further out hold electronics, pharmaceutical and engineering units on wide plots, whose stores stand far apart and whose lorries wait at the gates in the afternoon sun.
A smaller estate close to the town holds light industry, packaging and godowns in crowded sheds that trap heat and damp.
Hotels, cafes and guesthouses in old French houses run coolers in cramped spaces, while a large medical institute and private hospitals hold blood units, vaccines and medicines.
Industries
Formulation plants in the estates hold ingredients and finished packs in controlled rooms, and a continuous log of temperature and humidity supports each batch file and any customer audit.
Makers of electronic and electrical goods store boards and sealed assemblies where salty damp air causes faults, and a humidity trend shows a quality team when a store drifted.
Hotels, cafes, bakeries, breweries and packaged-food firms run coolers and cold rooms through hot, humid weeks, and an alert reaches the supervisor when a unit warms on a busy weekend.
A large medical institute and other hospitals receive patients from the territory and from neighbouring districts, and a dated record backs each handover for blood units and vaccines.

Why Prithvi
FAQ
Yes. The engineer or manager on duty receives a phone and email alert as soon as a cooler passes its limit, and a second person can take over if there is no reply.
We mount the logger body indoors, clear of spray and wet walls, let only the probe lead enter the cold space, and suggest wiping the probe whenever the room is cleaned.
Write with the estate, the plant and someone to ask for, by the enquiry form, WhatsApp or a call, and we fix a day. The estates lie in different directions from the town, so they are visited in order. See how a Prithvi temperature data logger works.
VEGA Calibrations, our parent company, can calibrate loggers and carry out temperature mapping, and the visit can be planned with the supply.
