Rangpo · Sikkim


About monitoring here
A logger in Rangpo is most often placed at pharmaceutical and food and beverage sites around Rangpo industrial estate and Majhitar and the university campus. Rangpo is the gateway town of Sikkim, on the Rangpo river at the boundary with West Bengal, and a temperature data logger here serves the first place that goods and visitors reach on the road into the state. Trucks stop at the checkpost, travellers have their permits checked, and traffic splits toward Gangtok and the other valleys. The Rangpo industrial estate, with the nearby area of Majhitar, holds the state's pharmaceutical plants and a distillery, a beverage unit and packaging firms, and a university campus stands at Majhitar. Hospitals and clinics serve the town and the surrounding villages in the valley. Prithvi supplies WiFi loggers for plants and clinics with a network and GSM loggers for trucks and stores out of range.
The river valley is warmer than the ridge above, the monsoon is very heavy and slides close the road, and cold nights come in winter, so a plant store can be warm and damp in the same week that a lorry waits in the mist.
Areas
An estate beside the river holds pharmaceutical plants, a distillery, beverage bottling and packaging firms, with raw-material rooms and finished-goods stores that need written records.
A neighbouring pocket holds further pharmaceutical units and a university campus whose laboratories keep samples and reagents in fridges and cabinets.
Trucks wait at the boundary for checks and for the road to open, so goods stand in vehicles in warm, damp air, sometimes for days.
Shops, wholesalers and clinics along the main road stock food and medicines for the town and nearby villages, with fridges and stock rooms in small buildings.
Industries
Formulation plants hold ingredients and finished packs in controlled rooms, and a continuous log of temperature and humidity supports each batch file and any customer audit.
Beverage bottlers, distillers and packaged-food firms hold stock that suffers in warm river air, and an alert on a phone reaches the owner when a store or chiller drifts.
Plant and university laboratories keep samples, cultures and reagents in freezers and fridges with their own limits, and an exported log supports a research file or an inspection.
Carriers load and wait at the gateway for the road into the mountains, and a GSM logger placed in a load records every hour the goods stood at the checkpost.

Why Prithvi
FAQ
Yes. A report for any room and period can be exported as PDF, Excel or CSV and sent to the customer, and access can be limited so each party sees only its own rooms.
A GSM logger placed in the load records temperature and humidity through the wait, so the owner and the buyer can see how long the goods stood and in what conditions. See how a Prithvi temperature data logger works.
Each site is a point on the same account with its own alert contacts, and a manager sees stores on both sides of the state line in a single list.
Our parent company, VEGA Calibrations, calibrates loggers and maps the temperature of stores, and for a Rangpo plant this can be arranged with the first supply and visit.
