Product Description

The Monument 258F Gas Test Gauge with its extended 600mm length offers enhanced measurement range and sensitivity for more demanding gas testing applications. This longer format provides greater precision when working with lower pressure differentials or when more detailed readings are required on commercial installations. Manufactured in Britain from tough plastic, this gauge incorporates a plastic U-tube with a comprehensive millibar scale that adjusts for zeroing water level, ensuring accurate baseline readings. The ingenious extruded cover slides off and clips over the base to create a stable vertical stand during operation, whilst the hanging tab allows for vertical suspension from suitable protrusions when wall or pipework mounting is preferable. Features and Benefits: • 600mm extended length provides enhanced measurement sensitivity and range • Ideal for commercial applications requiring precise pressure readings • Durable plastic construction ensures longevity in professional environments • Convertible standing and hanging configurations for operational flexibility • Suitable for comprehensive testing of both domestic and commercial gas systems Specifications: Tool Type: Gas Test Gauge Size (mm): 600 Size (in): 24 Capacity: 60 Millibar
