About monitoring here
A logger in Nellore is most often placed at food and beverage and logistics and warehousing sites around Shrimp and fish processing plants and Hatcheries and farm stores. Nellore lies on the Penna river on the southern coast of Andhra Pradesh, and a temperature data logger here serves a district known for fish and shrimp farming. Ponds along the coast and the creeks supply hatcheries, ice plants and seafood processors that freeze, pack and export the catch, while rice mills hull the paddy of the Penna delta and granite, mica and quartz are quarried and dressed in the district. Krishnapatnam port, on the coast to the north-east, handles coal and containers, and a power station stands near it. Lorries leave for ports and airports at all hours. Hospitals serve the town and the villages around. Prithvi supplies WiFi loggers for plant rooms with a network and GSM loggers for reefers, farms and distant sheds.
The coast is hot and humid for most of the year, the north-east monsoon brings heavy rain and cyclone weather in the late months, and power cuts follow storms, so ice plants and cold rooms are tested exactly when roads are cut.
Areas
Processors clean, grade, freeze and pack the catch of the coastal ponds, with ice rooms, blast freezers and cold stores that must hold their limits through every shift.
Hatcheries and feed stores along the coast hold seed, feed and medicines that spoil in heat, in sheds far from towns and from any router.
Mills on the edge of the town hull and store rice in godowns that must stay dry, while stone works in the district keep chemicals and polishing materials in open sheds.
Warehouses and yards near the port hold cargo that waits for a ship or a truck, in salty, humid air and sun.
Industries
Seafood processors and exporters hold frozen and chilled product that must stay within limits from the plant to the container, and a record for each lot answers an overseas buyer who asks how it was kept.
Reefer lorries carry the catch to ports and airports, and a GSM logger placed with the load records every hour of the journey, so a delayed vehicle leaves a clear trace.
Stone-dressing and processing works keep resins, abrasives and bagged material with printed storage limits, and an alert from a hot shed lets the storekeeper act in time.
Hospitals in the town and the district hold vaccines and blood units that must survive cyclone-season outages, and an alert on a phone reaches the duty staff at once.

Why Prithvi
FAQ
Loggers in the ice room, freezer and cold store record the whole chain, and a report for the dates of one lot can be exported as PDF, Excel or CSV for the buyer abroad. See how a Prithvi temperature data logger works.
Loggers keep recording on their batteries and send an alert for a rising reading or a lost mains supply to the named person, so a failing compressor is found before a night's catch is lost.
Give us the place, the plant or farm and a person to meet through the enquiry form, WhatsApp or a call, and we plan a route that covers nearby sites on one trip.
Calibration of loggers and probes, and temperature mapping of a cold store, come from VEGA Calibrations, our parent company, and can be booked with the supply.
