Description
The Keller ECO 2 is a compact and economical digital pressure gauge with a piezoresistive sensor, available for −1…30 bar or 0…300 bar. It reads twice per second with accuracy better than 0.5% FS and shows the current pressure together with the maximum or minimum since the last reset; a zero function allows relative readings or barometric compensation.
Its 316L stainless steel sensor is fitted with a 360° swivel and G¼ connection, the housing is IP65, and it runs about 1,000 hours on a coin cell. The ECO 2 Ei version is intrinsically safe (Ex ia IIC T5) for Zone 0.
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.
