About monitoring here
A logger in Sana'a is arranged case by case, whether for hospital and blood bank or pharmaceutical sites. Sana'a is a highland city of western Yemen, set on a broad plateau more than two thousand metres above sea level and surrounded by mountains, and a temperature data logger here serves a city of hospitals, markets and workshops in a mild, dry climate. Its Old City, a World Heritage site, is a dense quarter of tall brick houses with decorated windows, covered markets and walled gardens, while the newer districts spread north and south along the valley. Shops sell coffee, raisins, honey, grain and spices, and pharmacies, clinics and a large university serve a wide area. Afternoons are warm and nights are cold, and rain falls mainly in summer. The loggers keep their readings in memory on battery power when a network is absent. Every request from Sana'a is looked at case by case.
At this altitude the air is thin and dry, the sun is strong, and the gap between a warm afternoon and a cold night can be wide, with winter nights close to freezing and a short summer rainy season, so stores swing between dry warmth and brief damp.
Areas
Covered markets sell coffee, raisins, spices, honey and household goods from small shops and back rooms in old brick buildings, where thick walls hold cool air in the morning and heat in the afternoon.
Large hospitals, private clinics and a university with teaching laboratories keep vaccines, blood products, insulin and samples in refrigerators that must hold a range through every interruption of power.
Wholesalers and pharmacies spread through the newer districts hold medicines in storerooms where the cold of a winter night and the sun of an afternoon both pass through the walls.
Bakeries, dairies, juice makers and grocery warehouses supply the households of a large city from compact premises, with refrigerators and cold rooms working all day.
Industries
Hospitals and blood services hold vaccines and blood products for a very large catchment, and a phone alert reaches the person on duty if a refrigerator drifts in the small hours.
Medicine importers, wholesalers and pharmacies store stock to stated ranges, and a dated record of temperature and humidity shows how a room behaved through a cold night or a warm, bright afternoon.
Dairies, bakers, coffee and raisin dealers and grocers hold goods that lose quality when warm or damp, and a log from each store shows a buyer how a lot was kept.
University and clinical laboratories keep reagents and samples to set limits, and an exported report is ready whenever a review asks for one.

Why Prithvi
FAQ
A logger in the refrigerator records every hour and sends a phone alert when the range is crossed. Whether a given site can be supported is decided case by case, so send the details and we reply.
Summer storms and the condensation of cold nights add moisture to rooms that are otherwise dry, and coffee, paper and some medicines react to it, so a humidity trend shows what temperature alone misses.
It keeps recording on its battery and stores the readings, so there is a record for the hours without power or signal, to be read when the site is next connected. See how a Prithvi temperature data logger works.
Calibration of loggers and probes for Sana'a sites is looked after by VEGA Calibrations, our parent company. Share the model and the range you work to and we outline the choices for your site.
