Jamnagar · Gujarat


About monitoring here
Jamnagar lies near the Gulf of Kutch on the Kathiawar peninsula, and two things shape its storage: a very large refinery belt on the coast west of the city, and a brass-parts industry that has filled the Dared estate and the older lanes for decades. The refineries draw a supply chain of engineering shops, contractors, caterers, transport firms and chemical suppliers into the city, while naval and air force stations and a medical college add stores of their own. Bandhani tie-dye cloth and groundnut trade give the older side of the city its character. A temperature data logger in Jamnagar might be watching a lubricant store, a brass-parts warehouse or a hospital pharmacy, in salty air and a hot, dry climate that gives little rain.
The air is dry and hot for most of the year with a salty breeze off the gulf, rain is sparse and cyclones occasionally threaten the coast, so power cuts and corrosion are as real as heat.
Areas
The estate that made Jamnagar's name for brass parts, with foundries, machining shops and warehouses that hold finished components for export orders.
An older estate within reach of the city centre, where workshops, small engineering units and repair shops hold stock in cramped sheds.
The coastal belt west of the city with the refineries, contractors' yards and spares stores that serve continuous process plants and need steady storage conditions.
The small port on the gulf, with godowns for bulk cargo and general goods that wait for a vessel or a lorry in humid, salty air.
Dense lanes of bandhani cloth shops, groundnut traders, clinics and hotels around the old lake and palace, in buildings that hold the day's heat.
Industries
Suppliers to the refineries hold lubricants, additives and catalysts in stores with stated limits, and a reading in each room shows how it behaved on the hottest afternoon.
Brass-parts warehouses and port godowns hold goods for export orders, and a log at the dock door shows how long a lot stood in the salty heat before it was crated.
Groundnut and edible oil traders and hotel kitchens hold produce and oil that change when heat builds up, and a probe in each store gives a record a buyer can see.
A government hospital, a medical college and military and private hospitals keep blood banks and vaccine fridges that need alarms to reach staff when a storm interrupts the power.

Why Prithvi
FAQ
We supply loggers to any business with stores to watch. Tell us what you hold, the limits you work to and where the store is, and we propose points and alert contacts.
Salt in the air is hard on electronics, so we advise placing a logger indoors away from open doors and using a probe cable to reach a damp or exposed spot.
Yes. Each estate is its own site with alerts for its own team, and an owner with units in both sees them in one list, with reports that can be exported for any period.
Calibration of loggers and probes is delivered by VEGA Calibrations, our parent company, and can be timed with an audit date. Share the model and range and we explain the arrangement. See how a Prithvi temperature data logger works.
