About monitoring here
A logger in Silchar is most often placed at pharmaceutical and hospital and blood bank sites around Trading lanes at Rangirkhari and Tarapur and Transport yards and the hill-road terminals. Silchar is the main city of the Barak Valley in southern Assam, on the Barak river, and a temperature data logger here serves a trading city that looks toward Manipur, Mizoram and Tripura as much as toward Guwahati. Trucks bring goods over the hill roads for the valley and carry them onward, a railway line and an airport at Kumbhirgram link the city, and wholesalers stock food, medicines and consumer goods for shops across the south. A central university and a medical college hospital serve students and patients, tea gardens stretch across the valley, and bamboo has long fed a paper industry. Prithvi supplies WiFi loggers for wards, shops and offices on a network and GSM loggers for trucks, hill-road yards and stores out of range.
Rain is very heavy in the monsoon, the valley is humid year round and floods have repeatedly covered low streets, so refrigerators work through long outages and cartons take on damp in every godown. Landslides on the hill roads can hold a lorry for days.
Areas
Wholesalers stock food, medicines and general goods for the valley and the hill states, in crowded buildings where back rooms are hot and damp.
Trucks load at yards on the road toward Manipur and Mizoram, and goods wait in vehicles and sheds between long, slow legs through the hills.
A central university with laboratories and a medical college hospital hold samples, blood units and vaccines in fridges and freezers.
Gardens around the valley store made tea in humid factories, and paper and bamboo suppliers hold stock in sheds that take up damp air.
Industries
Medicine distributors serve chemists in the valley and in the hill states beyond, and a logger placed with a pack records the whole range of conditions it met on the hill road.
The medical college hospital and clinics serve patients from three states, and an alert to the duty staff covers the minutes when mains and generator fail together.
Wholesalers of food, dairy and packed goods store stock that suffers in heavy air, and a reading from each chiller shows when a unit failed during a flood outage.
Carriers bridge the valley and the hill states by road, and landslides can hold a lorry for days, so a logger in the load records how long the goods waited and in what conditions.

Why Prithvi
FAQ
Yes. A GSM logger placed with the goods records readings along the journey and through any halt, and the owner can open the record on a phone and export it for the buyer. See how a Prithvi temperature data logger works.
The logger keeps recording on its own memory and battery and sends the stored readings when the signal returns, so the record has no gap.
We mount the logger body above the likely water line and run only the probe cable to the cold space, and battery operation keeps the record going if the supply is cut.
For a Silchar hospital or laboratory, our parent company VEGA Calibrations calibrates the loggers and probes, and the visit can be booked with the supply order.
