RP Water manothermograph

The Gastech RP 1 PLUS Water Manothermograph is an electronic pressure and temperature recording instrument housed in a rugged, watertight yellow carry case rated for field deployment on active construction sites. The unit contains a graphic LCD display, a four-button operating panel for test type selection, and an integrated common-paper graphic printer that produces on-site pressure test certificates. The system accepts an additional external sensor input as standard — with optional external sensors available in 70 mbar, 25 bar, 40 bar, and 160 bar ranges. The supply package includes a 5-meter spiral hose with quick-release fittings, a ½” NPT adapter with quick-release, a temperature probe with ½” NPT pocket, a 220/12V self-limiting battery charger, and a one-year calibration certificate. The instrument is calibrated and certified annually per applicable regulatory requirements.

Test type selection covers six certified test protocols: low-pressure service connection testing per UNI-CIG 9860, gas network testing up to 5 bar per UNI 9865, and pipeline testing for 6th, 5th, 4th, and 3rd species durations of 4 or 24 hours under D.M. 24.11.84. The temperature monitoring function gives the RP 1 PLUS a complete measurement profile covering both pressure and thermal behavior across the test duration. The integrated common-paper printer outputs a certified hardcopy test record immediately on-site, eliminating post-test data transfer requirements. The microprocessor architecture controls all test functions and automatically manages data recording across the selected test duration.

The Gastech RP 1 PLUS Water Manothermograph is deployed by gas network operators, hydraulic installers, and utility contractors during statutory pressure testing and commissioning of buried and above-ground gas and water pipelines — including underground service connections, aerial pipeline sections, and gas distribution network segments up to 3rd species classification. It replaces up to eight conventional manothermograph units in a single instrument, covering all pressure test categories from a single device.

Leader Infra supplies this multi-protocol, integrated-printer pressure recording instrument for gas and water network operators — delivering on-site certified pressure test documentation across all statutory test categories from D.M. 24.11.84, UNI 9860, and UNI 9865 in a single rugged field unit.

FAQ — Does the RP 1 PLUS require a separate printer or PC to generate the certified test certificate? No. The unit contains a fully integrated common-paper graphic printer that outputs the pressure test certificate directly on-site at the conclusion of each test. The printed certificate includes the full test record — pressure curve, temperature data, test duration, and test type — ready to attach to the distribution company documentation file without any external equipment or data transfer step.
