Taiz · Taiz Governorate


About monitoring here
A logger in Taiz is arranged case by case, whether for hospital and blood bank or pharmaceutical sites. Taiz is a hill city in the south-west highlands of Yemen, built on the lower slopes of Mount Sabir and overlooking a fertile plain, and a temperature data logger here serves a busy commercial town of hospitals, universities and workshops in a mild, damp climate. Narrow streets climb the hillsides, an old citadel looks down from a rock above the centre, and large markets sell food, cloth and household goods to the whole governorate. Many small factories and trading houses work from compact premises, and clinics and hospitals draw patients from the villages around. Mornings are often misty, afternoons warm and the rainy season is wet. The loggers keep their readings in memory on battery power if a network drops. We look at every request from Taiz case by case.
Altitude keeps the air cooler than on the coast, but mist, summer rain and steep hillsides bring damp into stores, so rooms swing between warm afternoons, cool nights and wet spells. Heavy traffic and steep lanes mean that loads reach shops late and unevenly, so goods may stand in a hot vehicle or a cold doorway longer than planned. Many buildings on the hillsides have grown by extension over decades, which gives uneven rooms where one wall faces the sun and another the rock.
Areas
Wholesalers and shopkeepers stack food, oil, cloth and household goods in basements and back rooms cut into the slope, where damp rises from the rock.
Large hospitals, private clinics and university laboratories keep vaccines, blood products and samples in refrigerators that must ride through every interruption of power.
Small plants that bake, pack, bottle and process food run chilled rooms and finished-goods stores in compact buildings on the edges of town.
Distributors and pharmacies across the city hold stock in rooms that warm under flat roofs in the afternoon and chill on clear nights.
Industries
Taiz 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 overnight.
Medicine importers and pharmacies in Taiz store stock to labelled ranges, and a dated log of temperature and humidity shows how a room behaved through a wet week.
Bakers, dairies and packers around Taiz supply a crowded city, and a log from each cold room shows a retailer how a batch was kept before it left the plant.
University and clinical laboratories in Taiz keep reagents and samples to set limits, and an exported report is ready when a review asks for one.

Why Prithvi
FAQ
A logger in the refrigerator records every hour and sends a phone alert if the range is crossed. Whether a given Taiz site can be supported is decided case by case, so send the details and we reply. See how a Prithvi temperature data logger works.
Rain runs down slopes and into lower rooms, and rock walls hold moisture, so a humidity trend shows damp that temperature alone would not reveal.
The logger goes on recording from its battery and keeps the readings, so the hours without mains power are still logged and can be read when the site next connects.
For laboratories in Taiz, calibration of loggers and probes is handled through VEGA Calibrations, our parent company. Tell us the model and the range you work to and we outline the choices.
