About monitoring here
A logger in Mukalla is arranged case by case, whether for food and beverage or hospital and blood bank sites. Mukalla is a port city on the Gulf of Aden coast of eastern Yemen, the main coastal town of Hadramaut Governorate, with whitewashed buildings climbing from a curved bay beneath a rocky escarpment, and a temperature data logger here serves a fishing and trading town in a hot, humid setting. Boats land sardines, tuna and other fish at the harbour, where the catch is iced, salted, dried and processed, and traders sell dried fish, honey from the wadis and dates in the old markets. A university, hospitals and clinics serve the coast and the valleys behind it. Heat and humidity are high through much of the year, and sea air is salty. Prithvi loggers store their readings on their own batteries when a network is absent. Whether a given site can be supported is decided case by case after we hear from you.
The coast is hot and humid for most of the year, salt reaches every shed, and the dry months bring dust, so ice stores and drying yards face heat and damp together while rain is rare but can be heavy.
Areas
Boats land fish at the harbour and on the beaches, and ice stores, salting sheds and drying yards handle the catch in warm, wet and salty air.
Shops and stalls sell dried fish, honey, dates, spices and household goods in narrow streets of old buildings where stock rooms were never designed for cooling.
Hospitals, clinics and a university with laboratories keep vaccines, insulin and samples in refrigerators that must hold their ranges through any interruption of power.
Small warehouses near the shore hold food and household goods that arrive by sea or by road, in rooms that heat up under metal roofs.
Industries
Fish traders, honey and date dealers and grocers hold goods that lose quality in warmth and damp, and a record from each store shows when a cooler or an ice room began to drift.
Hospitals and clinics hold vaccines and blood products for the coast and the valleys, and an alert on a phone reaches the right person at once if a refrigerator warms.
Pharmacies and medicine distributors keep stock in rooms with stated ranges, and a dated log of temperature and humidity shows how a room behaved through the hottest weeks.
Goods that arrive by sea or by road wait in sheds and vehicles before they are used, and a logger placed among them records the heat and salty damp they met.

Why Prithvi
FAQ
That depends on the site. Supply to Yemen is looked at case by case, so send the place, the rooms and the situation, and we reply with what seems practical. See how a Prithvi temperature data logger works.
Warm, damp air enters when a door opens and condenses on cold surfaces, so a humidity trend beside the temperature shows how much moisture each landing brought in.
The logger goes on recording on its battery and stores the readings, so there is a record for the hours without power or signal, available when the site is next connected.
VEGA Calibrations, our parent company, looks after calibration of loggers and probes; share the model and the range you work to and we explain what could be considered for your site.
