Description
The Keller LEO1 is a digital pressure gauge with a fast peak-detection mode that samples at 1 kHz or more to catch pressure spikes and surges. It covers −1…3 bar up to 0…1,000 bar with ±0.1% FS accuracy and a ±0.2% FS total error band from 0 to 50 °C, and shows pressure together with min/max values.
Its 316L stainless steel sensor mounts with G¼ or ¼ NPT, the housing is IP65, and the battery lasts up to 1,000 hours in normal mode. The LEO1-Ei is an intrinsically safe version for hazardous areas.
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.
