What lid lets me log temperature, pH, CO₂ and pressure from the top of a tri-clamp fermenter? · Hardware · basis: Xem Studio design on the standard solid cap of each size: a 1½ in clamp port at the centre and a ring of PG13.5 probe ports, Ø6 O-ring probe glands, ¼ NPT half couplings and a ½ in hose barb

Exact dimensions. True size, with no printing tolerance added.

Notes

For a vessel that can only be fitted through the top. Centre 1½ in clamp: a bubbler gravity cap, a thermowell, a dip tube, a carb stone or a racking cap. PG13.5 ports: pH, dissolved O₂ or CO₂ probes. Ø6 glands: temperature probes at two depths. ¼ NPT: a pressure transducer or gauge and a gas-in valve (nitrogen or CO₂). Barb: blow-off hose, or a gas-flow meter on the CO₂ coming off.
Weight is read with the vessel on a scale; gravity can be read with the bubbler cap instead of a floating hydrometer.
Every clamp face is the ISO 2852 profile used across this site: 2.85 mm rim, flat face with the gasket groove (K 1.6 deep, R3 1.2 bottom, 23° walls, P2 0.8 edges) on C2, 20° back cone. Flange C3 / groove C2 / tube OD × wall, mm: ½–¾ in 25.0 / 20.4 (derived) / 12.7–19.05 × 1.65; 1–1½ in 50.5 / 43.5 / 25.4–38.1 × 1.65; 2 in 64.0 / 56.5 / 50.8 × 1.65; 2½ in 77.5 / 70.5 / 63.5 × 1.65; 3 in 91.0 / 83.5 / 76.2 × 1.65; 4 in 119.0 / 110.0 / 101.6 × 2.11; 6 in 166.9 (6.570 in) / 156.5 / 152.4 × 2.77; 8 in 217.7 (8.570 in) / 207.0 / 203.2 × 2.77; 10 in 268.5 / 261.0 / 254.0 × 3.40; 12 in 319.3 / 311.8 / 304.8 × 3.40.
