Description
The WIKA CPB3800 is a compact hydraulic dead-weight tester for calibrating pressure instruments on site or in the laboratory. Standard tungsten carbide piston-cylinder systems cover 1–120, 2.5–300, 5–700 or 10–1,200 bar with 0.05% of reading accuracy (0.025% option), and the integrated dual-area spindle pump fills the system and sets the pressure finely.
Optional CPS5800 single- and dual-range piston systems raise accuracy to 0.015% (premium 0.006%) and switch ranges automatically. The base weighs 13.5 kg and runs on VG22 mineral oil.
Argonmark Ltd supplies WIKA 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.
