Muzaffarpur · Bihar


About monitoring here
A logger in Muzaffarpur is most often placed at food and beverage and logistics and warehousing sites around Litchi orchards, packing sheds and cold rooms and Bela industrial area. Muzaffarpur is the litchi city of north Bihar, set on the Burhi Gandak river in a plain of orchards and flood-prone fields, and a temperature data logger here serves a trading centre for fruit, grain and food. Each May and June the famous litchi crop is picked, packed and sent by lorry and train to markets across India, and mangoes, bananas and vegetables follow through the year. The Bela industrial area holds food processors, bottlers and packaging firms, wholesalers fill the old lanes, and a large medical college hospital serves the districts of the north. The railway junction links the city to Patna, Delhi and the east. Prithvi supplies WiFi loggers for rooms with a network and GSM loggers for orchards, lorries and distant stores.
Summers are hot and heavy with humidity, the monsoon swells the rivers and cuts roads, and winters bring cold mornings and fog, so fruit cold rooms must work hardest in the weeks when the roads are least reliable.
Areas
Growers and traders pack the fruit in sheds and chill it in cold rooms for a few weeks each year, when a failed compressor can spoil a day's picking.
An estate on the edge of the city holds food processors, beverage bottlers, packaging firms and godowns, with lorries loading beside the gates at all hours.
Wholesalers of grain, pulses, food and general goods work in crowded lanes around the old markets, with stock rooms packed to the roof in hot, humid buildings.
A large teaching hospital and private clinics keep blood units, vaccines and medicines in refrigerators that serve patients from many districts.
Industries
Litchi and mango traders, pulp makers and bottlers hold fruit and drinks that spoil within days in the heat, and a record for each chamber and lorry shows how a lot was kept.
Reefer trucks and trains carry fruit to far cities, and a GSM logger placed in the load records every hour of the journey, so a delay on a flooded road leaves a clear trace.
A teaching hospital and clinics serve patients from the north, and an alert on a phone means a failing blood or vaccine refrigerator is found in the night.
Vaccines reach district centres across the north by road, and a logger in the carrier shows whether the doses stayed within range during a hot or flooded journey.

Why Prithvi
FAQ
A logger in the packing shed, the cold room and the lorry records each stage, and a report for the dates of one lot can be exported for the buyer.
Loggers record on their batteries through a cut and send an alert for a lost supply, so the owner knows a chamber is no longer protected even when roads are cut.
Give us the place, the unit and a person to meet using the enquiry form, WhatsApp or a call, and we propose a day. Sites in different directions are planned in a sensible order. See how a Prithvi temperature data logger works.
Calibration of loggers and probes comes from VEGA Calibrations, our parent company, and the visit can be set together with the supply.
