About monitoring here
A logger in Doha mostly serves hospital and blood bank sites, as well as pharmaceutical sites. Doha is the capital city of Qatar, built around a curved bay on the east coast of the peninsula, and a temperature data logger here serves a city of hospitals, hotels, food importers and warehouses in the very hot, humid coastal climate of the Gulf. A palm-lined Corniche follows the water, traditional dhows ride at anchor beside towers of glass, and the low lanes of an old market sell spices, textiles and food. Newer districts of offices, apartments and clinics spread inland, with industrial and warehouse areas on the outskirts. Long summers push every cooling system to its limit, and sea air, dust and sudden haze add to the strain. Enquiries from Doha are handled through the enquiry form, Call or WhatsApp.
Summer afternoons are far beyond comfortable and the nights stay warm, humid sea air carries salt onto every shed, and dust storms blow in from the desert in some seasons, so cold rooms, kitchens and vehicles all work against the weather for months. A refrigerator that loses power on an August afternoon warms fast, vehicles standing in the sun reach far higher temperatures than the shaded air, and condensation forms the moment a cold door opens.
Areas
Hospitals, specialist clinics and diagnostic laboratories hold vaccines, insulin, blood products and samples in refrigerators and freezers that must hold a range through any interruption of power.
Hotels, restaurants and catering firms run walk-in coolers, freezers and dry stores in basements and back corridors, where heat from the kitchen adds to the load on the cooling.
Importers and supermarkets hold chilled and frozen food in cold rooms and reefer boxes before it moves to shops and kitchens across the city.
Warehouses and workshops on the edge of the city hold stock for shops and businesses under metal roofs that heat up quickly in the summer sun.
Industries
Doha hospitals and blood services hold vaccines and blood products to strict ranges, and a phone alert reaches the person on duty if a refrigerator drifts in the middle of the night.
Medicine distributors and pharmacies in Doha store stock to labelled ranges, and a dated log of temperature and humidity shows how a room behaved through the hottest weeks of summer.
Hotel kitchens, caterers and food importers around Doha hold chilled and frozen stock, and a record from each cooler shows when a compressor began to struggle.
Goods that arrive for Doha wait in warehouses and vehicles before use, and a logger placed in a consignment records the heat and humidity each lot met.

Why Prithvi
FAQ
A logger in each cooler, freezer and dry store records through the day and night, and a report for any period can be exported in PDF, Excel or CSV form for an inspector or a client. See how a Prithvi temperature data logger works.
The coast is damp as well as hot, and cold rooms form condensation whenever a door opens to the outside, so a humidity trend beside the temperature shows moisture that a thermometer alone would miss.
The logger keeps recording on its own battery and stores the readings, so the hours of an outage are still on record when the site is connected again.
Calibration of loggers and probes for Doha laboratories is looked after by VEGA Calibrations, our parent company; share the model and the range you work to and we outline the options.
