Description
The Keller DCX-22 is a family of autonomous water level and temperature loggers in a 22 mm 316L stainless steel housing, for shallow or deep wells. The plain DCX-22 is fully submersible, the SG/VG versions bring a cable up to a read-out housing, and the DCX-22 AA adds a built-in barometric sensor so readings are air-pressure compensated without vent tubes.
Ranges run to 100 mWC with a typical error band of 0.05 %FS, readings are time-stamped in 57,000-value memory, and the AA lithium battery lasts about ten years at one reading per hour. An optional ARC-1 module can send data by SMS.
Argonmark Ltd supplies Keller instruments across Bangladesh — Dhaka, Chattogram, Gazipur, Narayanganj and the gas fields, refineries, terminals and power plants beyond. Send us the model, range, process connection, output and any hazardous-area requirement, and we will confirm the right configuration, lead time and price.
