WiFi and GSM temperature & humidity monitoring for Ranchi's pharma, cold chain and industrial sites.
Ranchi · Jharkhand


About monitoring here
A logger in Ranchi is most often placed at hospital and blood bank and pharmaceutical sites around Dhurwa and the heavy engineering belt and Namkum and Tatisilwai industrial areas. Ranchi is the capital of Jharkhand, a city of lakes and hills on a cool, high stretch of the plateau, and a temperature data logger here serves a mix of heavy engineering, medicine, learning and trade. A large public-sector heavy engineering works stands at Dhurwa, and industrial areas at Namkum, Tatisilwai and Irba hold fabrication, packaging, food and warehouse firms. A big government medical institute and private hospitals draw patients from the whole state and beyond, while universities, an agricultural university and a technology institute at Mesra add laboratories. Main Road and Lalpur hold the wholesale and retail trade. Prithvi supplies WiFi loggers for wards, labs and shops on a network and GSM loggers for vans, trucks and stores out of range.
The plateau is milder than the plains in summer, the monsoon is heavy and winter nights are cold, so hospital refrigerators and pharmaceutical godowns meet damp for weeks and sharp chill within the same year. Dust from road works drifts in during the dry weeks, and condensation forms on cold surfaces after the first rains.
Areas
A big works and the firms that supply it hold spares, instruments and fabricated parts in large stores on wide campuses, with rooms far from any office.
Estates on the edge of the city hold fabrication, food, packaging and warehouse firms on plots of varied size, with trucks loading at the gates through the day.
A large government institute and private hospitals keep blood units, vaccines and medicines in refrigerators that serve patients from many districts.
Wholesalers of medicines, food and general goods work in crowded buildings, with chillers and stock rooms opened from early morning.
Industries
A medical institute and private hospitals receive patients from across the state, and an alert to the duty staff covers the minutes when the mains fails and the generator has not yet started.
Stockists supply chemists and hospitals across the plateau from back rooms and godowns, and a dated record answers a buyer who asks how a consignment of medicine was held.
Dairies, bakeries, caterers and packaged-food firms run chillers and cold rooms, and a reading from each unit shows the night a compressor began to fail.
University, institute and hospital laboratories keep samples and reagents in freezers and cabinets with their own limits, and an exported log supports a research file or an inspection.

Why Prithvi
FAQ
Yes. Every refrigerator and store appears on one dashboard with its own limit and its own alert recipients, and the person in charge of a department can export a report for any unit over any period.
Send the estate, the unit and a person to meet through the enquiry form, WhatsApp or a call, and we propose a day. Estates on different sides of the city are planned in one sequence. See how a Prithvi temperature data logger works.
Loggers run on batteries and keep recording through a cut, then send the stored readings when the network returns, so the record shows how long a room was warm.
VEGA Calibrations, our parent company, can calibrate loggers and probes, and the work can be booked together with the supply.
