Profec 63 mm Glycerin-Filled Pressure Gauge with Bottom Connection, -1 to 5 bar / -15 to 75 psi
This glycerin-filled pressure gauge from Profec delivers stable, vibration-dampened readings across a dual-scale dial graduated in both bar and psi. The 63 mm stainless steel case and polycarbonate window make it equally suited to pool plant rooms, irrigation control panels, pump stations, and greenhouse dosing systems. Glycerin filling protects the movement against pressure spikes, condensation, and continuous pulsation — common challenges in recirculating water circuits.
The bottom-entry male thread (1/4″ BSP) allows direct mounting into tee pieces, manifold ports, or valve bodies without additional adapters in most standard installations. The scale runs from -1 bar (full vacuum) to 5 bar, covering the complete operating range of domestic pool pumps, booster sets, and drip-irrigation controllers. Accuracy class 1.6 % of full scale meets EN 837-1 requirements for industrial and process instrumentation.
Especificaciones

Compatibilidad
Suitable for water, hydraulic oil, and non-aggressive media compatible with brass and phosphorous bronze wetted parts. The 1/4″ BSP male thread connects directly to standard 1/4″ female BSP ports on pool filter housings, pump discharge manifolds, irrigation solenoid valve blocks, and pressure-reducing valve test points. Not recommended for media that attack brass or polycarbonate. Verify chemical compatibility before use with chlorinated concentrates or aggressive fertiliser solutions.

En detalle
- Glycerin fill dampens pump pulsation and vibration for steady, easy-to-read pointer position
- Dual bar/psi scale suits mixed-standard installations without conversion
- Vacuum-to-positive range (-1 to 5 bar) detects suction-side blockages as well as discharge pressure
- Stainless steel case resists corrosion in humid pool and greenhouse environments
- Bottom-entry 1/4" BSP thread fits most manifold and valve ports without adapters
- Polycarbonate window may yellow or craze with prolonged UV exposure if installed outdoors without shielding
- Fixed-range gauge — cannot be re-ranged; a separate gauge is required for systems operating above 5 bar
- Glycerin fill can leak if case seal is damaged; gauge must be replaced, not repaired on site
