RP 1 Plus & RP 1 Plus48

The Gastech RP 1 Plus & RP 1 Plus 48 are electronic pressure and temperature recording instruments for statutory gas and water pipeline testing, each housed in an identical rugged watertight yellow field case. Both units contain a graphic LCD display, a four-button operating panel, and an integrated common-paper graphic printer that outputs certified test records on-site. The RP 1 PLUS covers test durations of 30 minutes, 4 hours, and 24 hours across all applicable gas pipeline categories. The RP 1 PLUS 48 extends this to a maximum 48-hour test duration and additionally supports water installation testing up to 160 bar via optional external sensors. Both units accept optional external sensors at 70 mbar, 25 bar, 40 bar, and 160 bar ranges. The standard supply for both includes a 5-meter spiral hose with quick-release fittings, a ½” NPT adapter, a temperature probe with ½” NPT pocket, a 220/12V self-limiting battery charger, and a one-year calibration certificate.

Both instruments are microprocessor-controlled, covering test protocols under D.M. 24.11.84, UNI 9860, and UNI 9165 — from low-pressure user connections through to gas pipelines of 3rd species classification with external sensors. Each unit replaces up to eight conventional manothermograph units, consolidating the full range of low and medium pressure test categories into a single device. The customizable company header on the printed test certificate allows each distribution operator to output documentation directly branded to their organization. Both units are built for active construction site conditions — the sealed case withstands field handling, moisture, and the temperature conditions typical of outdoor network maintenance operations.

The Gastech RP 1 Plus & RP 1 Plus 48 are deployed by gas network operators, hydraulic contractors, and utility field technicians during statutory pressure testing and commissioning of buried and above-ground gas pipelines, service connections, and aerial pipeline sections across the Italian methane and LPG gas distribution network — and, in the case of the Plus 48, water distribution network testing up to 160 bar. The 48-hour test duration covers high-species pipeline certification requirements under D.M. 24.11.84 that the standard 24-hour RP 1 PLUS cannot address alone.

Leader Infra supplies both variants of this multi-protocol field pressure recorder for gas and water network operators — covering the complete range of mandatory test durations and pipeline species classifications from a single instrument family, with on-site certificate printing and external sensor flexibility built in.

FAQ — What is the key operational difference between the RP 1 PLUS and the RP 1 PLUS 48? The RP 1 PLUS supports maximum test durations of 24 hours, covering gas pipeline species 4th, 5th, and 6th under D.M. 24.11.84. The RP 1 PLUS 48 extends the maximum duration to 48 hours — required for certain higher-species pipeline certifications — and additionally covers water installation pressure testing up to 160 bar via optional external sensors, making it the more complete instrument for operators working across both gas and water network infrastructure.
